Petrov is a lunar crater along the southeastern limb of the Moon. The crater is difficult to observe in this location, and visibility of this feature is affected by libration. The nearest crater of note is Chamberlin, just on the far side to the northeast. Somewhat further to the west-southwest of Petrov is Gill crater.
The rim of this crater has been worn and eroded by impacts, leaving an irregular ring of ridges and incisions along the inner wall. The smaller crater 'Petrov A' is intruding slightly into the southern rim. Along the southeast, 'Petrov B' is attached to the southeastern exterior and the two are joined by a narrow valley.
The interior floor of Petrov has been completely resurfaced by basaltic-lava, leaving a low albedo surface that is relatively smooth and featureless. This material is nearly as dark as the Mare Australe lunar mare to the north. The floor is marked only by a few tiny craterlets.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Petrov crater.
