Avogadro is an ancient lunar impact crater that is located in the northern hemisphere on the far side of the Moon. The formation has been heavily worn and eroded by subsequent impacts, so that the rim is now little more than a rounded edge surrounding the crater depression. The crater floor is equally worn, being covered in a multitude of smaller craters of various sizes. Many of these smaller craters have also been eroded, leaving little more than a faint trace on the surface.

Nearby craters of note include Tikhov, which is nearly attached to the southeast rim, Oberth to the west, and Schjellerup to the north-northwest. To the south-southwest is the crater Yamamoto, and farther to the south is the large walled plain D'Alembert.

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 Avogadro.

Anaximenes (crater)

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.

Doppelmayer (crater)

Doppelmayer is the remains of a lunar impact crater that lies on the southwest edge of Mare Humorum. It was named after the German mathematician and astronomer Johann Gabriel Doppelmayr. To the south-southeast is another flooded crater designated Lee, and to the southeast is Vitello. Just to the east-northeast of Doppelmayer lies the nearly submerged crater Puiseux.

Arrhenius (lunar crater)

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.

Avicenna (crater)

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 physician Avicenna. It lies to the north-northwest of the larger crater Nernst, and to the southeast of Bragg.

Buch (crater)

Buch is an old, worn crater that is located in the rugged southern highlands of the Moon. It was named after German geologist Leopold von Buch. It lies to the northeast of the large crater Maurolycus, and the comparably sized crater Büsching is attached to the northeast rim.

Bohr (crater)

Bohr is a lunar impact crater that is located near the western lunar limb, in the area that is affected by librations. It is attached to the southwestern rim of the larger, eroded Vasco da Gama formation, and to the southeast of the crater Einstein. The crater was observed for the first time in 1963, by Arthus and Ewen Whitaker in the book Rectified Lunar Atlas.

Büsching (crater)

Büsching is a lunar impact crater that is located in the crater-covered southern highlands of the Moon. It was named after German geographer Anton F. Büsching. The similar-sized crater Buch is located adjacent to its southwestern rim, and further to the southwest lies Maurolycus.

Birkhoff (crater)

Birkhoff is a giant lunar walled plain that is located on the far side of the Moon, in the northern hemisphere. This formation is an ancient impact site that has been heavily eroded, and the surface reshaped by multiple craters in the interior and along the rim. The outer wall is bordered by the craters Carnot to the south, Rowland along the west rim, and Stebbins to the north. Just to the northeast is van't Hoff.

Bell (crater)

Bell is a lunar impact crater that is located on the far side of the Moon, just past the western limb. It lies in an area of terrain that is marked by many small craters, a number of which are satellite craters of Bell listed in the table below. Bell lies within two crater diameters of Laue to the north, and to the west of the smaller Helberg.

Berlage (crater)

Berlage is an old lunar impact crater that lies in the southern hemisphere on the far side of the Moon. The smaller crater Bellinsgauzen is attached to its northern rim, and Cabannes is less than one crater diameter to the northwest. To the east-northeast of Berlage is Lemaître.

Berkner (crater)

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.

Belopolskiy (crater)

Belopol'skiy is a lunar impact crater that is located on the far side of the Moon. It lies to the west of the crater Houzeau, and northeast of Strömgren. Just to the northwest of Belopol'skiy is the crater Ioffe.

Bronk (crater)

Bronk is an eroded crater that lies on the far side of the Moon, out of sight from the Earth. It lies to the southeast of the larger crater Kovalevskaya. Less than one crater diameter to the east-northeast is the smaller crater Bobone.

Cannizzaro (crater)

Cannizzaro is a lunar impact crater that is located on the Moon's far side as seen from the Earth, just beyond the northwestern limb. It lies in a region of the surface that is sometimes brought into view due to the effects of libration, but not much detail can be seen since this feature is viewed from the side. The crater lies across the southwestern rim of the much larger-walled plain Poczobutt.

Dove is a small lunar impact crater that is located in the rugged lunar highlands in the southeastern part of the Moon. It lies to the north of the prominent crater Pitiscus.

Chernyshev (crater)

Chernyshev is a lunar impact crater that is located in the northern part of the Moon's far side. It lies to the northeast of the crater Chandler, and to the southeast of the walled plain D'Alembert.

Comrie (crater)

Comrie is a lunar impact crater. It is located on the rugged far side of the Moon relative to the Earth, beyond the western limb. Nearby craters of note include Ohm to the south-southwest, Shternberg to the southwest, and Parenago to the northeast.

Cockcroft (crater)

Cockcroft is a lunar impact crater that is situated on the far side of the Moon from the Earth, so that it has only be observed and photographed from orbit. It lies to the northeast of the larger crater Fitzgerald, and southeast of Evershed.

Evdokimov (crater)

Evdokimov is a lunar impact crater on the far side of the Moon. It lies to the east of the crater Evershed, and west-southwest of Gadomski. This is a worn and eroded feature with a somewhat indistinct outer rim that is little more than a slight ridge in the surface. The rim is better formed along the western and eastern sides. A small crater with a relatively high albedo lies along the inner wall to the northeast, and is surrounded by a small, bright skirt of ejecta. The interior floor is nearly featureless, with only a few indistinct small crater rims marking the surface.

Oberth (crater)

Oberth is a crater on the far side of the Moon. It lies in the high northern latitudes, to the southeast of the crater Gamow. To the east of Oberth is Avogadro.
