An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters ...

. To the northwest of Zeeman lies the crater
Numerov. Southeast of the rim is the crater
Ashbrook.
The outer rim of Zeeman is eroded somewhat irregularly, with considerable variation in width of the inner slopes. The crater Zeeman Y lies across the northern wall, reaching almost to the relatively flat interior floor. In the western rim is a small crater that joins a gash that runs down to the floor. The surface of the interior is pock-marked by many tiny craterlets, and worn crater features. There is a low central rise, offset to the southeast of the interior midpoint.
An unusual, (officially) unnamed massif is present in the northwest section of the rim, which rises about 4.0 km above adjacent parts of the rim and about 7.57 km above the crater floor.
The formation of the massif does not appear to be explainable simply on the basis of the impact event that created the crater.
Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Zeeman.
