eponym=Daniel Kirkwood Kirkwood is a well-formed lunar
impact crater that is located on the far side of theMoon , on the northern hemisphere. It lies just to the northeast of the Sommerfeld crater, and Hippocrates crater is located to the east-northeast.The perimeter of this crater is generally circular, with a few slight outward knotches particularly to the southeast. It displays vely little appearance of wear, and neither the interior nor the outer are marked by any craters of note.
The inner wall has slumped somewhat, and has formed a few -like structures. The interior "ejecta" spreads a good way across the inner floor, covering nearly half the diameter. At the mid-point appear several small hills producing a central peak formation.

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 Kirkwood crater.
