Chappell is a lunar impact crater on the far side of the Moon, in the northern hemisphere just to the north of the crater Debye. It is in a heavily bombarded section of the surface, and much of its outer rim is overlain by smaller craters. The northern rim in particular has been almost completely disintegrated, while small craters also overlie the rim
Bergstrand is a lunar impact crater that lies on the far side of the Moon. It is located just to the southeast of the prominent crater Aitken, and northeast of the walled plain Vertregt. The rim of Bergstrand is roughly circular, except along the southwest where the larger satellite crater Bergstrand Q intrudes into the outer wall. With one small craterlet covering the southern
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. The outer rim of this crater has been worn and eroded, particularly along the northwest half. The most intact part
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
Bjerknes is a lunar impact crater that is located in the southern hemisphere on the rugged far side of the Moon. The crater lies behind the southeastern limb, and beyond the region that is sometimes brought into sight through libration. Thus this crater can not be viewed from Earth, and has only been seen from orbit. Nearby named craters are Clark to the east, and Pogson to the south-southwest. The
Bok is a lunar impact crater that is located on the far side of the Moon. To the southeast is the crater Sniadecki; to the north is McKellar, and further to the west is De Vries. The rim of Bok is well-defined and is not significantly eroded. The inner walls slope gently down to the nearly level interior floor, which has a central peak near
Belopolʹskiy 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 Belopolʹskiy is the crater Ioffe. The rim of Belopolʹskiy is somewhat eroded, particularly at the southern end where several small craterlets have worn away the rim edge. There is a slight
Belʹkovich is a large lunar impact crater of the form termed a walled plain. The formation has been heavily eroded by a history of subsequent impacts, leaving it reshaped, worn, and the features softened and rounded. Belʹkovich is located along the northeastern limb of the Moon, and so its visibility is subject to libration effects. From the Earth this crater is viewed from the
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
Apollo, also called the Apollo basin, is an enormous impact crater located in the southern hemisphere on the far side of the Moon. This formation dwarfs the large crater Oppenheimer that is located next to the western rim. The crater Barringer lies across the northern wall. To the southeast is the crater Anders, and Kleymenov is just to the east of the rim. Apollo Oblique Lunar Orbiter 5 image Coordinates 36.1°S 151.8°W
