Mimas and Dione from Cassini
MOONS IN PERSPECTIVE
--------------------
Two of Saturn's battered, icy companions hover here in this Cassini image,
above the planet's ringplane. To get a sense of the three-dimensional
nature of the scene, note that the wide band of visible rings is in
between the two moons in this view. Mimas is outside the far side of the
rings. Dione is outside the rings and closest to Cassini.
