Description

Aristillus and Autolycus – two prominent craters in the southeast of Mare Imbrium. Aristillus is the northern-most of the pair at 55-km-wide and has a wide outer rampart of ejecta and a ray system that extends up to 600 km from the crater. Crater depth is 3600m. The three clustered peaks in the centre of the crater rise to 0.9 km elevation above crater floor.

Just north of Aristillus and just under its northern rampart lies a ghosted crater remnant, the protruding rim of an older crater that has been almost completely flooded by lava flows of Mare Imbrium, with the southern end of the rim covered by ejecta from Aristillus.

South of Aristillus lies Autolycus of Copernican age.
