Diameter	52 km
Depth	Unknown
Colongitude	86° at sunrise
Eponym	Robert W. Bunsen

Bunsen is a lunar crater that lies near the northwestern limb of the Moon. It is located to the west of the Oceanus Procellarum and the von Braun crater. To the southeast is Lavoisier crater, and to the northeast lies Gerard crater. Northwest of Bunsen, on the far side of the Moon, is McLaughlin crater. Due to its position this crater appears foreshortened when viewed from the Earth, and its visibility is affected by libration.

This crater has become considerably worn and eroded by subsequent impacts, leaving a formation that has been described as disintegrated. The most intact portion of the rim is along the northeastern side. There is a smaller, crater-like formation intruding into the southeastern rim. Within the crater, the floor is pitted by tiny impacts, and has a rille system of criss-crossing clefts near the northern and southern rims. There is a low ridge near the southwest corner of the interior.

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 Bunsen crater.
