The rim of Bayer is slightly worn by erosion, but remains well-defined. There is an inner terrace, but the outer wall is intruded upon by nearby impacts. The most significant of these is Schiller H, which forms a ridge attached to the northwest rim of Bayer. The floor of Bayer is relatively flat and lacks a central peak. There is a small, but notable crater on the floor near the western wall. This crater has a breach in its northern rim. Satellite cratersBy convention these features are identified on Lunar maps by placing the letter on the side of the crater midpoint that is closest to Bayer.
