Saturn's Satellite Iapetus from 910,000 km

Iapetus
Voyager 2 image of Saturn's satellite Iapetus from 910,000 km. The north pole is just to the left of the terminator, about one-quarter of the way from the bottom of the disk. Near the pole, right on the terminator, is the 144 km diameter crater, Roland, centered at 73 N, 25 W. This lighted portion of Iapetus is the side facing away from Saturn. The dark Cassini Regio can be seen at the extreme left. Iapetus is 1450 km in diameter, and this image has a resolution of 8 km/ pixel. (Voyager 2, FDS 43913.35)
