Blackett is a lunar impact crater that lies on the far side of the Moon, behind the southwest limb. It lies beyond the southeast outer ring of the immense Mare Orientale basin. The formation of that major feature has left Blackett deeply marked with ridge features trending from the northwest. Much of the crater has been shaped by the ejecta from Mare Orientale, particularly along the western half of the crater.

Overall this crater is heavily eroded, with several craters overlaying the southern rim, and smaller formations overlaying the western and northwestern rim. The interior floor has been roughened by ejecta, leaving only parts of the southwest interior in their previous relatively level and featureless condition.

The crater Stetson lies on the southwest rim.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Blackett.

Riccioli (crater)

Riccioli is a lunar impact crater located near the western limb of the Moon. It lies just to the northwest of a larger crater, Grimaldi. To the southwest are the craters Hartwig and Schlüter that lie on the northeastern edge of Montes Cordillera, a ring-shaped range that surrounds Mare Orientale. Due to its location, Riccioli appears strongly foreshortened from the earth and is viewed almost from the side.

Hohmann (crater)

Hohmann is a lunar impact crater that lies within the central basin of the Mare Orientale formation, on the farside of the Moon. It is located to the south of the crater Maunder, and to the west of Kopff crater. Due to its proximity to the western lunar limb, this area of the surface is occasionally visible during favorable librations. However the basin is viewed from the side, restricting the amount of detail that can be observed from Earth.

Lagrange is a lunar impact crater that is attached to the northwestern rim of the crater Piazzi. It lies near the southwestern limb of the Moon, and the appearance is oblong due to foreshortening. To the northwest of this feature is the Montes Cordillera, a ring-shaped mountain range that surrounds the immense Mare Orientale impact basin.

Catalán (crater)

Catalán is a small lunar impact crater that lies almost along the southwest limb of the Moon. At this position the crater is ill-suited for observation from the Earth as it is viewed almost from the side, and visibility is subject to libration effects. It lies to the west of the somewhat larger crater Baade, and south-southeast of Graff. This region is located in the outer southeastern part of the skirt of ejecta that surrounds the Mare Orientale impact basin, and the nearby surface is rugged and streaky. This crater is named after the Spanish scientist Miguel Antonio Catalán Sañudo (1894–1957) for his contributions to spectroscopy, an important exploratory tool in astronomy.

Chant (crater)

Chant is a lunar impact crater that is located on the far side of the Moon, behind the southwest limb as seen from the Earth. It lies within the southwestern part of the blanket of ejecta surrounding the Mare Orientale, beyond the Montes Cordillera mountain ring. To the west-northwest is the large walled plain Blackett. Southward is the crater Mendel.

Chadwick (crater)

Chadwick is a lunar impact crater that lies on the far side of the Moon's surface, just beyond the southwestern limb. It is located to the northwest of the crater De Roy, and was previously designated De Roy X before being given its current name by the IAU. This region of the lunar surface lies at the southern end of the ejecta blanket that surrounds the Mare Orientale impact basin.

Inghirami (crater) Lunar impact crater

Inghirami is a lunar impact crater that is located toward the southwestern limb of the Moon. It lies to the southwest of the large walled plain Schickard. Northwest of Inghirami is the wide Vallis Inghirami, a wide, straight valley that is radial to the Mare Orientale impact basin. The valley has a length of about 140 kilometers and ends at the northern edge of the crater.

Hartwig (lunar crater)

Hartwig is a lunar impact crater that is located near the western limb of the Moon. It is attached to the eastern rim of the prominent crater Schlüter, to the northeast of the Montes Cordillera mountain range that surrounds the Mare Orientale. To the east-northeast of Hartwig is the larger crater Riccioli.

Chalonge (crater)

Chalonge is a lunar impact crater that is located on the far side of the Moon. It lies to the southwest of the larger crater Lewis, in the outer skirt of ejecta that surrounds the Mare Orientale impact basin. To the southeast are the Montes Cordillera, a ring of mountains that encircle the Mare Orientale formation.

Steklov (crater)

Steklov is a lunar impact crater on the far side of the Moon, past the southwestern limb. It lies in the outer skirt of ejecta from the Mare Orientale impact basin, just to the southwest of the Montes Cordillera ring of mountains. About four crater diameters to the southwest is the slightly smaller crater Chant.

Elvey (crater) Lunar impact crater

Elvey is a lunar impact crater that is located on the far side of the Moon. It is located near the northern edge of the blanket of ejecta that surrounds the Mare Orientale impact basin. To the north of Elvey is the smaller crater Nobel.

Fényi (crater)

Fényi is a small lunar crater on the far side of the Moon. It lies near the southern edge of the huge, braided skirt of ejecta that surrounds the Orientale impact Basin to the north. Less than two crater diameters to the southwest is the much larger crater Mendel.

Fridman (crater)

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.

Gerasimovich (crater) Lunar impact crater

Gerasimovich is a lunar impact crater on the far side of the Moon. It lies beyond the western limb, to the west-northwest of the immense Mare Orientale impact basin. The outer blanket of ejecta from this impact reaches nearly to the rim of Gerasimovich. Nearby craters of note include Houzeau to the north and the smaller Ellerman to the southeast.

Mendel (lunar crater)

Mendel is a large Impact crater that lies on the far side of the Moon. It is located in the southern fringe of the huge skirt of ejecta that surrounds the Mare Orientale impact basin. To the south-southwest of Mendel is Lippmann, an even larger crater.

Houzeau (crater)

Houzeau is a lunar impact crater on the far side of the Moon. It is located to the northwest of the Mare Orientale impact basin, and ejecta from that event has fallen across this crater rim and its interior. To the south of Houzeau lies the crater Gerasimovich, and one crater diameter to the west is Belopol'skiy. To the northwest lies Fridman, with Ioffe to its southwest.

Lippmann (crater)

Lippmann is a large lunar impact crater in the southern part of the far side of the Moon and so cannot be viewed directly from the Earth. Just to the northeast is the walled plain Mendel, only slightly smaller than Lippmann. To the south-southeast lies the crater Petzval.

Stetson (crater)

Stetson is the remains of a crater on the far side of the Moon. The northeastern part of the rim of Stetson has been overlain by the larger crater Blackett. Lying across the eastern rim is a double-crater formation consisting of the satellites Stetson E and Stetson G. There are also small craters along the southeast and northwestern rims.

Leuschner (crater)

Leuschner is a lunar impact crater that is located on the Moon's far side, to the northwest of the Montes Cordillera. It lies to the north of the crater Grachev, in the outer skirt of ejecta surrounding the Mare Orientale impact basin. This is a circular crater with a rim that has only been lightly eroded by subsequent impacts. Within the interior floor is a central ridge formation.

Nobel (crater)

Nobel is a crater that lies on the far side of the Moon. It is located in the northern edge of the vast skirt of ejecta surrounding the Mare Orientale impact basin. Less than three crater diameters to the south of Nobel is the larger crater Elvey, and to the west-southwest is the smaller Pease. This is a circular, bowl-shaped crater with a worn outer rim. Three smaller craters overlie the northern rim. The interior floor is relatively level, and is marked by several small and tiny craterlets.
