Abstract
A topographic model of Saturn's smaller co-orbital satellite Epimetheus was derived from the shapes of limbs, terminators and shadows of the F Ring in Voyager images, modified locally to accommodate large craters and ridges. The model is presented here in tabular and graphic form, including the first detailed shaded relief maps of the satellite. The shape is approximated by a triaxial ellipsoid with axes of 144, 108 and 98 km. The volume is estimated to be 8 ± 1 × 105 km3. A prominent valley and several grooves are found on the heavily cratered surface.
