Named after Nikolaj Aleksandrovich Morozov - Soviet natural scientist (1854-1945).
Morozov is a lunar impact crater on the far side. It lies to the north of the crater Gregory, and to the east-southeast of Ibn Firnas. Less than two crater diameters to the west-southwest is Zanstra. This is a worn and eroded crater formation, particularly along the western rim where a pair of parallel marks cross the inner wall, running to the south-southeast. (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.
