Tannerus is a small lunar crater that is located in the rugged southern highlands of the Moon. It lies within a couple of crater diameters of Asclepi crater to the northeast, and some distance due east of Jacobi crater.

The rim of this crater is very close to circular, with only a slight inward bulge along the north edge where it is joined to 'Tannerus P'. The edge is sharp and well-defined, although there are tiny impacts along the rim in the west and south. The crater floor is level and free of markings or features of note.

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 Tannerus crater.
