To the north is the crater Saussure and to the northwest, just to the east of Tycho, lies Pictet.

Proctor is 52 kilometers (32 mi) in diameter and its walls are 1,300 meters (4,300 ft) high.

[1][2] The outer rim of this crater has become heavily worn and eroded, and now forms a low, irregular rise around the interior floor.

[3] The crater is named after the 20th-century American astronomy writer Mary Proctor.

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