Eponym Daniel Santbech (Noviomagus)

Santbech is a lunar impact crater that is located to the southeast of Mare Nectaris. It lies south-southwest of the prominent crater Colombo. About one crater diameter to the east-northeast is the smaller Monge. The terrain around the crater, although rugged in places, has been flooded by lava and so has a low albedo and a relatively flat surface. It was named after the 16th-century Dutch mathematician and astronomer Daniel Santbech Noviomagus. [1] It is from the Pre-Imbrian period, 4.55 to 3.85 billion years ago. [2]

Lunar craters craters on Earths moon

Lunar craters are impact craters on Earth's Moon. The Moon's surface has many craters, almost all of which were formed by impacts.

Impact crater Circular depression on a solid astronomical body formed by a hypervelocity impact of a smaller object

An impact crater is an approximately circular depression in the surface of a planet, moon, or other solid body in the Solar System or elsewhere, formed by the hypervelocity impact of a smaller body. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Impact craters range from small, simple, bowl-shaped depressions to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth.

Mare Nectaris lunar mare

Mare Nectaris is a small lunar mare or sea located south of Mare Tranquillitatis southwest of Mare Fecunditatis, on the near side of the moon. Montes Pyrenaeus borders the mare to the east and Sinus Asperitatis fuses to its northwestern edge. It is 84,000 square kilometers in size.

The outer rim of this crater stands above the surrounding terrain, with an irregular outer rampart. The rim perimeter is somewhat irregular, and has been disturbed in several locations by subsequent impacts. There are small craters along the eastern and northwestern rim, and an asymmetrical formation along the southern inner wall. The northern rim is uneven, with a diagonal gouge running to the southeast. Much of the interior floor is level and nearly featureless, with a small central peak offset to the north-northeast of the midpoint. [2]

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Santbech. [3]

Cleomedes (crater) impact crater

Cleomedes is a prominent lunar impact crater located in the northeast part of the visible Moon, to the north of Mare Crisium. It was named after Greek astronomer Cleomedes. It is surrounded by rough ground with multiple crater impacts. The irregular crater Tralles intrudes into the northwest rim. To the east is Delmotte. North of Cleomedes is a triple-crater formation with Burckhardt occupying the center.

Donati (crater) impact crater

Donati is a lunar impact crater that is located in the rugged south-central highlands of the Moon. It lies just to the northwest of the crater Faye, and the two outer rims are separated by a gap of less than 10 kilometers. To the north is the comparably sized Airy, and farther to the southeast is Playfair. Donati is 36 kilometers in diameter.

Boyle (crater) lunar crater

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.

Calippus (crater) impact crater

Calippus is a small lunar impact crater that is located on the eastern edge of the rugged Montes Caucasus mountain range in the northern part of the Moon. It was named after Greek astronomer Callippus of Cyzicus. It lies to the southwest of the crater remnant Alexander, to the northwest of the Mare Serenitatis.

Belkovich (crater) lunar crater

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.

Borda (crater) lunar crater

Borda is a lunar impact crater that lies between Santbech to the north-northwest and Reichenbach slightly further away to the south-southeast. It was named after French astronomer Jean-Charles de Borda. It has a low rim that is broken along the southeast by a smaller crater. The rim is intruded into by another small crater along the southwest side, and there is an irregular cleft along the northwest face. There is a central peak at the midpoint of the floor.

Fabry (crater) impact crater

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.

Curtius (crater) impact crater

Curtius is a lunar impact crater that is located in the southern part of the Moon. From the Earth the crater appears foreshortened, making it more difficult to observe detail. Nevertheless, this is a large crater that can be readily found in even small telescopes. Curtius is located within one crater diameter of the still-larger Moretus to the southwest. To the northeast is the smaller Pentland. Curtius is 95 kilometers in diameter and 6.8 kilometers deep. It is from the Nectarian period, 3.92 to 3.85 billion years ago.

Hall (lunar crater) lunar crater

Hall is a lunar impact crater in the southeast part of the Lacus Somniorum, a lunar mare in the northeast part of the Moon. It was named after American astronomer Asaph Hall. This feature can be found to the east of the prominent walled plain Posidonius. Just to the south, and nearly attached to the southern rim of Hall is the smaller crater G. Bond.

Darwin (lunar crater) Lunar impact crater

Darwin is a lunar impact crater of the type categorised as a walled plain. It lies in the southeastern part of the Moon, and is sufficiently close to the limb to appear significantly foreshortened when viewed from the Earth. Attached to its southern rim is Lamarck. To the northeast is the dark-floored crater Crüger.

Chebyshev (crater) lunar crater

Chebyshev is a large lunar impact crater that lies in the southern hemisphere on the far side of the Moon. The somewhat smaller crater Langmuir is intruding into the east-southeastern rim of Chebyshev, forming a chain of large craters with Brouwer on Langmuir's eastern rim.

dAlembert (crater)

d'Alembert is a large lunar impact crater located in the northern hemisphere on the far side of the Moon, to the northeast of the somewhat smaller walled plain Campbell. Astride the southwest rim of d'Alembert is Slipher. To the north is the crater Yamamoto, and to the south-southwest lies Langevin. This walled plain has the same diameter as Clavius on the near side, making it one of the largest such formations on the Moon.

Schwarzschild (crater) lunar crater

Schwarzschild is a large lunar impact crater, approximately 211 kilometers (131 mi) in diameter. It is located in the northern part of the Moon's far side. The nearest craters of note are Seares to the northeast, and Gamow to the southeast. It was named after German physicist and astronomer Karl Schwarzschild (1873–1916).

Debye (crater)
