Reimarus is a lunar impact crater, located in the southeastern part of the Moon's near side. The eroded southeastern end of the long Vallis Rheita (Rheita valley) passes just to the west. To the northeast is the larger and heavily worn crater Vega.
This is a heavily worn and eroded crater, with an outer rim that has been incised and battered by multiple lesser, later impacts, particularly in the western half. Several small craterlets lie along the rim edge and the inner walls, and the outer rise is generally uneven and rugged. On the southwest part of the interior floor is a small crater. The remainder of the floor is generally featureless and marked only by a few tiny craterlets.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Reimarus.

Ewen Adair Whitaker was a British-born astronomer who specialized in lunar studies. During World War II he was engaged in quality control for the lead sheathing of hollow cables strung under the English Channel as part of the "Pipe Line Under The Ocean" Project (PLUTO) to supply gasoline to Allied military vehicles in France. After the war, he obtained a position at the Royal Greenwich Observatory working on the UV spectra of stars, but became interested in lunar studies. As a sideline, Whitaker drew and published the first accurate chart of the South Polar area of the Moon in 1954, and served as director of the Lunar Section of the British Astronomical Association.
