Image of the Day: Saturn & Its Moons

S18_00152609
 

Saturn's moons Rhea orbits near Epimetheus in this Cassini image with the planet and its rings in the background. The two moons aren't actually close to each other. The view was obtained at a distance of approximately 1.2 million km (746,000 mi) from Rhea and 1.6 million km (994,000 mi) from Epimetheus. The image was taken on March 24, 2010. Of Saturn's seven moons that are large enough to become spherical, and dense rings with complex orbital motions of their own, most notable are Titan, the second-largest moon in the Solar System, with an Earth-like atmosphere and a landscape including hydrocarbon lakes and dry river networks, and Enceladus, which emits jets of gas and dust and may harbor liquid water under its south pole region.
