Bunsen is a lunar impact crater that lies near the northwestern limb of the Moon.

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.

Within the crater, the floor is pitted by tiny impacts, and has a fracture system[1] of criss-crossing clefts near the northern and southern rims.

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