Aristillus is a prominent lunar impact crater that lies in the eastern Mare Imbrium. Directly to the south is the smaller crater Autolycus while to the southwest is the large Archimedes. The area of mare to the southwest is named the Sinus Lunicus. To the northeast are the craters Theaetetus and Cassini.The rim of Aristillus has a wide irregular outer rampart of ejecta that is relatively easy to discern against the smooth surface of the surrounding mare.
