Callisto
MOON · orbits Jupiter
A dark, quiet ice ball whose face is completely covered in craters, more than any other world we know. Nothing has resurfaced Callisto for about four billion years, so it is like a museum of the early solar system. Because it orbits outside Jupiter's worst radiation, people dreaming about future bases in the Jupiter system often pick Callisto.
