Kurzfassung
With a mean diameter of 1528 km, Rhea is the second-largest satellite of Saturn. The low average density of 1.233 g cm<sup>-3</sup> and water ice absorption bands imply that Rhea's interior and its surface are dominated by water ice. Rhea was imaged by the cameras aboard the Cassini Orbiter at spatial resolutions up 10 m/pxl. Rhea's surface is charaterized by densely cratered plains dating back to a period of at least 4.2 billion years ago. Oldest features in the cratered plains are impact basins several 100 km in diameter. Cassini ISS has revealed tectonic features indicative of extensional, compressional and shear stresses which possibly were active prior to 3 billion years ago. One of the youngest features found on Rhea is a bright crater, about 48 km in diameter, with an extended system of bright rays. The butterfly wing pattern of these ejecta suggest an oblique impact from the east.
