How Many Decimals of Pi Do We Really Need?

By NASA/JPL Edu

Pi to the 15th decimal is shown in a speckled starry band as a silhouetted face looks out over colorful concentric circles and black and white images of an atom, molecules, Earth, and the Voyager spacecraft. The left side of the image fades to black with

While world record holders may have memorized more than 70,000 digits of pi, a JPL engineer explains why you really only need a tiny fraction of that for most calculations – even at NASA.

Update: October 24, 2022 – This article, originally written in 2016, has been updated to reflect the latest values for NASA’s Voyager 1 spacecraft, which continues to venture farther into interstellar space. The author, Marc Rayman, has ventured on too, from the chief engineer for NASA’s Dawn mission, which concluded successfully in 2018, to the chief engineer for mission operations and science at NASA’s Jet Propulsion Laboratory.

The decimals of pi are listed out on an orange background with a large pi symbol in the background.

We received this question from a fan on Facebook who wondered how many decimals of the never-ending mathematical constant pi (π) NASA-JPL scientists and engineers use when making calculations:

“Does JPL only use 3.14 for its pi calculations? Or do you use more decimals, like say [360 or even more]?”

Here’s JPL’s Chief Engineer for Mission Operations and Science, Marc Rayman, with the answer:

Thank you for your question! This isn't the first time I've heard a question like this. In fact, it was posed many years ago by a sixth-grade science and space enthusiast who was later fortunate enough to earn a doctorate in physics and become involved in space exploration. His name was Marc Rayman.

To start, let me answer your question directly. For JPL's highest accuracy calculations, which are for interplanetary navigation, we use 3.141592653589793. Let's look at this a little more closely to understand why we don't use more decimal places. I think we can even see that there are no physically realistic calculations scientists ever perform for which it is necessary to include nearly as many decimal points as you asked about. Consider these examples:

  1. The most distant spacecraft from Earth is Voyager 1. As of this writing, it’s about 14.7 billion miles (23.6 billion kilometers) away. Let’s be generous and call that 15 billion miles (24 billion kilometers). Now say we have a circle with a radius of exactly that size, 30 billion miles (48 billion kilometers) in diameter, and we want to calculate the circumference, which is pi times the radius times 2. Using pi rounded to the 15th decimal, as I gave above, that comes out to a little more than 94 billion miles (more than 150 billion kilometers). We don't need to be concerned here with exactly what the value is (you can multiply it out if you like) but rather what the error in the value is by not using more digits of pi. In other words, by cutting pi off at the 15th decimal point, we would calculate a circumference for that circle that is very slightly off. It turns out that our calculated circumference of the 30-billion-mile (48-billion-kilometer) diameter circle would be wrong by less than half an inch (about one centimeter). Think about that. We have a circle more than 94 billion miles (more than 150 billion kilometers) around, and our calculation of that distance would be off by no more than the width of your little finger.
    2. The illustration shows a cartoonish Voyager 1 flying in space with a conical signal eminating from its antenna. An inset shows a more distant view of Voyager with a line extending to Earth and a distance label between the Voyager and Earth marked ~131 AU.

    Put your pi math skills to the test with this problem from NASA's Pi Day Challenge. Can you use pi to determine what fraction of a signal from Voyager 1 reaches Earth? Image credit: NASA/JPL-Caltech | + Expand image | › View lesson page

  2. We can bring this closer to home by looking at our planet, Earth. It is more than 7,900 miles (12,700 kilometers) in diameter at the equator. The circumference is roughly 24,900 miles (40,100 kilometers). That's how far you would travel if you circumnavigated the globe – and didn't worry about hills, valleys, and obstacles like buildings, ocean waves, etc. How far off would your odometer be if you used the limited version of pi above? The discrepancy would be the size of a molecule. There are many different kinds of molecules, of course, so they span a wide range of sizes, but I hope this gives you an idea. Another way to view this is that your error by not using more digits of pi would be more than 30,000 times thinner than a hair!
    3. A view of Earth from space showing East Africa, the Middle East, and Asia with swirls and splotches of clouds across the planet.

  3. Let's go to the largest size there is: the known universe. The radius of the universe is about 46 billion light years. Now let me ask (and answer!) a different question: How many digits of pi would we need to calculate the circumference of a circle with a radius of 46 billion light years to an accuracy equal to the diameter of a hydrogen atom, the simplest atom? It turns out that 37 decimal places (38 digits, including the number 3 to the left of the decimal point) would be quite sufficient. Think about how fantastically vast the universe is. It’s certainly far beyond what you can see with your eyes even on the darkest, most beautiful night of sparkling stars. It’s yet farther beyond the extraordinary vision of the James Webb Space Telescope. And the vastness of the universe is truly far, far, far beyond what we can even conceive. Now think about how incredibly tiny a single atom is. Isn’t it amazing that we wouldn’t need to use many digits of pi at all to cover that entire unbelievable range?

The oldest-known galaxy identified in the image is 13.1 billion years old. Image credit: NASA, ESA, CSA, STScI | + Expand image | › More about the image | Text description (PDF)

Pi is an intriguing number with interesting mathematical properties. It’s fun to think about its truly endless sequence of digits, and it may be surprising how often it appears in the equations scientists and engineers use. But there are no questions – prosaic or esoteric – in humankind’s noble efforts to explore or comprehend the marvels of the cosmos, from the unimaginably smallest scales to the inconceivably largest, that could require very many of those digits.

Hear more from Marc in his inspiring TEDx talk, “If It Isn’t Impossible, It Isn’t Worth Trying” and in his Dawn Journal, where he wrote frequent updates about the Dawn mission’s extraordinary extraterrestrial expedition to the protoplanet Vesta and dwarf planet Ceres.

August

The Voyagers Turn 45

The twin Voyager spacecraft launched in 1977 on a journey to explore the outer planets and beyond – and they're still going. Now more than 12 billion miles (19 billion kilometers) from Earth in a region known as interstellar space, they're the most distant human-made objects in space.

Get a primer on these fascinating spacecraft from Teachable Moments, then use it as a jumping off point for lessons on the scale, size, and structure of our solar system and how we communicate with distant spacecraft.

Lessons & Resources:

September

Rendezvous with an Asteroid

A distant asteroid system 6.8 million miles (11 million kilometers) from Earth was the site of NASA's first attempt at redirecting an asteroid. On September 26, the Double Asteroid Redirection Test, or DART, mission impacted the asteroid Dimorphos in an attempt to alter its speed and path around a larger asteroid known as Didymos. Dimorphos and Didymos do not pose a threat to Earth, which makes them a good proving ground for testing whether a similar technique could be used to defend Earth against potential impacts by hazardous asteroids in the future.

Get a primer on the DART mission and find related resources for the classroom in this article from our Teachable Moments series. Plus, explore our collection of standards-aligned lessons and activities all about asteroids to get students learning about different kinds of space rocks, geology, and meteoroid math.

Lessons & Resources:

A Closer Look at Europa

Just a few days later, on September 29, the Juno spacecraft that had been orbiting Jupiter since 2016 captured the closest views of Jupiter’s moon Europa in more than 20 years. The ice-covered moon is thought to contain a subsurface liquid-water ocean, making it an exciting new frontier in our search for life beyond Earth. NASA's Europa Clipper mission, which is scheduled to launch in 2024 is designed to study the moon in more detail. But until Europa Clipper arrives at the Jovian system in 2030, these observations from Juno are our best chance to get a closer look at this fascinating moon.

Learn more about Europa and why it is interesting to scientists in this talk from our Teaching Space With NASA series featuring a Europa Clipper mission scientist. Then, explore our Ocean Worlds Lesson Collection for ideas on making classroom connections.

Lessons & Resources:

October

Celebrate Halloween Like a Space Explorer

The month of October is the perfect time to get students exploring our STEM activities with a Halloween twist. Students can learn how to carve a pumpkin like a JPL engineer, take a tour of mysterious locations throughout the solar system, and dig into the geology inside their Halloween candy.

October 31 is also JPL's 86th birthday, which makes October a great time to learn more about JPL history, including the team of female mathematicians known as "human computers" who performed some of the earliest spacecraft-tracking calculations and the Laboratory's role in launching the first U.S. space satellite.

Lessons & Resources:

November

Watch a Total Lunar Eclipse

Look up in the early morning hours of November 8 to watch one of the most stunning spectacles visible from Earth: a total lunar eclipse. This one will be viewable in North and South America, as well as Asia and Australia.

Learn more about lunar eclipses and how to watch them from our Teachable Moments series. Then, get students of all ages outside and observing the Moon with lessons on moon phases and the hows and whys of eclipses. Students can even build a Moon calendar so they always know when and where to look for the next eclipse.

Lessons & Resources:

Artemis Takes a Giant Leap

NASA is making plans to send astronauts back to the Moon for the first time since 1972 – this time to establish a sustainable presence and prepare for future human missions to Mars. The first major step is Artemis I, which is testing three key components required to send astronauts beyond the Moon: the Orion spacecraft, the Space Launch System, or SLS, rocket and the ground systems at Kennedy Space Center in Florida. The uncrewed Artemis I mission marks the first test of all three components at once.

Get your K-12 students following along with lessons in rocketry and what it takes to live in space. Plus, register to follow along with the mission with resources and updates from NASA's Office of STEM Engagement.

December

Satellite Launches on a Mission to Follow the Water

As crucial as water is to human life, did you know that no one has ever completed a global survey of Earth’s surface water? That is about to change with the launch of the SWOT mission. SWOT, which stands for Surface Water Ocean Topography, will use a state-of-the-art radar to measure the elevation of water in major lakes, rivers, wetlands, and reservoirs. It will also provide an unprecedented level of detail on the ocean surface. This data will help scientists track how these bodies of water are changing over time and improve weather and climate models.

Engage your students in learning about Earth’s water budget and how we monitor Earth from space with these lessons. And be sure to check out our Teachable Moments article for more about the SWOT mission and the science of our changing climate.

Prepare for the Science Fair

Before you know it, it'll be science fair time. Avoid the stress of science fair prep by getting students organized and thinking about their projects before the winter recess. Start by watching our video series How to Do a Science Fair Project. A scientist and an engineer from JPL walk your students through all the steps they will need to create an original science fair project by observing the world around them and asking questions.

The Best New STEM Education Resources from NASA-JPL in 2021

By Kim Orr

Collage of top 10 educational resources from NASA/JPL for 2021

In 2021, we added nearly 80 STEM education resources to our online catalog of lessons, activities, articles, and videos for educators, students, and families. The resources feature NASA's latest missions exploring Earth, the Moon, Mars, asteroids, the Solar System and the universe beyond. Here are the 10 resources our audiences visited most this year.

NASA's Mission to Mars Student Challenge

To kick off the year, we invited students, educators, and families from around the world to create their own mission to Mars as we counted down to the Perseverance rover's epic landing on the Red Planet in February. More than one million students participated in the Mission to Mars Student Challenge, which features seven weeks of guided education plans, student projects, and expert talks and interviews highlighting each phase of a real Mars mission.

It's no surprise that this was our most popular product of the year. And good news: It's still available and timely! With Perseverance actively exploring Mars and making new discoveries all the time, the challenge offers ongoing opportunities to get students engaged in real-world STEM.

Need a primer on the Perseverance Mars rover mission, first? This article from our Teachable Moments series has you covered.

Solar System Size and Distance

This video offers a short and simple answer to two of students' most enduring questions: How do the sizes of planets compare and how far is it between them? Plus, it gets at why we don't often (or ever) see images that show all the planets' sizes and distances to scale. Spoiler alert: It's pretty much impossible to do.

Get students exploring solar system size and distance in more detail and even making their own scale models with this student project.

Code a Mars Helicopter Video Game

As you'll soon see from the rest of this list, coding projects were a big draw this year. This one took off along with Ingenuity, the first helicopter designed to fly on Mars, which made its historic first flight in April. Designed as a test of technology that could be used on future missions, Ingenuity was only slated for a few flights, but it has far exceeded even that lofty goal.

In this project, students use the free visual programming language Scratch to create a game inspired by the helicopter-that-could.

Just updated for 2022, this project is part educational activity and part art for your walls. Students learn about moon phases to complete this interactive calendar, which shows when and where to see moon phases throughout the year, plus lists moon events such as lunar eclipses and supermoons. The art-deco inspired design might just have you wanting to make one for yourself, too.

The NASA Pi Day Challenge

This year marked the eighth installment of our annual Pi Day Challenge, a set of illustrated math problems featuring pi (of course) and NASA missions and science. Don't let the name fool you – these problems are fun to solve year round.

Students can choose from 32 different problems that will develop their math skills while they take on some of the same challenges faced by NASA scientists and engineers. New this year are puzzlers featuring the OSIRIS-REx asteroid mission, Mars helicopter, Deep Space Network, and aurora science.

Educator guides for each problem and problem set are also available here. And don't miss the downloadable posters and virtual meeting backgrounds.

Another coding challenge using the visual programming language Scratch, this project is inspired by the Perseverance Mars rover mission, which is collecting samples that could be brought back to Earth by a potential future mission.

While developing a gamified version of the process, students are introduced to some of the considerations scientists and engineers have to make when collecting samples on Mars.

Code a Mars Landing

As if launching a rover to Mars wasn't hard enough, you still have to land when you get there. And that means using a complex series of devices – from parachutes to jet packs to bungee cords – and maneuvers that have to be performed remotely using instructions programmed into the spacecraft's computer.

Students who are ready to take their programming skills to the next level can get an idea of what it takes in this project, which has them use Python and microcontrollers to simulate the process of landing a rover on Mars.

How Far Away is Space?

Without giving the answer away: It's not as far as you might think.

In this activity, students stack coins (or other objects) on a map of their local area as a scale model of the distance to space. The stacking continues to the International Space Station, the Moon, and finally to the future orbit of the James Webb Space Telescope, which is slated to launch on Dec. 22.

A person puts a shape onto the tangram rover outline.

Build a Rover and More With Shapes

You don't have to be a big kid to start learning about space exploration. This activity, which is designed for kids in kindergarten through second grade, has learners use geometric shapes called tangrams to fill in a Mars rover design. It provides an introduction to geometry and thinking spatially.

Once kids become experts at building rovers, have them try building rockets.

A person holds seven cards over the Space Voyagers game mat.

Space Voyagers: The Game

Technically a classroom activity (it is standards-aligned, after all), this game will appeal to students and strategy card game enthusiasts alike. Download and print out a set for your classroom (or your next game night).

Players work collaboratively to explore destinations including the Moon, Mars, Jupiter and Jupiter's Moon Europa with actual NASA spacecraft and science instruments while working to overcome realistic challenges at their destination including dust storms and instrument failures.

JPL Internship Program Expanding Diversity in STEM

By Taylor Hill

Five years in, a JPL initiative forging relationships with students and faculty at historically Black colleges and universities continues expanding its reach, hosting 48 interns this year.

Brandon Ethridge, a flight systems engineer at NASA’s Jet Propulsion Laboratory in Southern California, has had a year to remember. The 24-year-old got engaged, became a father, and is celebrating the one-year anniversary of starting full time at JPL – his self-described dream job.

“Definitely the most eventful year of my life,” Ethridge said.

While he’s been gaining experience testing systems used to build spacecraft, Ethridge has spent minimal time at the Laboratory due to the pandemic. But the North Carolina native already had plenty of first-hand knowledge of JPL thanks to his summer 2019 internship – an opportunity that presented itself at a JPL informational session that spring at his alma mater, North Carolina A&T State University.

“That allowed me the chance to speak one-on-one with Jenny Tieu and Roslyn Soto [JPL Education project managers],” Ethridge said. “They were incredibly generous with their time and provided resume critiques, feedback, and general advice about how to get an opportunity at JPL.”

Since 2017, Tieu has been leading JPL’s Historically Black Colleges and Universities/Underrepresented Minorities, or HBCU/URM, initiative – an effort to increase and foster a more diverse workforce in technical roles at the Laboratory. It’s one of many programs facilitating the more than 550 internship opportunities offered through the Education Office this year.

Now in its fifth year, the program has seen rapid growth; from seven interns in its first year, to 24 interns in 2020. This year, JPL is welcoming 48 students interning remotely from institutions including Howard, North Carolina A&T, Tuskegee, and Prairie View A&M universities, along with underrepresented-minority students from universities including UCLA, USC, UC Riverside, Duke, Cal Poly Pomona, and more.

Interns at JPL

How to Get an Internship at JPL

Learn about the world of JPL internships, the skills that will help you stand out, and how to get on the right trajectory even before college.

The initiative includes funding and support to bring in faculty from the schools to take part in research with the students, building in a cohort model that facilitates sustainable interactions with JPL.

“We’re intentional about addressing the culture shock that some of these students may experience,” Tieu said. “With the cohort model, the faculty members can provide guidance to the students while they are navigating new relationships, connections, and a new city.”

Additionally, interns are invited to participate in roundtable conversations in groups where they can share concerns and openly discuss their experiences at JPL. Tieu has also set up virtual meet-ups where students can get to know employees from outside their groups and hear talks from members of JPL’s Black Excellence Strategic Team and past HBCU alumni.

For Ethridge, being in a position to give back to the program was something he prioritized.

“I wanted to repay some of the many kindnesses that were afforded to me,” Ethridge said. “I also feel that I am in a unique position because I just recently went through the process.”

For Howard University junior Kyndall Jones, the draw to JPL came following a fellow student’s acceptance into the program.

“I was so amazed that he had an internship with NASA, and it really sparked my interest,” Jones said. “After doing my research on the program, I submitted my resume and heard back after a few months, landed an interview, and now here I am [virtually]!”

Despite the telework nature of this summer’s internship, Jones said that even from her home in Dayton, Ohio, she has been able to foster connections with JPL employees and gain valuable experience in her role working on software for an Earth-science instrument that will help NASA understand how different types of air pollution, which can cause serious health problems, affect human health.

And thanks to her mentor, Operations Systems Engineer Janelle Wellons, Jones was able to get the type of hands-on NASA experience that’s been hard to come by since the pandemic.

“My mentor Janelle suggested that I come visit Los Angeles for a few days this summer, and I was finally able to visit and explore the city for the first time,” Jones said. “I am also super grateful for her setting up a tour at the NASA Armstrong Flight Research Center where we were able to view, tour, and learn lots of interesting facts about NASA’s historical aircraft.”

Wellons – who splits her time operating instruments aboard several Earth-observing missions – had been involved in previous years’ roundtable discussions with HBCU interns, but this year, she had the opportunity to hire her own interns through the program. Being from the East Coast herself, Wellons remembers having little awareness of JPL as a potential career landing spot while studying at Massachusetts Institute of Technology.

“Getting visibility and actually partnering with these schools to make these internships happen is so important,” Wellons said. “Actively interacting with HBCUs is only going to do good for people we would otherwise potentially never get an application from, and it benefits JPL by broadening the talent pool and diversity of our workforce.”

As for the future, Jones sees the initiative as one step of many for her and fellow interns toward careers in engineering and science.

“I know a lot of Howard students that are interning or have interned with JPL, and the love from our College of Engineering and Architecture is especially high,” Jones said. “The info sessions, resume workshops, and networking workshops that JPL has been able to put on have been great, and the more they can do, the better for students.”

Tieu agrees, adding, "We are happy to see the growth of the initiative but look forward to making further progress. There's so much more we would like to accomplish in the years ahead."

The Summer School for Space Mission Mavericks

By Celeste Hoang

When Jennifer Scully was a planetary geology grad student at UCLA in 2013, she happened upon an email that called for students to apply to something called the Planetary Science Summer School, or PSSS.

“I asked around and everybody only had positive things to say,” she says, “so I applied and I got in.”

She found herself in an immersive, 11-week program that teaches students all over the country how to formulate, design, and pitch a mission concept to a review board of NASA experts – essentially, how to bring a space mission to life from beginning to end.

“It was fabulous,” Scully says of her time in the program. “I come from a science background, and I had worked on an active planetary mission, but I didn’t have much experience with engineering. The summer school gave me my first exposure to mission-concept development and proposals. It was really illuminating.”

Seven years later, Scully is now a geologist at NASA's Jet Propulsion Laboratory in Southern California, researching the asteroid Vesta and dwarf planet Ceres. She also plays a role in planning and designing missions to explore Jupiter's moon Europa. She’s still part of the PSSS program – but, now, as one of the mentors to this year’s cohort of 36 students looking at missions to Venus and Saturn's moon Enceladus.

The first 10 weeks of the program focus on formulation and always happen remotely via webinar. The final week usually culminates with an intensive in-person experience at JPL, during which participants write their mission proposal. Participants receive mentorship from scientists and engineers with the laboratory's Team X, a group that has been helping design and evaluate mission concepts since 1985. Even though the pandemic means their “culminating week” won’t take place physically at the laboratory this year, the students are still descending virtually on the JPL community between July 20 and Aug. 7 to learn the complex dance of what does and doesn’t work when it comes to dreaming up a NASA mission.

“We do this for the broader planetary science mission community,” says PSSS manager Leslie Lowes, who’s been leading the program since 2010. “It’s about NASA training the next generation of scientists and engineers to do this type of work. Over 650 alumni use this model of mission design, and they’re in all kinds of leadership positions across NASA, including at JPL.”

Developed in 1989, the summer school started as a lecture series on how space missions could address the latest science discoveries and gradually shifted to a more hands-on format in 1999. Instead of hearing about the process, why not let students experience it?

“The first thing we do [when participants arrive at JPL] is help them evaluate potential architectures for their mission. Is it an orbiter or a lander? Is it a flyby?” says Alfred Nash, a mentor for the summer school and a lead engineer for Team X. “Does the science work? Do the engineering and cost work? The problem is not ‘can you make the thing,’ but ‘can you make the thing within the boundaries you have?’”

For Team X, it’s all about an integrated approach, which is one of the principal differences between how missions were developed in earlier days of exploration versus more recently. “Team X itself, its superpower is its ability to work in parallel and concurrently,” Nash says, stressing the importance of how the science should work in parallel with the engineering, the storytelling, the cost, and the project management.

“What is the big thing I’m trying to do? How do all the pieces work together? What is the foundational heart of this in terms of how we’re going to change humanity’s understanding? What are the pieces we need so that happens, and what does it take to do that?” are common questions Nash says Team X asks of all its mission proposals – including the concepts developed in PSSS.

One key lesson Nash tries to impart during the culminating week: “Win [the proposal] and don't regret it when you do,” he says. “The last thing you want to do is design a mission that no one can manage.”

If the students’ answers can pass the rigorous initial hurdles and meet the requirements for a NASA proposal, then they transition to design work. At that point, each student is paired with a mentor who has expertise in a range of engineering capabilities, from mission design to the science tools that will go on a spacecraft.

While this would normally mean working together at JPL, the program has gone virtual this year.

Team X had some practice setting up a virtual experience for the summer’s incoming students, as most JPL employees have been on mandatory telework since mid-March. Currently, the students are in a “waterfall of [web meeting] rooms,” as Nash describes it, where there’s one central meeting room and then individual “stations” in separate rooms, where students and mentors can interface while moving from room to room as needed. A typical day kicks off at 8 a.m. with a daily briefing. Then, students spend half the day with Team X and half the day on their own, preparing for the next day’s tasks. Their day ends at 5 p.m. with a briefing to review what was completed, what worked well, what didn’t, and what needs to change for the next day.

“Everyone knows science, if they’re a scientist, and engineering, if they’re an engineer,” says PSSS alumna Scully. “But now, they’re really trying to understand what mission development is about. This foundation will enable them to work with NASA much more effectively.”

The cohorts that arrive every year are formidable, and this summer’s group is no different: Among the students are 26 Ph.D. candidates and eight postdoctoral researchers.

For Elizabeth Spiers – a Ph.D. candidate studying the habitability of other planets at the Georgia Institute of Technology, and one of this summer’s students examining Enceladus’ ocean – PSSS has provided her with invaluable experience in real-time mission concept problem-solving.

“The project moves quickly and some of our decisions must be made equally as fast,” Spiers says. “Oftentimes, no person on our team knows the answers, and we need to figure out what we don’t know or understand about the problem so that we can ask the correct questions swiftly.”

In addition to critical thinking, the summer school also gives its students the chance to work with a diverse group of students and mentors.

“It’s really exhilarating to see all of those disparate backgrounds and expertise come together into one cohesive project,” Spiers says. “I have learned so much about not only our project and the science and engineering related to it, but also about my teammates and their individual passions.”

Over the years, the program has taught students lessons they can carry with them throughout their careers. PSSS alumna Jessica Watkins went on to become a NASA astronaut and, at JPL, two summer school alumni-led development of science instruments on the Perseverance Mars rover – PIXL and SHERLOC. And this year, there’s a new star in the program, literally: The summer school is piloting a second experience called the Heliophysics Mission Design School to help strengthen hypothesis-driven science investigations when designing missions to the Sun.

Perhaps one lesson students will take away from PSSS is not only knowing what they want, but also recognizing the limits of space exploration.

“The most rewarding thing is seeing them make good decisions,” says Nash. “When they avoid trying to do something too expensive just because it’s cool. When they find a more fruitful way forward. What you want has nothing to do with it; it’s about what the world will let you do and how clever you are at navigating those boundaries.”

Doing the Math on Why We Have Leap Day

By Lyle Tavernier

Animated illustration of Earth orbiting the Sun

You may have noticed that there's an extra day on your calendar this year. That's not a typo; it's leap day! Leap day is another name for Feb. 29, a date that typically comes around every four years, during a leap year. Why doesn't Feb. 29 appear on the calendar every year? Read on to find out how the imperfect match between the length of a calendar year and Earth's orbit results in the need to make small adjustments to our calendar on a regular basis. Explore leap day resources for students, too.

The length of a year is based on how long it takes a planet to revolve around the Sun. Earth takes about 365.2422 days to make one revolution around the Sun. That's about six hours longer than the 365 days that we typically include in a calendar year. As a result, every four years we have about 24 extra hours that we add to the calendar at the end of February in the form of leap day. Without leap day, the dates of annual events, such as equinoxes and solstices, would slowly shift to later in the year, changing the dates of each season. After only a century without leap day, summer wouldn’t start until mid-July!

But the peculiar adjustments don't end there. If Earth revolved around the Sun in exactly 365 days and six hours, this system of adding a leap day every four years would need no exceptions. However, Earth takes a little less time than that to orbit the Sun. Rounding up and inserting a 24-hour leap day every four years adds about 45 extra minutes to every four-year leap cycle. That adds up to about three days every 400 years. To correct for that, years that are divisible by 100 don't have leap days unless they’re also divisible by 400. If you do the math, you'll see that the year 2000 was a leap year, but 2100, 2200 and 2300 will not be.

After learning more about leap years with this article from NASA's Space Place, students can do the math for themselves with this leap day problem set. Follow that up with writing a letter or poem to be opened on the next leap day. And since we've got an extra 24 hours this year, don't forget to take a little time to relax!
