Prometheus and Pandora are seen here shepherding Saturn's narrow F ring. Prometheus (86 kilometers, 53 miles across) overtakes Pandora (81 kilometers, 50 miles across) in their orbits around Saturn about every twenty-five days. Slightly above the pair and to the right is Epimetheus (113 kilometers, 70 miles across). The image was taken with the narrow angle camera on May 1, 2004 at a distance of 31.4 million kilometers (19.5 million miles) from Saturn. Image scale is 187 kilometers (116 miles) per pixel. The image has been magnified and greatly contrast-enhanced to aid visibility.
