Ganymede
The largest moon in the solar system/Moons
Ganymede is the largest moon in the solar system, even bigger than the planet Mercury. It is the only moon known to possess its own internally generated magnetic field. Ganymede is one of Jupiter's four Galilean moons, and scientists believe a saltwater ocean may exist beneath its icy crust.
