Enceladus is the sixth largest moon of Saturn, only about 1/10th the size of Titan. However, it is of great interest due to its icy surface, geologic activity, and potential subsurface ocean. It is similar to Europa in several respects, being an icy satellite of a gas giant hypothesized to contain a liquid water ocean, but it may be superior given the lower radiation and potentially much thinner ice layer.
