Named after Georgii Sergeevich Zhiritskiy - Soviet rocketry scientist (1893-1966).
Zhiritskiy is a lunar crater on the far side. It lies to the south of the large walled plain Fermi, and northwest of the crater Schaeberle. This crater lies across the western rim of the much larger satellite crater Zhiritskiy F, a circular, eroded formation. Zhiritskiy is slightly elongated, having a minor protrusion in its outer rim toward the east. (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.
