Enceladus is one of Saturn's intermost moons. It shows five different types of terrain including fissures, plains, corrugated terrain and other crustal deformations. There are also parts that show craters no larger than 35km in diameter and some regions display no crater impact at all. This indicates major resurfacing events in Enceladus's recent geological past. All of these landforms indicate that the interior of Enceladus my be water today even though it should have frozen aeons ago. Enceladus's orbit is disturbed by neighboring satellites, Dione and Tethys and Saturn's gravitational field.(picture: Enceladus is the brightest moon that is above the rings in the picture)
