Geological Chronicle

Tikhov is an eroded impact crater measuring 83.97 kilometers across on the Moon's far side. It is nearly attached to the east-southeastern outer rim of the larger crater Avogadro. About one crater diameter to the east-northeast lies the equally worn crater Emden, and to the south-southeast lies the younger Tsinger. The crater commemorates Soviet astronomer Gavriil Adrianovich Tikhov.

The formation dates to the Nectarian period on the lunar geologic timescale. Subsequent impacts have battered the structure, leaving smaller craters along its rim, inner wall, and floor, including several recent cup-shaped craters along the eastern side. This wear has left the outer rim rounded and uneven, though its circular outline remains visible.
