Document Summary
Extends much further than the other rings. Almost all of them show evidence of past volcanism and/or tectonics. Craters: surface that hasn"t changed much recently. Also see evidence of tectonic plate movement. Ice fountains of enceladus suggest it may have a subsurface ocean. Southern pole: emissions of water and other hydrogen compounds (geysers) Tidal heating creates a localized region of warm water in the southern hemisphere. Moon is bombarded by ions and electrons that may interact with surface and generate a different source of heat. Large tectonic features and few craters (indicating an episode of tidal heating in the past) Neptune on the edge of the kuiper belt (region where comets form) Goes around neptune in the opposite way than the rotation of neptune (were not part of the same system when they formed) Could be an actual object of the kuiper belt (likely that some of these objects can get close enough to be captured)
