Enceladus

Enceladus (pronounced /ɛnˈsɛlədəs/) is the sixth-largest moon of Saturn. It is approximately 500 kilometers (310 mi) in diameter, about a tenth of that of Saturn's largest moon, Titan. Enceladus is mostly covered by fresh, clean ice, reflecting almost all the sunlight that strikes it, making its surface temperature at noon reach only −198 °C (−324.4 °F). Despite its small size, Enceladus has a wide range of surface features, ranging from old, heavily cratered regions to young, tectonically deformed terrains that formed as recently as 100 million years ago.
