Mimas, Rhea and the Rings

Original caption:"The Saturn moon Mimas is much smaller than Rhea, but the geometry of this scene exaggerates the actual differences in size. Here, Mimas is on the opposite side of the rings from Rhea and Cassini. Saturn's shadow slices across the Ring-plane here.
The view looks toward the Saturn-facing hemisphere on Mimas and the anti-Saturn hemisphere on Rhea.

The image was taken in visible light with the narrow-angle camera on Sept. 9, 2005, from a distance of approx. 1,5 MKM (about 900.000 miles) from Rhea. Mimas was located on the far side of the Rings, such as about 670.000 Km (approx. 420.000 miles) farther from Cassini. The image scale is roughly 9 Km (about 6 miles) per pixel on Rhea and 13 Km (about 8 miles) per pixel on Mimas".
