Io - Galileo

Io hemisphere facing away from Jupiter

Io
This Galileo image of Jupiter's moon Io was produced from a number of high resolution images taken on 6 November 1996 and enhanced color images from 7 September 1996. This shows the hemisphere which faces away from Jupiter. The variation in color is due to sulfur-rich compounds. The black, gray, and red regions due to recent volcanism - Io is the most volcanically active body in the solar system. The topographic and color variations are dramatic. The high resolution images were taken at distances ranging from 245,000 to 403,000 km. The smallest discernable features are about 2.5 km in size. Io is 3640 km in diameter and north is up.
