Unformatted text preview: Figure 3: View of Enceladus's orbit from the side, showing Enceladus in relation to Saturn's E ring Enceladus orbiting within Saturn's E ring There are actually two distinct mechanisms feeding the ring with particles.  The first, and probably the most important, source of particles comes from the cryovolcanic plume in the South polar region of Enceladus. While a majority of particles fall back to the surface, some of them escape Enceladus's gravity and enter orbit around Saturn, since Enceladus's escape velocity is only 866 km/h. The second mechanism comes from meteoric bombardment of Enceladus, raising dust particles from the surface. This mechanism is not unique to Enceladus, but is valid for all Saturn's moons orbiting inside the E Ring....
