Rhea (MULTISPECTRUM; credits: Lunexit)

Caption NASA:"The Cassini Spacecraft surveys the stark beauty of Saturn's moon Rhea.
Rhea's North Pole is up and tilted slightly away from Cassini in this view; the moon's south pole is in sunlight at bottom. Lit terrain seen here is on the Anti-Saturn Side of Rhea.

The image was taken in visible red light with the Cassini Spacecraft narrow-angle camera on June 10, 2008. The view was acquired at a distance of approx. 420.000 Km (approx. 261.000 miles) from Rhea and at a Sun-Rhea-Spacecraft, or Phase, Angle of 53°.
Image scale is roughly 3 Km (about 2 miles) per pixel".
