Prometheus
Voyager 2 color image showing the shepherding satellite Prometheus (1980S27) and part of the F-ring against the background of Saturn. The A-ring and Encke gap are also visible at upper left. Prometheus orbits at a distance of 139,350 km from Saturn and is about 40 x 70 km in size. The satellites brightness suggests it is an icy body like the larger satellites and ring particles.
