Ganymede Jupiter III Taking a new step...is what people fear most. - Dostoyevski. Ganymede [GAN-ee-meed] is the largest moon of Jupiter and is the largest in our solar system with a diameter of 5,262 km (3,280 miles). If Ganymede orbited the Sun instead of Jupiter it could be classified as a planet. Like Callisto, Ganymede is most likely composed of a rocky core with a water/ice mantle and a crust of rock and ice. Its low density of 1.94 gm/cm 3, indicates that the core takes up about 50% of the satellite's diameter.
Orbit: 1,070,400 km from Jupiter. Ganymede is the largest moon in the Solar System and the seventh moon and third satellite outwards from Jupiter. There are known to be 67 moons orbiting around Jupiter. The four largest moons are Ganymede, Io, Europa and Callisto, all of which were discovered by Galileo.
