, and the ejecta from Finsen covers the southeastern part of Leibnitz's interior floor. To the southwest of Finsen is another walled plain, Von Kármán, partly overlain by Leibnitz. This is a relatively young impact crater with well-defined features that have not been significantly eroded by subsequent impacts. The rim is circular but somewhat uneven along the edge, with outward protrusions along all sides except to the north and northwest. The inner wall has slumped in places, producing a sharp rim edge in the southern half. There are also a number of short

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