Gibbous Rhea (Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)

Caption NASA:"The Cassini Spacecraft looks toward the cratered plains of the Trailing Hemisphere of Rhea.
Some of the moon's fractures, appearing like wispy bright lines, can be seen on the left of the image. Rhea's North Pole is up and rotated 3° to the right.
This Celestial Body is about 1528 Km (approx. 949 miles) across.

The image was taken in Visible Light with the Cassini Spacecraft wide-angle camera on Nov. 21, 2009. The view was obtained at a distance of approx. 30.000 Km (about 19.000 miles) from Rhea and at a Sun-Rhea-Spacecraft, or Phase, Angle of 27°.
Image scale is roughly 2 Km (a little more than 1 mile) per pixel.
