With additional observations coming in, scientists at NASA's Near-Earth Object Office at the Jet Propulsion Laboratory in Pasadena, Calif. have been able to further refine the trajectory estimate for the orbit of asteroid 2010 GA6. This latest trajectory indicates that the closest approach for asteroid 2010 GA6 will be just slightly beyond the moon's orbit, about 434,000 kilometers (270,000 miles) from Earth. The time of closest approach will be 7:06 p.m. Pacific Daylight Time on April 8 (2:06 U.T.C. on April 9).
A newly discovered asteroid, 2010 GA6, will safely fly by Earth this Thursday at 4:06 p.m. Pacific (23:06 U.T.C.). At time of closest approach 2010 GA6 will be about 359,000 kilometers (223,000 miles) away from Earth - about 9/10ths the distance to the moon. The asteroid, approximately 22 meters (71 feet) wide, was discovered by the Catalina Sky Survey, Tucson, Az.
"Fly bys of near-Earth objects within the moon's orbit occur every few weeks," said Don Yeomans of NASA's Near-Earth Object Office at the Jet Propulsion Laboratory in Pasadena, Calif.
NASA detects and tracks asteroids and comets passing close to Earth using both ground and space-based telescopes. The Near-Earth Object Observations Program, commonly called "Spaceguard," discovers these objects, characterizes a subset of them and plots their orbits to determine if any could be potentially hazardous to our planet.
