Pitatus is an ancient lunar impact crater located at the southern edge of Mare Nubium.

Pitatus is a floor-fractured crater, meaning it was flooded from the interior by magma intrusion through cracks and openings.

The flooded crater floor contains low hills in the east and a system of slender clefts named the Rimae Pitatus.

The larger and more spectacular of these rilles follow the edges of the inner walls, especially in the northern and eastern halves.

[2] By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Pitatus.
