The Runners in the Ring: Prometheus and Pandora

This spectacular image shows Prometheus (at left) and Pandora (at right), with their flock of icy ring particles (the F-Ring) between them. Pandora is exterior to the Ring, and closer to the spacecraft here. Each of the shepherd satellites has an unusual shape, with a few craters clearly visible.
The effect of Prometheus (about 102 Km across) on the F-Ring is visible as it pulls material out of the Ring when it is farthest from Saturn in its orbit. Pandora is about 84 Km across.

The image was taken in polarized green light with the Cassini spacecraft narrow-angle camera on Oct. 29, 2005, at a distance of approx. 459.000 Km (about 285.000 miles) from Pandora and 483.500 Km (roughly 300.500 miles) from Prometheus. The image scale is 3 Km (about 2 miles) per pixel on Pandora and 3 Km (idem) per pixel on Prometheus. The view was acquired from about 1/3 of 1° below the Ring-Plane.
