Bayer is a lunar impact crater located in the southwest section of the moon, to the east of the crater Schiller. The rim of Bayer is slightly worn by erosion, but remains well-defined. There is an inner terrace, but the outer wall is intruded upon by nearby impacts. The most significant of these is Schiller H, which forms a ridge attached to the northwest rim of Bayer. The floor of Bayer is relatively flat and lacks a central peak. There is a small, but notable crater on the floor near the western wall. This crater has a breach in its northern rim.
Cavalerius is a prominent lunar impact crater that lies on the western edge of the Oceanus Procellarum lunar mare on the west part of the visible Moon. It nearly joins the northern rim of Hevelius to the south.
Bianchini is a lunar impact crater that lies along the northern Jura Mountains that ring the Sinus Iridum, in the northwestern part of the near side of the Moon. It was named after Italian astronomer Francesco Bianchini. The impact of this crater near the edge of the Jura Mountains deposited some material into the Sinus Iridum floor.
Doppler is a lunar impact crater named for Christian Doppler that is located at the southern edge of the walled plain Korolev, on the far side of the Moon. To the east are the craters Das and Galois. Farther to the southwest of Doppler is Mohorovičić.
Alekhin is a lunar impact crater that is located on the southern hemisphere on the far side of the Moon. It lies to the north of the crater Zeeman, and south-southeast of Fizeau. To the west lies Crommelin, and east-southeast is Doerfel.
Behaim is a lunar impact crater that is located near the eastern limb of the Moon, just to the south of the crater Ansgarius. To the south of Behaim is the crater Hecataeus, and to the east-southeast is Gibbs.
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.
Carnot is a large crater in the northern part of the Moon's far side. It was named after Nicolas L. S. Carnot by the IAU in 1970.
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.
Coriolis is a lunar impact crater that is located on the far side of the Moon. The crater floor is bisected by the lunar equator, and it lies about three crater diameters northwest of the crater Daedalus.
Cyrano is a lunar impact crater that lies on the far side of the Moon. It lies due east of the huge walled plain Gagarin, and to the north of the somewhat smaller crater Barbier.
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.
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.
Chang Heng is a lunar impact crater that is located on the Moon's far side. It lies less than one crater diameter to the northeast of the walled plain Fleming. The rim of this crater is somewhat eroded, with a pair of small craters along the northern rim and tiny craters along the south and east edges. The interior floor contains a small, concentric crater that is about one third the diameter of Chang Heng. The crater is named after Chinese astronomer Zhang Heng.
Fraunhofer is a lunar impact crater that is located just to the south-southwest of the walled plain Furnerius, in the southeastern part of the Moon. This crater appears foreshortened when viewed from the Earth, and is actually nearly circular.
Ibn Firnas is a lunar impact crater on the far side of the Moon. Attached to the exterior of its southwestern rim is the prominent crater King. Only a few kilometers to the north, separated by a rugged stretch of terrain, is the larger crater Ostwald.
Donner is a lunar impact crater on the far side of the Moon. It is located just to the northeast of the Mare Australe, behind the southeastern limb of the Moon. During favorable librations this part of the lunar surface can be brought into view of the Earth, but the site is viewed from the edge and so not much detail can be seen.
Emden is a lunar impact crater that is located in the northern hemisphere on the far side of the Moon. It is named after Jacob Robert Emden (1862-1940).
Foster is a small lunar impact crater that lies to the southeast of the larger crater Joule, on the far side of the Moon. The rim of Foster is slightly eroded, and the narrow inner walls slope directly down to the relatively dark interior floor. The rim has a small outward bulge along the southwest side. There is a small craterlet on the floor next to the northern rim. A tiny impact in the southeast part of the crater interior is surrounded by a small skirt of high albedo material, producing a bright patch.
Fridman is the remains of a lunar impact crater on the far side of the Moon. It lies due south of the huge walled plain Hertzsprung, and is attached to the northeastern rim of the crater Ioffe.
