Saturn's moon Rhea looms "over" a smaller and more distant Epimetheus against a striking background of planet and rings.
The two moons aren't actually close to each other. The view was obtained at a distance of approximately 1.2 million kilometers (746,000 miles) from Rhea and 1.6 million kilometers (994,000 miles) from Epimetheus.
Lit terrain seen here is in the area between the trailing hemisphere and anti-Saturn side of Rhea (1,528 kilometers, or 949 miles across). Lit terrain seen on Epimetheus (113 kilometers, or 70 miles across) is mostly on the Saturn-facing side. This view looks toward the sunlit side of the rings from just above the ringplane.
The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on March 24, 2010. Image scale is 7 kilometers (4 miles) per pixel on Rhea and 10 kilometers (6 miles) per pixel on Epimetheus.
