Saturn QuintetFive Saturn moons seem to gather near the gas giant's rings for a group portrait in a new picture from NASA's Cassini orbiter released September 12. Saturn's second largest moon, Rhea, is closest to the spacecraft and is bisected by the right edge of the frame. Just beyond, from right to left, are the smaller moons Mimas, Enceladus, Pandora, and Janus.(Also see "Saturn Moon Has Oxygen Atmosphere.")
