Crater morphology and morphometry on the Uranian satellites

Abstract

Fresh craters on the icy Uranian satellites exhibit a range of morphologies similar to craters on the icy satellites of Jupiter and Saturn. The general structural features found in the craters are described. Estimates of transition diameters from simple to complex crater morphologies are given for the five large Uranian satellites and 1985U1, and plotted with transition diameters on other bodies against surface gravity. Possible large-scale impacts are discussed
