Explanation:
Rhea is the second largest moon of
Saturn, behind Titan, and the largest without an atmosphere.
It is composed mostly of water
ice, but has a small rocky core.
Rhea's rotation and orbit are locked together
(just like
Earth's Moon)
so that one side always faces Saturn.
A consequence of this is that one side always leads the other.
Rhea's leading surface is much more heavily
cratered than its trailing surface.
The

Voyager 1 spacecraft in 1980.
