Rhea: Saturn's Second Largest Moon

Rhea is Saturn's second largest moon, behind Titan, and the largest without an atmosphere. It is primarily composed of water ice, with a small rocky core. Like Earth's Moon, Rhea is tidally locked with Saturn, always showing one face to the planet. Its leading hemisphere is much more heavily cratered than its trailing side, as seen in this 1980 image from Voyager 1.
