Brunner is a lunar impact crater that is located along the eastern limb of the Moon, to the southeast of the Mare Smythii. At this location the crater is viewed from the edge, and so it is not possible to see much detail from the Earth. The visibility of this formation is also affected by libration. The crater lies to the southwest of the walled plain Hirayama, and to the east of the elongated crater Houtermans.
The rim of Brunner is well-defined and nearly circular, although there is a slight outward bulge and a depressed wall along the north. The interior of the crater is rugged and irregular, with a central ridge formation at the midpoint. There is also a ring-like formation on the floor that is concentric with the inner wall.
