Saturn's Moon Tethys

Tethys, one of Saturn's larger moons, is made almost entirely of water ice. Both Voyager spacecraft visited Tethys, revealing a massive impact crater that nearly circles the moon. The fact that this impact did not shatter Tethys suggests it was not completely frozen in its past. Tethys has two smaller moons, Telesto and Calypso, that share its orbit.
