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 (102 kilometers, or 63 miles 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 84 kilometers (52 miles) across.
