Enceladus 

Discovered by William Herschel in 1789, Enceladus is one of the innermost moons of Saturn. Enceladus is a smooth and bright satellite relative to Mimas and has a high albedo due to its high >reflectivity.

The surface temperature of Enceladus is -201° C (-330° F) and has a diverse surface, with all sorts of features that tell much about its history. There are cratered nd non-cratered plains, many crustal deformations with fissures and rough terrain. The interior may be liquid although this goes against common logic because its low surface temperature would prohibit the formation of ice. However it is theorized that Enceladus is warmed by a tidal mechanism.
