Dione - Voyager 1

Saturn's satellite Dione from 620,000 km

Dione
Distinctive albedo patterns on the trailing hemisphere of Saturn's 1120 km diameter satellite, Dione, are shown in this Voyager 1 image. This portion of Dione appears fresh and smooth, in sharp contrast to the heavily cratered area on the Saturn-facing portion of the leading hemisphere. The north pole is at 1:00 on the edge of the disk. This image was taken from a distance of 620,000 km and has a resolution of 5 km/pixel. (Voyager 1, FDS 34933.38)
