Aryabhata, named after Indian astronomer Aryabhata, is the remnant of a lunar impact crater located in the eastern Mare Tranquillitatis. The crater has been almost submerged by lava-flow, and now only an arc-shaped ridge formed from the eastern half of the rim remains above the lunar mare. This crater was previously identified as Maskelyne E before being named by the IAU in 1979. Maskelyne itself is to the southwest.
Atwood is a small earth moon impact crater that is located on the Mare Fecunditatis, to the northwest of the prominent crater Langrenus. It forms a triple-crater formation with Naonobu attached to the north rim and Bilharz near the west rim.
Zhiritskiy is a lunar impact crater that is located on the far side of the Moon. It lies to the south of the large walled plain Fermi, and northwest of the crater Schaeberle.
Gilbert is a large lunar impact crater that lies near the eastern limb of the Moon. Due to its location this feature appears foreshortened when viewed from the Earth, limiting the amount of detail that can be observed. The crater lies to the northwest of the similar-sized walled plain Kästner, to the west of the Mare Smythii.
Fermi is a large lunar impact crater of the category named a walled plain. It was named after Italian-American physicist and Nobel laureate Enrico Fermi. It lies on the far side of the Moon and can not be viewed from the Earth. Thus this feature must be viewed from an orbiting spacecraft.
Kästner is a lunar impact crater that is located near the eastern limb of the Moon, to the southwest of the Mare Smythii. Just to the northwest of Kästner is the walled plain Gilbert. To the south is the prominent crater Ansgarius, and to the southwest lies La Pérouse.
Weierstrass is a small lunar impact crater that is attached to the northern rim of the walled plain Gilbert, in the eastern part of the Moon. It also lies very near the crater Van Vleck, a similar formation just to the southeast that is almost attached to the outer rim. Due to its location, the crater appears foreshortened as seen from the Earth.
Van Vleck is a lunar impact crater that is located near the northeastern rim of the walled plain Gilbert, to the west of the Mare Smythii. The similar crater Weierstrass is nearly joined to the northwestern rim of Van Vleck. To the east is the small Carrillo.
Lebesgue is a small lunar impact crater that is located near the eastern limb of the Moon. It lies in the southeastern part of the Mare Smythii, to the southeast of the crater Warner. The southeastern rim of Lebesgue is attached to a small crater that overlays the northwest rim of Swasey, so that the three form a short crater chain. This is a circular, bowl-shaped crater formation. It is not notably eroded or overlain by impacts.
Runge is a lunar impact crater in the Mare Smythii, along the eastern edge of the Moon. It lies less than one crater diameter to the north-northwest of the very similar crater Warner. To the west-northwest is Haldane, and due west is the smaller Talbot.
Swasey is a small lunar impact crater that lies along the eastern limb of the Moon. It lies near the southeastern edge of the Mare Smythii, to the west of the walled plain Hirayama. About one crater diameter to the northeast is Hume, and to the southwest is the merged crater pair of Kao and Helmert.
Warner is a lunar impact crater that is located in the southern part of the Mare Smythii, near the eastern limb of the Moon. In this location the crater is viewed almost from the edge from Earth, and is sometimes hidden from sight due to libration. The crater lies just to the south-southeast of the very similar Runge. To the southwest is Widmannstätten, and to the south is the merged Kao–Helmert crater pair.
Danjon is a lunar impact crater on the far side of the Moon. It lies less than a crater diameter to the east-southeast of the larger crater Langemak. To the east-northeast of Danjon is the crater Perepelkin, and due south lies the walled plain Fermi.
D'Arsonval is a small lunar impact crater on the far side of the Moon. It is situated across the northeastern rim of the older and larger crater Danjon. To the west of D'Arsonval is Perepelkin.
Delporte is a lunar impact crater on the far side of the Moon. It overlies part of the northwestern rim of the huge walled plain Fermi, and the crater Litke is nearly attached to the southeastern rim.
Dobrovolʹskiy is a small lunar impact crater on the Moon's far side. The northwest part of its rim is intruded upon by the somewhat larger crater Shirakatsi, and the outer rampart of that feature covers most of the interior floor of Dobrovolʹskiy. Very little of the original floor now survives, with a small section near the southern inner wall. The remainder of the crater rim is somewhat circular and only mildly worn.
Litke is a lunar impact crater that lies within the large walled plain Fermi, near the north-northwestern inner rim. Less than one crater diameter to the west-northwest is the slightly larger Delporte. Litke is located on the far side of the Moon and cannot be viewed directly from the Earth.
Volkov is a lunar impact crater on the Moon's far side. It is located to the north of the prominent crater Tsiolkovskiy, and east-southeast of Dobrovol'skiy. Overlying the southeastern rim of Volkov is the satellite crater Volkov J, and the two have merged to form a figure-8 shape. The crater Lander is attached to the southwest rim of Volkov J, making this a triple-crater formation.
Langemak is a prominent impact crater on the far side of the Moon. It is located less than one crater diameter west-northwest of Danjon, and nearly due east of Meitner. To the southwest of Langemak is Kondratyuk. Langemak partly overlies the larger and older crater Langemak N. This feature is also attached to the northeastern rim of Kondratyuk.
Waterman is a lunar impact crater that is located on the Moon's far side, and cannot be viewed directly from the Earth. It lies along the southern outer ramparts of the prominent crater Tsiolkovskiy. Almost attached to the southwest is Neujmin, so that Waterman lies straddled between these two features.
