Ganymede

Ganymede (Jupiter III) is a seventh moon of Jupiter. With a diameter of 5,268 km. it is 8% larger than Mercury (but has only 45% of its mass) and 2% larger than Titan. Ganymede is probably composed of approximately equal amounts of silicate rock and water ice. A saltwater ocean is believed to exist nearly 200 km beneath its surface, sandwiched between layers of ice.

The possibility that it might be habitable has drawn recent attention from scientists.
