Beketov is a small lunar impact crater that lies in the northern reaches of the Mare Tranquillitatis.[2] It is a relatively fresh, cup-shaped feature with a circular rim and inner walls that slope down to a central floor.[3] A pair of irregular lunar domes lie to the north.[4] To the south is the ghost crater Jansen R. Northeast of Beketov, along the edge of the mare, is the crater Vitruvius.[3]

This crater is named after Russian chemist Nikolay Beketov (1827–1911). It was previously designated Jansen C before this Beketov was formally adopted by the International Astronomical Union in 1976.[1] The flooded crater Jansen lies to the south.[3]
