Eponym	Wilhelm W. Beer

Beer is a relatively small lunar impact crater located on the Mare Imbrium, to the east of the crater Timocharis. It was named after German astronomer Wilhelm W. Beer.^[1] Just to the northwest is the matching twin Feuillée.

Beer is a circular, cup-shaped crater with a sharp-edged rim that has not been significantly eroded. The interior has a higher albedo than the surrounding lunar mare, which is usually an indication of a relatively young crater. A string of craters arc away from the rim to the southeast, which then grade into a straight rille, and were once known as Fossa Archimedes or Archimedes Rille, but now are officially unnamed.

The mare to the east has a higher albedo than the surrounding surface, and this lighter-hued surface reaches to the base of the Montes Archimedes. To the southeast of Beer is a lunar dome that is of comparable diameter to the crater.
