Saturn's F Ring

May 25, 2000
Saturn's F, or outermost ring was photographed from the un-illuminated face of the rings by NASA's Voyager 1 at a range of 750,000 kilometers (470,000 miles).

Saturn's F, or outermost ring was photographed from the un-illuminated face of the rings by Voyager 1 at a range of 750,000 kilometers (470,000 miles). Complex structure is evident, with several components seen. Two narrow, braided, bright rings that trace distinct orbits are evident. Visible is a broader, very diffuse component about 35 kilometers (20 miles) in width. Also seen are "knots," which probably are local clumps of ring material, but may be mini-moons. The Voyager Project is managed by the Jet Propulsion Laboratory for NASA.
