Hayn is a lunar impact crater that lies next to the northeast limb of the Moon. This location restricts the amount of detail that can be viewed from the Earth, as the western inner side is permanently hidden from sight. Observation of this crater can also be affected by libration, which can completely hide this crater from sight.
This crater lies across the northwestern rim of the walled plain Bel'kovich, to the north of the Mare Humboldtianum. It is otherwise relatively isolated from other named craters, with the nearest being Cusanus to the northwest.
This is a young crater with a rim and interior that have not yet been significantly eroded. It has a circular but somewhat uneven rim and an inner wall containing a number of terraces. The southern rim is slightly more pronounced in height where it joins the heavily worn rim of Bel'kovich. There is also an outer rampart beyond the rim that is more extensive to the southwest. Of the rim of Bel'kovich to the east of Hayn there is little sign, and the ground to the east is not dissimilar to the other terrain surrounding the crater. The crater has a ray system, and is consequently mapped as part of the Copernican System. [1]
The interior floor is relatively flat compared to the terrain surrounding the crater. A system of several ridges lie near the interior midpoint, with a wide valley running north–south that divides the range in half. There are also smaller lateral valleys, and all told there are some half dozen peaks. The remainder of the floor also contains several smaller hills, particularly just to the west of the central peaks.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Hayn.

Anaxagoras is a young lunar impact crater that is located near the north pole of the Moon. It lies across the larger and more heavily worn crater Goldschmidt. To the south-southeast is Epigenes, and due south is the worn remains of Birmingham.
Faraday is a lunar impact crater in the southern highlands of the Moon. It was named after British chemist and physicist Michael Faraday. It lies across the southeast rim of the larger crater Stöfler, and the northwest rim of Faraday forms a wide rampart across the otherwise flat floor of Stöfler. To the east of Faraday is Maurolycus.
Aristillus is a prominent lunar impact crater that lies in the eastern Mare Imbrium. It was named after Greek astronomer Aristyllus. Directly to the south is the smaller crater Autolycus, while to the southwest is the large Archimedes. To the northeast are the craters Theaetetus and Cassini.
Eudoxus is a prominent lunar impact crater that lies to the east of the northern tip of the Montes Caucasus range. It is named after the Greek astronomer Eudoxus of Cnidus. It is located to the south of the prominent crater Aristoteles in the northern regions of the visible Moon. To the south is the ruined formation of Alexander, and the small crater Lamèch lies to the southwest.
Kepler is a lunar impact crater that lies between the Oceanus Procellarum to the west and Mare Insularum in the east. To the southeast is the crater Encke. Kepler is named for the 17th century German astronomer and mathematician Johannes Kepler.
Bürg is a prominent lunar impact crater in the northeast part of the Moon. It lies within the lava-flooded, ruined crater formation designated Lacus Mortis. To the south and southeast is the crater pair Plana and Mason. To the west, beyond the rim of Lacus Mortis, is the prominent crater Eudoxus.
Boyle is a lunar impact crater that is located in the southern hemisphere on the rugged far side of the Moon. It is adjacent to the larger crater Hess to the southeast, and lies about midway between the craters Alder to the north-northeast and Abbe to the south-southwest.
Bel'kovich is a large lunar impact crater of the form termed a walled plain. The formation has been heavily eroded by a history of subsequent impacts, leaving it reshaped, worn, and the features softened and rounded. Bel'kovich is located along the northeastern limb of the Moon, and so its visibility is subject to libration effects. From the Earth this crater is viewed from the side, making it difficult to view it in detail.
Fabry is a large lunar impact crater of the form termed a walled plain. It is located on the far side of the Moon, just beyond the northeastern limb. Parts of this area are sometimes brought into view by the effects of libration, but the terrain is seen from the edge and so not much in the way of detail can be observed.
Bell is a lunar impact crater that is located on the far side of the Moon, just past the western limb. It lies in an area of terrain that is marked by many small craters, a number of which are satellite craters of Bell listed in the table below. Bell lies within two crater diameters of Laue to the north, and to the west of the smaller Helberg.
Carpenter is a lunar impact crater in the northern part of the Moon, relatively close to the limb. At this position the crater is foreshortened and appears oval in shape. It is, however, very nearly circular in outline. The outer rampart to the south is adjoined to the old crater Anaximander, and the satellite formation Anaximander B lies along the western rim. To the northeast is Anaximenes.
Brouwer is a large lunar impact crater that is located in the southern hemisphere on the far side of the Moon. Intruding into the western rim of Brouwer is the younger and somewhat smaller crater Langmuir. Further to the east-southeast is the larger walled plain Blackett.
Buffon is a lunar impact crater that is located on the southern hemisphere on the far side of the Moon. It lies a crater diameter south of the large walled plain Chebyshev. To the northeast is the crater Langmuir and to the southwest is Leavitt. Buffon lies nearly at the midpoint between these formations.
Pasteur is a large lunar impact crater, approximately 233 kilometers in diameter, belonging to the category termed a walled plain. It was named after French chemist and microbiologist Louis Pasteur. It lies on the far side of the Moon as seen from the Earth, just beyond the eastern limb. The vicinity of this crater is occasionally brought into view from Earth due to librations, although not much detail can be seen.
Crookes is a lunar impact crater that lies on the Moon's far side as seen from the Earth. It lies just to the southwest of the giant crater Korolev. To the southwest of Crookes is McKellar.
Chaplygin is a large lunar impact crater that lies on the far side of the Moon. It is located to the southeast of the huge walled plain Mendeleev, about midway between the craters Schliemann to the northeast and Marconi to the southwest. It is about the same size as Albategnius on the near side.
Ibn Firnas is a lunar impact crater on the far side of the Moon. In 1976 it was named after Abbas Ibn Firnas, a polymath from Andalucia who, in the 9th century, devised a chain of rings that could be used to simulate the motions of the planets and stars.
Dziewulski is a lunar impact crater on the far side of the Moon. It lies between the craters Edison to the north and Popov to the south. The outer rim of this crater has been considerably worn by impacts, particularly along the southwest quadrant where the satellite crater Dziewulski Q overlies the rim and the interior floor. The northern rim is also heavily disrupted, and several small crater lie along the southeast rim. The interior floor and surrounding terrain has been resurfaced.
Das is a lunar impact crater on the far side of the Moon. It is located to the northwest of the walled plain Chebyshev. To the southwest of Das is the irregular crater Mariotte, and Von der Pahlen lies to the east-northeast. The crater was named after Indian astronomer Amil Kumar Das.
Larmor is a crater on the Moon's far side. It is located to the east-southeast of Shayn and due north of Dante. It is named in honor of the physicist Joseph Larmor.
