Hahn is a lunar impact crater that is located near the northeastern limb of the Moon. The crater appears oval when viewed from the Earth due to foreshortening. It is located less than one crater diameter to the southeast of Berosus, a slightly smaller formation.

The inner wall of Hahn contains a system of terraces, particularly in the southern half. A smaller crater lies across the northwest rim, forming a break that reaches the interior floor. The interior floor has a region of lower albedo in the northern half, making it darker in appearance than the southern section of the floor. At the midpoint of the interior is an elongated central ridge, with the longer extent oriented north–south. The floor is also marked by several tiny craterlets.

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 Hahn.

gollark: Well, that's two different viewpoints there.

gollark: I seem to be able to get individual drive info with my whatever-this-HP ML110 G7-has and `smartctl`.

gollark: I think.

gollark: If it's only slightly behind, which it might be, you can upgrade the CPUs.

gollark: You can probably swap the processors for 6-core xeons cheaply, at least.
