This montage of images of the Saturnian System
was prepared from an assemblage of images taken by the Voyager
1 spacecraft during its Saturn encounter in November 1980. This
artist's arrangement shows Dione in the forefront, Saturn rising
behind, Tethys and Mimas fading in the distance to the right,
Enceladus and Rhea off Saturn's rings to the left, and Titan in
its distant orbit at the top. With a diameter of 5150 km (3200
mi), Titan is by far the largest of the Saturn satellites and
is the only moon in the Solar System with an Earth-sized atmosphere.
Heavily cratered Rhea, whose diameter is 1530 km (950 mi), is
Saturn's second largest satellite. Tethys and Dione are about
1100 km (680 mi) in diameter. 500-km (310-mi) Enceladus may be
the source of the tiny ice particles which form Saturn's tenuous
E ring. 392-km (244-mi) Mimas, with the enormous crater Herschel
on one side, has an appearance reminiscent of the Death Star in
the movie "Star Wars." (P-23209)
