Eponym John A. Brashear

Brashear is a lunar impact crater on the far side of the Moon, in the southern hemisphere in the vicinity of the south pole. The crater is named after the American astronomer John A. Brashear. [1] It lies just to the south of the walled plain Antoniadi, within the larger crater's outer rampart of ejecta. To the northeast besides Antoniadi is the crater Numerov, and southeast lies the younger De Forest.

This formation is little more than a shallow depression in the lunar surface, its features eroded and blanketed by the ejecta from the relatively fresh crater Antoniadi just to the north.

The satellite crater Brashear P lies to the south-southwest. This formation is a heavily worn crater with features that have been almost completely worn away by subsequent impacts. Connected to the southern rim of this crater is a series of valleys and impact craters leading a couple of hundred kilometres to the east.

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 Brashear.

Cabannes (crater)

Cabannes is a lunar impact crater that lies in the southern hemisphere on the far side of the Moon. The rim has been worn by subsequent impacts, with a smaller crater overlying the southern rim. However the formation has not been significantly reshaped by nearby craters.

Murchison (crater)

Murchison is a lunar impact crater on the north edge of the Sinus Medii. It was named in honour of the geologist Sir Roderick Murchison. It shares a section of rim with the crater Pallas. To the southeast on the mare is the circular crater Chladni, and to the northeast is Ukert. Farther to the east is the prominent Triesnecker. Murchison lies astride the lunar zenith line, i.e. the starting longitude of the selenographic coordinate system.

Antoniadi (lunar crater)

Antoniadi is a large lunar impact crater that lies on the southern hemisphere on the far side of the Moon. The crater intrudes into the southeastern rim of the crater Minnaert, a slightly smaller formation that is significantly more eroded. Attached to the eastern rim of Antoniadi is Numerov, another large, ancient crater similar to Minnaert. Due south of Antoniadi is the small crater Brashear.

Pictet (crater) Lunar crater

Pictet is a lunar impact crater located just to the east of the larger and more prominent impact crater Tycho. The high-albedo rays and ejecta from Tycho lie across Pictet and spread far to the east and in other directions. Pictet is older than Tycho and is somewhat worn by past impacts. The slightly smaller crater Pictet A intrudes slightly into the southwest rim. The larger crater Pictet E is nearly joined to the north rim. To the east is Saussure, and to the northeast is the larger, worn formation Orontius.

Hohmann (crater)

Hohmann is a lunar impact crater that lies within the central basin of the Mare Orientale formation, on the farside of the Moon. It is located to the south of the crater Maunder, and to the west of Kopff crater. Due to its proximity to the western lunar limb, this area of the surface is occasionally visible during favorable librations. However the basin is viewed from the side, restricting the amount of detail that can be observed from Earth.

Crommelin (lunar crater)

Crommelin is an ancient lunar impact crater that is located in the vicinity of the south pole of the Moon, on the far side. It lies to the north of the large crater Zeeman, and to the east-northeast of Numerov.

Blackett (crater)

Blackett is a lunar impact crater that lies on the far side of the Moon, behind the southwest limb. It lies beyond the southeast outer ring of the immense Mare Orientale basin. The formation of that major feature has left Blackett deeply marked with ridge features trending from the northwest. Much of the crater has been shaped by the ejecta from Mare Orientale, particularly along the western half of the crater.

Rayleigh (lunar crater)

Rayleigh is a lunar impact crater, approximately 114 kilometers in diameter, that lies along the northeast limb of the Moon. This feature is seen edge-on from Earth, making it difficult to see much detail. In addition, libration effects can completely hide this crater from view. It lies just to the north of Lyapunov, and to the northwest of the large Joliot. Attached to its southwest rim is the smaller Urey.

Poncelet (crater)

Poncelet is the remains of a lunar impact crater that is located near the northern limb of the Moon. It lies to the east-northeast of the crater Pascal and northwest of Anaximenes. Like the latter formation, Poncelet is a worn, eroded formation with an interior that has been flooded, either with lava or possibly ejecta. The outer rim is a low, circular ridge with a narrow break to the south and a wider breach to the northeast. The interior floor is pock-marked with many tiny craterlets, the most notable of which is Poncelet H, located just to the southeast of the midpoint.

Helmholtz (lunar crater) Impact crater

Helmholtz is a lunar impact crater, approximately 110 kilometers in diameter, that is located near the south-southeast limb of the Moon. Attached to the south-southeast rim of Helmholtz is the somewhat smaller crater Neumayer. The larger crater Boussingault is nearly attached to the west-southwestern rim.

dAlembert (crater) Also named after the above

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.

Dziewulski (crater)

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.

Elvey (crater)

Elvey is a lunar impact crater that is located on the far side of the Moon. It is located near the northern edge of the blanket of ejecta that surrounds the Mare Orientale impact basin. To the north of Elvey is the smaller crater Nobel.

Fersman (crater)

Fersman is a large lunar impact crater on the Moon's far side. It lies to the east of the crater Poynting, and west-northwest of Weyl. To the south is the huge walled plain Hertzsprung.

Fowler (crater)

Fowler is a large lunar impact crater that lies in the northern hemisphere on the Moon's far side. It lies to the south-southwest of the crater Esnault-Pelterie, and north of Gadomski. Overlying the eastern rim and intruding into the interior is Von Zeipel.

Mendel (lunar crater)

Mendel is a large Impact crater that lies on the far side of the Moon. It is located in the southern fringe of the huge skirt of ejecta that surrounds the Mare Orientale impact basin. To the south-southwest of Mendel is Lippmann, an even larger crater.

Minnaert (crater)

Minnaert is a large lunar impact crater that is located on the far side of the Moon, deep in the southern hemisphere. It is partly overlain along the southeastern side by the larger and younger crater Antoniadi. To the west-northwest lies Lyman.

Numerov (crater)

Numerov is a lunar impact crater that is located on the Moon's far side, deep in the southern hemisphere. It is attached to the larger and younger crater Antoniadi to the west, and the outer rampart of Antoniadi overlies the inner wall and part of the western interior floor of Numerov. To the east-southeast is the larger walled plain Zeeman, and to the east-northeast is the old crater Crommelin.

Lippmann (crater)

Lippmann is a large lunar impact crater in the southern part of the far side of the Moon and so cannot be viewed directly from the Earth. Just to the northeast is the walled plain Mendel, only slightly smaller than Lippmann. To the south-southeast lies the crater Petzval.

Tsander (crater)

Tsander is a large lunar impact crater on the far side of the Moon. Attached to the southeastern outer rim is the younger crater Kibal'chich. To the northwest lies Dirichlet, and to the northeast lies Artem'ev.
