Prometheus (at right) and Pandora (at left), 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 km, or 63 mi 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 km (52 mi) across.
The image was taken at a distance of approximately 459,000 km (285,000 mi) from Pandora and 483,500 km (300,500 mi) from Prometheus. The image scale is 3 km (2 mi) per pixel on Pandora and 3 km (2 mi) per pixel on Prometheus. The view was acquired from about a third of a degree below the ringplane.
