Coordinates	36.2° S, 67.9° W
Diameter	101 km
Depth	2.3 km
Colongitude	70° at sunrise
Eponym	Giuseppe Piazzi

Piazzi is a lunar crater that is located near the southwestern limb of the Moon, and is attached to the southeast rim of the Lagrange walled plain. About three crater diameters to the south is the Inghirami crater. Piazzi crater is observed at a low angle from the Earth, and it appears oblong due to foreshortening.

As with Lagrange, this formation has been heavily modified by the ejecta from the formation of the Mare Orientale impact basin to the northwest. This material has formed radial valleys and ridges across the surface of these craters. The interior floor of Piazzi has dark patches of low albedo along the northeastern rim. The outer rim of the crater is irregular and eroded, and a few small craters lie within the uneven interior.

[edit] Satellite craters

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 Piazzi crater.
