Object guide
Enceladus ejects water-rich plumes from a subsurface ocean through fractures near its south pole. The plumes supply material to Saturn's E ring and indicate conditions that may be habitable in its ocean. Enceladus is approximately 504.2 km across.
How to observe Enceladus
Enceladus is resolved as a separate world mainly through imaging or spacecraft data; visually, its relationship to saturn is the key observing context.
Scientific context
Useful scale comparisons are 0.04 Earth diameters, 0.012 g surface gravity, 0.004 Earth years per orbit. These values are rounded from the catalogue measurements shown on this page.
