Tarpeia has a diameter of 41 km. It is irregularly shaped and has a sharp, fresh rim. It contains many small craters less than a kilometer across and its steep slopes shows brilliant layers of minerals. (wikipedia entry)
A crater is a circular depression likely created by an impact event. On Vesta they are named after names historically associated with the Roman goddess Vesta (vestal virgins, people associated with vestal virgins) and famous Roman women.
