Ganymede is the third of Jupiter’s four large moon, with volcanic Io and ice-rich Europa located interior to it, and the heavily cratered Callisto orbiting beyond it.

A geologic map of Jupiter's largest moon Ganymede is superimposed over a global color mosaic of the Galilean moon made of images from NASA's Voyager 1, 2 and Galileo spacecraft.

Ganymede is a particularly weird place. Not only is it Jupiter’s most massive satellite, it’s the biggest moon in the whole solar system.

NASA’s Juno spacecraft this week beamed back amazing images of Ganymede, a moon of Jupiter and the largest in our solar system.

The American space agency's Juno probe has returned some close-in views of Ganymede - one of Jupiter's four Galilean moons and the largest natural satellite in the Solar System.

Ganymede's surface can be divided into older, heavily cratered, dark terrain (∼ 34% by area, based on a global 2-km-resolution mosaic produced by P.M.S.) and younger, resurfaced, bright terrain ...
