Galileo's Legacy at Jupiter

artist's concept of Galileo at Jupiter
The Asteroid 243 Ida and its Moon Dactyl

This color picture is made from images taken from the Galileo spacecraft about 14 minutes before its closest approach to asteroid 243 Ida on August 28, 1993. The range from the spacecraft was about 10,500 kilometers (6,500 miles). The images used are from the sequence in which Ida's moon was originally discovered; the tiny moon is visible to the right of the asteroid. The color is "enhanced" in the sense that the CCD camera is sensitive to near infrared wavelengths of light beyond human vision; a "natural" color picture of this asteroid would appear mostly gray.
