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.
