Ida - Galileo
False color image of asteroid 243 Ida and Dactyl
Galileo false-color image of asteroid 243 Ida and its
small satellite Dactyl (at right). The images used to
make this picture were taken about 14 minutes before
closest approach form a distance of roughly 10,500 km.
Color differences may indicate compositional variation
on the surface. The bright blue areas may indicate
greater abundance of iron bearing minerals. Ida is
58 km along its long axis, and north is at 1:00.
