Piazzi (crater)

Piazzi is an impact crater that is located near the southwestern limb of the Moon, and is attached to the southeastern rim of the walled plain Lagrange.

Piazzi is seen at an oblique angle from the Earth, and it appears oblong due to foreshortening.

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.

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