Carpenter is a lunar impact crater that is located in the northern part of the Moon, relatively close to the limb. At this position the crater is forshortened and appears oval in shape. It is, however, very nearly circular in outline. The outer rampart to the south is adjoined to the old Anaximander crater, and the satellite formation 'Anaximander B' lies along the western rim. To the northeast is the Anaximenes crater.

In geological terms this is a somewhat young lunar crater, with features that have not been significantly eroded by subsequent impacts. Certainly it is much younger than the surrounding crater formations. The inner wall displays an appearance of slumping, particularly along the eastern face, and there is some development of terraces. The outer rim is unmarked by craterlets of note, but there is a small crater along the south-southeastern inner wall.

The interior floor within the slopping inner walls is generally level, but irregular with many small bumps and hills. Near the mid-point is an unusual double central peak formation, with a smaller peak offset to the west and a larger ridge offset to the east. The later ridge runs southward to the edge of the inner wall.

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 Carpenter crater.
