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.[1] The formation of the massif does not appear to be explainable simply on the basis of the impact that created the crater.[2]
