Rhea: Craters
built 628 days ago
Rhea is the largest of Saturn's medium-sized icy moons. From a distance, Rhea looks similar to Tethys with its wispy grooves and flat-floored craters. Close up, Rhea shows itself one of the most heavily cratered places in the Solar System. Its craters tend to be polygonal in shape, having straighter rather than curved sides, possibly indicating the orientations of preexisting fractures in Rhea's outer crust that are too fine to see in currently available images. Features on Rhea are named for people and places from creation myths around the world.

Rhea, the fifth major satellite of Saturn, may be one of the most heavily cratered satellites in the solar system. Its surface appears to be saturated with craters, but long, bright linear features can be seen on the trailing hemisphere and linear ridges can be seen in the leading hemisphere. These ancient features may record changes in Rhea's shape due to internal heating or cooling.

This view of the trailing hemisphere of Saturn's moon Rhea shows the region's bright wispy markings, but ... shows off the moon's craters in great detail. Of particular interest to imaging scientists is the distribution and orientation of the many craters with polygonal rims. These are craters with rough, angular shapes, rather than smooth, circular ones. Rhea is 1,528 kilometers (949 miles) across.

This stereo view of a portion of Rhea reveals the heavily cratered terrain of this small satellite. No smooth areas can be seen between the innumerable craters. If Rhea ever was volcanically active, this must have occurred very early in its history and any record obliterated by repeat impact cratering.

In the nick of time, the Cassini spacecraft snapped this image of the eastern rim of Saturn's moon Rhea's bright, ray crater. The impact event appears to have made a prominent bright splotch on the leading hemisphere of Rhea (see PIA06648). Because Cassini was traveling so fast relative to Rhea as the flyby occurred, the crater would have been out of the camera's field of view in any earlier or later exposure.
