Petropavlovskiy (crater)

Petropavlovsky is a crater on the far side of the Moon. It is attached to the southern rim of the slightly larger crater Razumov, intruding slightly into the interior. Just to the west is the crater Frost, along the southern rim of the walled plain Landau.

This is a moderately eroded feature, with a worn outer rim that is marked by several lesser impacts. A merged pair of small craters cuts across the northwestern rim and inner wall, and another craterlet lies along the southeast rim. The interior floor is relatively level, except for a double central peak formation at the midpoint.
