Tikhov (lunar crater)
Tikhov is an eroded lunar impact crater 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 the east-northeast of Tikhov is the equally worn crater Emden, and to south-southeast lies the younger Tsinger.

This feature has been battered by subsequent impacts, leaving a series of smaller craters along the rim, inner wall, and floor of the crater. The most recent of these impacts are several small, cup-shaped craters along the eastern rim and inner wall and floor. As a result of this wear, the outer rim is rounded and uneven, although the circular nature of the rim can still be discerned.
