PIA01974: Cratered Surface of Tethys

Cratered Surface of Tethys


The heavily cratered surface of Tethys was photographed at l:35 a.m. PST on November 12 from a distance of l.2 million kilometers (750,000 miles) by Voyager l. This face of Tethys looks toward Saturn and shows a large valley about 750 kilometers long and 60 kilometers wide (500 by 40 miles). The craters are probably the result of impacts and the valley appears to be a large fracture of unknown origin. The diameter of Tethys is about 1000 kilometers (600 miles) or slightly less than l/3 the size of our Moon. The smallest feature visible on this picture is about 24 kilometers across.
