Eponym | William H. Bragg |
Bragg is an ancient lunar impact crater that is located on the far side of the Moon, just beyond the northwest limb. This formation has been heavily eroded and reshaped by subsequent impacts, leaving an irregular depression in the surface. The most intact portion of the rim is along the western face, while the northern and eastern rim has been nearly worn away and is overlaid by several smaller craters. The most notable of these is Bragg H, which lies across the east-southeastern rim.
This crater is located to the north-northwest of the walled plain Lorentz. Nearby craters of note include Rynin to the north, Stefan to the northwest, Lacchini to the west, and Avicenna to the southeast. The region about this crater is very rugged and marked by many smaller impacts.
Prior to formal naming by the IAU in 1970, [1] Bragg was called Crater 102. [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 Bragg.

Alter is a lunar impact crater that is located in the northern hemisphere on the far side of the Moon. It lies to the southwest of the larger crater Robertson, and to the east of Ohm.
Ansgarius is a lunar impact crater that is located near the eastern limb of the Moon. When viewed from the Earth, the crater has a highly oval shape due to foreshortening, but the rim is actually nearly circular. To the northwest of Ansgarius is the crater La Pérouse, and south is Behaim.
Arrhenius is a lunar impact crater that is located just on the far side of the Moon, near the southwest limb. In this location the vicinity of the crater can be viewed during favorable librations, although it is viewed from on edge. To the south-southeast is the worn crater Blanchard, and De Roy lies further to the west.
Artamonov is a lunar impact crater on the far side of the Moon. Its eroded outer rim does not have the circular shape of most lunar craters, but the overall shape of three or four merged craters. The largest is in the south, with smaller circular bulges to the north and east.
Atwood is a small earth moon impact crater that is located on the Mare Fecunditatis, to the northwest of the prominent crater Langrenus. It forms a triple-crater formation with Naonobu attached to the north rim and Bilharz near the west rim.
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 polymath 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. It was named by the IAU in 1964 for astronomer Lewis Boss.
Back is a small lunar impact crater that is located near the eastern limb of the Moon. It lies on the northwest edge of the Mare Smythii, and the northeast rim is adjacent to the crater Schubert. To the west is Jenkins, and to the southwest is the Weierstrass–Van Vleck crater pair.
Fechner is a lunar impact crater that lies on the far side of the Moon's southern hemisphere, attached to the western rim of the large walled plain Planck. The eastern rim of Fechner intersects the Vallis Planck, a long, wide cleft in the surface that follows a course to the north-northwest. This valley intrudes into the southeastern rim of the crater, then continues northwards from the periphery of the northeast rim.
Berkner is a lunar impact crater that is located on the far side of the Moon, just past the western limb. It is attached to the east-southeast rim of the crater Parenago. Just to the south is the Robertson, and to the southeast is Helberg.
Bunsen is a lunar impact crater that lies near the northwestern limb of the Moon. It is located to the west of the Oceanus Procellarum and the crater von Braun. To the southeast is the crater Lavoisier, and to the northeast lies Gerard. Northwest of Bunsen, on the far side of the Moon, is McLaughlin. Due to its position this crater appears foreshortened when viewed from the Earth, and its visibility is affected by libration.
Blanchard is a lunar impact crater that lies on the far side of the Moon, just behind the southwestern limb. It lies to the south-southwest of the crater Arrhenius, and northwest of Pilâtre. Further to the south is the rugged terrain to the north of the walled plain Hausen.
Chapman is a lunar impact crater that lies just beyond the northwest rim of the Moon, on the far side as seen from the Earth. It lies to the northeast of the crater Rynin, and southward of the large walled plain Poczobutt.
Carrington is a lunar impact crater that is located just to the northeast of the crater Schumacher, in the northeastern part of the near side of the Moon. Carrington was named by the IAU in 1935. It lies in a stretch of rough terrain between two small lunar maria, with Lacus Temporis to the northwest and the smaller Lacus Spei to the east. To the northeast of Carrington is Mercurius.
Chauvenet is a lunar impact crater that is located to the northeast of the prominent crater Tsiolkovskiy on the far side of the Moon. Less than one crater diameter to the northwest of Chauvenet is the crater Ten Bruggencate.
FitzGerald is a large lunar impact crater on the far side of the Moon. It lies to the west-southwest of the crater Cockcroft, and about two crater diameters to the northeast of Morse.
Fleming is a large lunar impact crater that is located on the Moon's far side, and cannot be seen from the Earth. It lies about a crater diameter to the east-northeast of Hertz, and to the northwest of Lobachevskiy.
Garavito is a lunar impact crater that is located in the southern hemisphere on the Moon's far side. It lies to the north-northwest of the huge walled plain Poincaré, and to the west of the crater Chrétien. It takes its name in honor of the Colombian astronomer and engineer Julio Garavito Armero.
Möbius is a lunar impact crater that is located on the Moon's far side, beyond the eastern limb and northeast of the Mare Marginis. It lies less than one crater diameter to the northwest of the larger, 90-km-diameter Hertz, and just to the southeast of Popov. To the north of Mobius is the crater chain designated Catena Dziewulski, which takes its name from the crater Dziewulski to the north-northwest.
Šafařík is a small lunar impact crater on the far side of the Moon. It lies due north of the crater Tiselius and to the east-southeast of Sharonov. This is a worn and eroded crater with smaller impacts along the rim to the east and northwest. The remainder of the worn rim and the interior are relatively featureless.
