Ellison is a lunar impact crater that lies on the far side of the Moon from the Earth. It is located just beyond the northwest limb of the Moon, to the southwest of the large Poczobutt walled-plain. Due west of Ellison is the Coulomb crater. The outer rim of Ellison is roughly circular, with an inward protrusion along the southern rim and a slight outward bulge to the wet-northwest. It has a single terrace on the northeastern inner wall, formed from the slumping of material. Instead of a central peak, there is a small crater located at the mid-point. A smaller crater is located just to the west-southwest of this centrally-located formation, but the flat interior floor is otherwise devoid of features of interest.
Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Ellison crater.
