Cook is a lunar impact crater that lies in the western part of the Mare Fecunditatis. This formation is easy to spot due to its dark floor.[2] To the northwest of Cook is the prominent crater Colombo. To the southwest is Monge.[3]

The interior of this crater has been flooded with lava, leaving only a low rim projecting above the surface. This rim is not quite circular, and has a somewhat hexagonal appearance. The low wall is worn in a few places, particularly along the northeastern rim. There is a small crater called Cook A on the interior floor near the southeast rim.[4]: 97 

This formation is named after British explorer James Cook (1728–1779). His name was included with the lunar nomenclature of German astronomer Johann Heinrich von Mädler in the 19th century.[5] Its designation was formally adopted by the International Astronomical Union in 1935.[1]

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Cook.[6]
