Two satellites of Saturn share an orbit 151,400 kilometers (94,075 miles) from the center of the planet. The leading co-orbital satellite, designated 1980S1, is seen in transit across Saturn in this image taken by NASA's Voyager 1 on Nov. 12, 1980, at a range of 611,000 kilometers (379,650 miles). It is ellipsoidal, almost disk-shaped, and rotates with its long axis, 200 kilometers (125 miles) in diameter, pointed at Saturn. The Voyager project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.
