Proctor is the remnant of a lunar crater that is located to the southeast of the prominent Tycho crater. It lies just to the north of the huge Maginus walled plain. To the north is Saussure crater and to the northwest, just to the east of Tycho, lies Pictet crater. It is 52 kilometers in diameter and its walls are 1,300 meters high. It is from the Pre-Imbrian period, which lasted from 4.55 to 3.85 billion years ago."Autostar Suite Astronomer Edition". CD-ROM. Meade, April 2006.] [cite web

The outer rim of this crater has become heavily worn and eroded, and now forms a low, irregular rise around the interior floor. Much of the northwestern half of the rim is marked by a number of small craters, including 'Proctor D'. The interior floor is somewhat level and is marked only by a few tiny impacts. [cite book
