Ellison is a lunarimpact 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 walled plain Poczobutt. Due west of Ellison is the crater Coulomb.
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 midpoint. 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.
