Named after Dmitrij Dmitrievich Maksutov - Soviet optician (1896-1964).
Maksutov is a crater on the far side. It is located just to the south-southwest of the larger walled plain Oppenheimer. To the southwest lies the crater Nishina, and to the west-northwest is the merged crater pairing of Davisson and Leibnitz. This crater has a reasonably well-defined outer rim that has not been significantly degraded through impact erosion. (wikipedia entry)
A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
