This view of Tethys is a color composite of three images taken by Voyager 2 on August 25, 1981 from a range of 594,000 kilometers (368,000 miles). Tethys' surface is composed of densely cratered regions and a lightly cratered, dark belt that extends across the satellite. Light cratering indicates that the region was once internally active early in Tethys' history and resurfaced part of the older terrain. Ithaca Chasma, an enormous trench that is 65 kilometers (40 miles) wide and several kilometers deep, runs parallel to the terminator at the right.
