Becquerel is a lunar impact crater that lies in the northern hemisphere on the far side of the Moon. This is an ancient and heavily worn formation that is now little more than an irregular buri in the surface. The outer rim has been worn and reshaped until it forms a rugged, mountainous region around the flatter interior.
The most notable of the formations on the rim is Becquerel X, which is part of a double crater along the northwestern rim. There is a short valley paralleling the southwestern rim, most likely formed by the merging of several small craters. The interior floor of Becquerel is relatively flat, but with rough sections and several tiny craterlets marking the surface. There is a dark patch (low albedo) on the floor near the southern rim.
To the west of Becquerel are H. G. Wells and Tesla, to the north is Segers, to the northeast is Bridgman, and to the south is Van Maanen.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Becquerel.

Anaximenes is a low-rimmed lunar impact crater near the north-northwest limb of the Moon. It lies to the west of the crater Philolaus, and northeast of Carpenter. To the northwest is Poncelet, close to the visible edge of the Moon.
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.
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.
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.
Bridgman is a lunar impact crater that is located on the far side of the Moon. It lies in the northern hemisphere, to the northwest of the crater Kurchatov. To the west-southwest is the old formation Becquerel, and eastward are the craters Pawsey and Wiener.
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.
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.
Cannon is a lunar impact crater that is located near the east-northeastern limb of the Moon's near side. It lies just to the northwest of the Mare Marginis, and south-southeast of the crater Plutarch. Farther to the east-northeast is Hubble.
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.
Perrine is a lunar impact crater that is located on the northern hemisphere on the far side of the Moon. It lies to the west of the large walled plain Landau, and to the northeast of the crater Charlier. To the north-northwest is the smaller Gullstrand.
Davisson is a lunar impact crater that is located on the far side of the Moon from the Earth. This crater lies across the eastern rim of the huge walled plain Leibnitz, and the rim and outer rampart intrudes into the interior floor of Leibnitz. To the east-northeast of Davisson is the walled plain Oppenheimer, a formation only somewhat smaller than Leibnitz.
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.
Chevallier is a lunar impact crater that is located in the northeastern part of the Moon's near side, about a crater diameter east-southeast of the prominent crater Atlas. To the south-southeast of Chevallier is the flooded crater Shuckburgh. Chevallier was named by the IAU in 1935.
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.
Dyson is a lunar impact crater, 63 kilometers in diameter, that lies on the far side of the Moon, past the northwest limb. It is located in the northern part of the surface, to the northwest of the crater Coulomb, and east of van't Hoff.
Kimura is a small impact crater that is located on the Moon's far side, beyond the southeastern limb. It lies to the west-northwest of the crater Fechner, along the northeastern rim of an unnamed basin in the surface.
Drebbel is a small lunar impact crater named after Cornelius Drebbel that is located to the northeast of the large walled plain Schickard, in the southwestern part of the Moon. Further to the northeast is the Lacus Excellentiae and the small crater Clausius.
Chandler is a lunar impact crater in the northern hemisphere, on the Moon's far side. It lies to the southeast of the large walled plain D'Alembert, and southeast of the slightly smaller Chernyshev crater.
Nobili is a lunar impact crater that lies near the eastern limb of the Moon, giving it a foreshortened appearance when viewed from the Earth. The crater overlies the western rim of the slightly larger crater Schubert X, and the eastern rim of this satellite crater is overlain in turn by Jenkins, resulting in a triple crater formation. To the south lies Gilbert.
Kurchatov is a lunar impact crater that is located on the Moon's far side. It is just to the southwest of the crater Wiener, and farther to the southeast of Bridgman. A couple of crater diameters to the south of Kurchatov is the northern edge of the Mare Moscoviense.
