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]

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]

Hommel is a lunar impact crater located in the southeast section of the Moon, in a region that is deeply impacted with a multitude of impact craters. The most notable craters nearby are Pitiscus to the north; Rosenberger due east; and Nearch to the southeast. The prominent crater Vlacq is nearly attached to the northeast rim. Also nearby is Asclepi to the west. Hommel is about 120 kilometers in diameter and its walls reach heights of 2,800 meters. It is from the Pre-Nectarian period, 4.55 to 3.92 billion years ago.

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.

<span class="mw-page-title-main">Calippus (crater)</span> Crater on the Moon

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.

<span class="mw-page-title-main">Belʹkovich (crater)</span> Lunar impact crater

Belʹkovich 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. Belʹkovich 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.

<span class="mw-page-title-main">Borda (crater)</span> Lunar impact 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 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.
