Karl Schwarzschild Karl Schwarzschild (; 9 October 1873 – 11 May 1916) was a German physicist and astronomer. Schwarzschild provided the first exact solution to the Einstein field equations of general relativity, for the limited case of a single spherical non-r ...

(1873–1916). The somewhat irregular outer rim of Schwarzschild has been overlain by many smaller impact craters, including most notably Schwarzschild K across the southeastern face and Schwarzschild D on the northeastern rim. The rim is roughly circular in form, with an outward bulge along the southwestern side. The rim has been softened and modified by impact erosion, particularly to the northeast. Just to the northeast of Schwarzschild K is a short chain of small craters lying across the rim and inner wall of Schwarzschild. The inner floor of Schwarzschild is relatively level by comparison with the rugged terrain outside, and is particularly flat in the north-northeastern half. There is a region of low, irregular ridges to the west of the midpoint. Lying in the southeastern part of the floor is the satellite crater Schwarzschild L, and surrounding this interior crater is an outer

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