South on Rhea
The Cassini spacecraft surveys the south polar region of icy Rhea.
This is a similar view to Above Rhea's South Pole. This view is a bit farther south and has slightly different solar illumination.
Cassini flybys have shown that Rhea is not differentiated, or separated into distinct layers; instead, it appears to be a mixture of approximately 75 percent ices and 25 percent rock and metal.
Saturn's second-largest moon, Rhea is 1,528 kilometers (949 miles) wide.
The image was taken with the Cassini spacecraft narrow-angle camera on April 12, 2008 using a spectral filter sensitive to wavelengths of ultraviolet light centered at 338 nanometers. The view was acquired at a distance of approximately 345,000 kilometers (214,000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 73 degrees. Image scale is 2 kilometers (1 mile) per pixel.
