Sol/Ganymede

Ganymede is the largest moon of Jupiter and the largest moon in Sol. It has a bigger diameter than Mercury, but half its mass. It was first discovered by Galileo Galilei in 1610.^[1]

Beneath the frozen surface of Ganymede is a saltwater ocean which could be habitable to life. It contains more water than all oceans on Earth.^[2]
