Rhea

Original caption:"Scarred and battered Rhea fills the Cassini spacecraft's view. Notable here is the sharp relief of steep crater walls near the terminator.
Icy Rhea (1.528 Km --> 949 miles across) is Saturn's second-largest moon. This view shows terrain on Rhea's Trailing Hemisphere. North is up and rotated 22° to the left.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Dec. 24, 2005 at a distance of approximately 267.000 Km (such as 166.000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 59°. Image scale is 2 Km per pixel".
