Eponym | Lorentz Eichstadt |
Eichstadt is a lunar impact crater that is located in the eastern section of the Montes Cordillera range that encircles the Mare Orientale impact basin. It lies toward the southwestern limb of the Moon, and so appears oblong when viewed from the Earth due to foreshortening. Over 200 kilometers to the east of Eichstadt are the craters Darwin and Lamarck, and to the south is Krasnov.
The rim of this crater is well-defined and forms a somewhat uneven circle. There are slight outward bulges in the perimeter to the south-southeast, southwest, and to the north. There are some terraces along the inner wall and the top edge is slumped. In the central part of the interior floor is a cluster of low, rugged ridges.
The crater is named after German mathematician and astronomer Lorentz Eichstadt.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Eichstadt.

Bettinus is a lunar impact crater located near the southwest limb. Due to its location, the crater has a distinctly oval shape because of foreshortening. To the south of the rim is the similar-sized crater Kircher, and to the northwest is the slightly smaller Zucchius. From the west to the southwest, closer to the limb, is the giant formation Bailly.
Brewster is a small lunar impact crater in the northern fringes of Sinus Amoris. It was named after the Scottish scientist, Sir David Brewster. Its diameter is 9.8 km. It lies to the southwest of the larger crater Römer. To the southeast of Brewster is the similar-sized Franck. This crater is cup-shaped and symmetrical, with no overlapping craters of note. A low ridge is attached to the northern rim. The crater interior has a relatively high interior albedo compared to the surrounding terrain.
Cajal is a small lunar impact crater on the northern part of the Mare Tranquilitatis. It was named after the Spanish doctor and Nobel laureate Santiago Ramón y Cajal. It is a circular, cup-shaped formation that lies southeast of the lava-inundated crater Jansen. Cajal was formerly designated Jansen F. Also to the northwest is a system of wrinkle ridges designated the Dorsa Barlow.
C. Herschel is a small lunar impact crater that lies on the western part of Mare Imbrium. It is named after British astronomer Caroline Herschel. It is a circular, bowl-shaped formation that has not undergone significant erosion. The interior floor has the same low albedo as the surrounding lunar mare. To the south-southwest is the similar crater Heis. C. Herschel lies on a wrinkle ridge of the lunar mare named the Dorsum Heim.
Crile is a tiny lunar impact crater. It is roughly circular and cup-shaped, with interior walls that slope down to the midpoint. The crater lies in the Palus Somni, between the Mare Crisium to the east and Mare Tranquillitatis to the west.
Fernelius is a lunar impact crater located in the southern highlands just to the north of the walled plain Stöfler. It was named after 16th century French astronomer Jean Fernel. The crater Kaiser is located next to the northwest rim of Fernelius. To the north-northwest are the craters Nonius and Walther. Southeast of Fernelius is the crater cluster of Miller, Nasireddin, Huggins, and Orontius.
Abenezra is a lunar impact crater located in the rugged highlands in the south-central section of the Moon. Abenezra is named after the Sephardic Jewish sage, poet, biblical commentator, astronomer, and astrologer Abraham ibn Ezra, It is attached along the southeast rim to the crater Azophi. To the northeast lies the crater Geber, and further to the southeast is the larger Sacrobosco.
Avicenna is a lunar impact crater that lies on the far side of the Moon, just beyond the western limb on the northern rim of the Lorentz basin. It is named after the Persian physician Avicenna. It lies to the north-northwest of the larger crater Nernst, and to the southeast of Bragg.
Boss is a lunar impact crater that is located along the northeast rim of the Moon's near side. Due to its location, the crater is viewed from the side by observers on the Earth, and its visibility is subject to libration effects.
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.
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.
Carver is a lunar impact crater that is located on the far side of the Moon, due east of the walled plain Van der Waals. To the northeast is the crater Rosseland, and to the south-southeast lies Kozyrev.
Cooper is a lunar impact crater that is located in the northern hemisphere on the far side of the Moon. It lies to the east of the large walled plain D'Alembert, and west-southwest of the crater Chappell.
Chernyshev is a lunar impact crater that is located in the northern part of the Moon's far side. It lies to the northeast of the crater Chandler, and to the southeast of the walled plain D'Alembert.
Krasnov is a lunar impact crater that is located in the southeastern part of the Montes Cordillera range, near the southwest limb of the Moon. From the Earth this crater appears foreshortened, and visibility can be affected by libration. To the north of Krasnov is the crater Eichstadt and to the southwest is Shaler, both along the edge of the Montes Cordillera mountain ring.
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.
Douglass is a lunar impact crater on the far side of the Moon. It lies to the southwest of the crater Frost and south-southwest of the large walled plain Landau.
Delporte is a lunar impact crater on the far side of the Moon. It overlies part of the northwestern rim of the huge walled plain Fermi, and the crater Litke is nearly attached to the southeastern rim. The crater is named after Eugène Joseph Delporte.
Dunér is an old lunar impact crater that is located in the northern hemisphere on the far side of the Moon. It lies to the southeast of the crater Chernyshev, and west-southwest of the Perkin–Debye crater pair.
Eijkman is a lunar impact crater that is located on the far side of the Moon's southern hemisphere. It lies about a half crater diameter to the southeast of the larger crater Lemaître. To the south-southwest is the crater Crommelin, and to the northeast is Fizeau.
