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.

Borel (crater) Lunar impact crater

Borel is a tiny lunar impact crater located in the southeast part of Mare Serenitatis. It was named after French mathematician Émile Borel. To the northeast is the crater Le Monnier and to the southeast is the crater Abetti. Borel was previously identified as Le Monnier C.

Atlas (crater) Lunar impact crater

Atlas is a prominent lunar impact crater that is located in the northeast part of the Moon, to the southeast of Mare Frigoris. Just to the west is the slightly smaller but still prominent crater Hercules. Northeast of Atlas is the large Endymion.

Barocius (crater) Lunar impact crater

Barocius is an ancient lunar impact crater that is located in the rugged southern highlands of the Moon. It was named after Italian mathematician Francesco Barozzi. It lies just to the southeast of the large crater Maurolycus. To the southwest of Barocius is Clairaut, and to the south-southeast lies Breislak.

Anuchin (crater)

Anuchin is a lunar impact crater that lies on the southern hemisphere on the far side of the Moon. It is located to the south of the larger crater Lamb, and to the north-northwest of Kugler.

Fizeau (crater) Lunar impact crater

Fizeau is a prominent lunar impact crater that is located on the far side of the Moon, in the southern hemisphere. Nearby craters of note include Minkowski to the west-northwest, and Eijkman to the southwest.

Chamberlin (lunar crater) Lunar impact crater

Chamberlin is a lunar impact crater that is located on the far side of the Moon, just past the southeastern limb. It lies to the southeast of the crater Jeans, and Moulton is attached to the southeastern rim of Chamberlin. This crater is located in a part of the lunar surface that has undergone resurfacing of crater interiors, producing dark-hued crater floors.

Becquerel (lunar crater) Lunar impact crater

Becquerel is a lunar impact crater that lies in the northern hemisphere on the far side of the Moon. This is an ancient and heavily worn formation that is now little more than an irregular buri in the surface. The outer rim has been worn and reshaped until it forms a rugged, mountainous region around the flatter interior.

Clausius (crater) Lunar impact crater

Clausius is a lunar impact crater that is located in the southwest part of the Moon, in the small lunar mare designated Lacus Excellentiae. It is completely enclosed by mare material, although the tiny satellite crater Clausius A lies just to the north. The rim of Clausius is low and sharp, with a slightly oval shape that is longer in the north–south direction. The interior floor has been flooded by basaltic lava, and appears level and featureless with a darker surface that matches the mare surface that surrounds the crater exterior.

Berosus (crater) Lunar impact crater

Berosus is a lunar impact crater that is located in the northeast part of the Moon, less than one crater diameter northwest of Hahn. Further to the east-northeast is the large crater Gauss, and to the north-northwest lies Bernoulli. Because of its location, this crater appears foreshortened when viewed from the Earth.

Darney (crater) Lunar crater

Darney is a small lunar impact crater that is located on the region of the Moon where the Mare Nubium joins the Oceanus Procellarum. It was named after French astronomer Maurice Darney. To the south is the lava-flooded crater Lubiniezky. The southern rim of Darney is attached to a series of low ridges that extend to the southwest.

Bredikhin (crater)

Bredikhin is a lunar impact crater that is located on the far side of the Moon. It lies just to the west of the crater Mitra, and northeast of Raimond.

Gauss (crater)

Gauss is a large lunar impact crater, named after Carl Friedrich Gauss, that is located near the northeastern limb of the Moon's near side. It belongs to a category of lunar formations called a walled plain, meaning that it has a diameter of at least 110 kilometers, with a somewhat sunken floor and little or no central massif. Due to its location, this crater appears considerably foreshortened when viewed from the Earth, and its visibility is affected by libration.

Casatus (crater) Lunar impact crater

Casatus is a lunar impact crater that is located near the southern limb of the Moon. The north-northeast rim of the crater overlies a portion of the slightly larger crater Klaproth. Along the western rim, Casatus A intrudes somewhat into the interior, producing an inward-bowing rim. To the southeast of Casatus is Newton.

Damoiseau (crater) Lunar impact crater

Damoiseau is a lunar impact crater that is located just to the west of the Oceanus Procellarum, in the western part of the Moon's near side. It lies due east of the prominent crater Grimaldi, a walled plain with a distinctive dark floor. Due south of Damoiseau is the crater Sirsalis.

Demonax (crater) Lunar impact crater

Demonax is a lunar impact crater near the southern limb of the Moon. This location makes the crater difficult to observe due to foreshortening. The crater is also illuminated at a very low angle, when it is in the sunlit side. Demonax lies just to the north of the crater Scott, one of the south polar formations. To the north-northwest is Boguslawsky.

Cassegrain (crater) Lunar impact crater

Cassegrain is a lunar impact crater that is located on the far side of the Moon, beyond the southeastern limb. It lies to the southeast of the larger crater Lebedev, and to the northeast of the comparably-sized Priestley.

Chrétien (crater) Lunar impact crater

Chrétien is a lunar impact crater that is located in the southern hemisphere on the far side of the Moon from the Earth. It lies due south of the Mare Ingenii, one of the few maria on the Moon's far side. The crater lies in the midpoint between the craters Garavito to the west-southwest and Oresme to the east-northeast, both of these being somewhat smaller than Chrétien.

Faye (crater) Lunar impact crater

Faye is a heavily eroded lunar impact crater in the rugged southern highlands of the Moon. It is named after French astronomer Hervé Faye. It is attached to the northeastern rim of the crater Delaunay, with Donati located just a few kilometers to the northeast. It forms part of a chain of craters of increasing size to the southwest that continues with La Caille and ends with the walled plain Purbach.

Edison (crater)

Edison is a lunar impact crater on the far side of the Moon. It is located just behind the north-northeastern limb of the Moon, a region that is sometimes brought into sight from Earth during favorable librations. However even at such times not much detail can be discerned, and the crater is better observed by orbiting spacecraft.

Foster is a small lunar impact crater that lies to the southeast of the larger crater Joule, on the far side of the Moon. The rim of Foster is slightly eroded, and the narrow inner walls slope directly down to the relatively dark interior floor. The rim has a small outward bulge along the southwest side. There is a small craterlet on the floor next to the northern rim. A tiny impact in the southeast part of the crater interior is surrounded by a small skirt of high albedo material, producing a bright patch.
