Ganymede - Galileo

Global view of Ganymede's trailing hemisphere

This Galileo image of the trailing hemisphere of Jupiter's moon Ganymede uses enhanced colors to bring out details. At 5262 km in diameter, Ganymede is the largest moon in the solar system. The north and south polar areas can be distinguished by their light purple shade in this image, possibly due to small particles of frost. The light, younger grooved terrain and the older dark furrowed terrain can be easily seen, as can many bright impact craters. The resolution of this image, taken from a distance of 918,000 km, is about 18 km and north is up. (Galileo, MRPS-94229)
