Dione
Dione was discovered by G. Cassini in 1684. Dione is the 7th farthest moon from Saturn, with a standoff distance of 377,400 km. It is a small
icy moon, lightly cratered, with wispy white streaks across the
surface. Dione is about as wide as the Oregon coast is long, a width of 1120 km, or 750 miles. In appearance, it looks very much like
Rhea,
Enceladus, and
Tethys.
