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.
Avery is a small lunar impact crater located near the eastern limb of the Moon. This is a circular, bowl-shaped formation with a small interior floor. It lies near the western edge of Mare Smythii. To the east is the crater Haldane, and to the southwest is Carrillo. Gilbert lies to the southwest.
Beketov is a small lunar impact crater that lies in the northern reaches of the Mare Tranquillitatis. It is named after Russian chemist Nikolay Beketov. To the south is the ghost crater Jansen R. Northeast of Beketov, along the edge of the mare, is the crater Vitruvius. Beketov was previously designated Jansen C before being named by the IAU. The flooded crater Jansen itself lies to the south.
Carrillo is a small lunar impact crater located near the eastern limb of the Moon. In this location the crater is subject to lunar libration effects, and appears highly oval due to foreshortening. It is located on the slope of highlands on the west side of Mare Smythii, and its inner wall is wider on the western side than to the east.
Curtis is a very small lunar impact crater that lies in the western Mare Crisium, to the east of the crater Picard. It is a circular, cup-shaped formation that is otherwise undistinguished. It was named after American astronomer Heber D. Curtis in 1973. In the past it was designated Picard Z.
Proclus is a young lunar impact crater located to the west of the Mare Crisium, on the east shore of the Palus Somni. Its diameter is 27 km. It was named after 5th century Greek mathematician, astronomer and philosopher Proclus.
Auzout is a lunar impact crater that is located to the southeast of the Mare Crisium, near the eastern limb of the Moon. It is named after French astronomer Adrien Auzout."Auzout (crater)". Gazetteer of Planetary Nomenclature. USGS Astrogeology Research Program. Attached to the southern rim is the smaller crater van Albada. To the east-northeast is the large Condorcet. This crater is not especially notable, although it does possess a central mountain. This crater is designated 'Azout' in some sources.
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.
Condon is a lunar impact crater that lies on the eastern shore of the Sinus Successus, a bay along the northeast edge of Mare Fecunditatis. It was named after American physicist Edward U. Condon in 1976. It lies midway between the larger crater Apollonius to the north and the smaller Webb to the south on the Mare Fecunditatis. Condon was previously designated Webb R.
Fredholm is a small lunar impact crater that is located in the rugged ground to the west of the Mare Crisium. It was named after Swedish mathematician Erik I. Fredholm. It was previously designated Macrobius D. It lies midway between the prominent craters Macrobius to the north and Proclus almost due south.
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.
Widmannstätten is a lunar impact crater in the southern part of the Mare Smythii, near the eastern limb of the Moon. The rim of this crater has a wide gap along the western side, where it is joined to the larger Kiess. There is also a gap in the northern rim where the crater floor is joined to the adjacent lunar mare. The dark interior floor of this formation has been flooded by lava, leaving a level interior surface and a shallow surviving rim.
Kao is a small lunar impact crater that is located near the eastern limb of the Moon. It lies near the southern edge of the Mare Smythii, a lunar mare that continues onto the far side of the surface. This crater lies to the east-southeast of the crater Widmannstätten. Less than a crater diameter to the north-northeast is the small crater Tucker.
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.
Talbot is a small lunar impact crater on the Mare Smythii, near the eastern limb of the Moon. It lies between a pair of larger, flooded craters, with Runge to the west and Haldane to the west-northwest. The crater is entirely surrounded by the dark lunar mare. It is a circular, bowl-shaped formation with an almost featureless interior floor. The outer rim has a slightly higher albedo than the surrounding terrain, but the floor is as dark as the mare.
Tucker is a small lunar impact crater in the southern part of the Mare Smythii. It is located along the eastern limb of the Moon, and from the Earth it is seen nearly from the edge. It lies between the slightly larger crater Lebesgue to the northeast and the flooded Kao to the south-southwest.
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.
Slocum is a small lunar impact crater in the southeastern part of the Mare Smythii. It lies near the eastern limb of the Moon, and from the Earth this section of the surface is viewed at a very oblique angle. This greatly limits the amount of detail that can be observed. In addition, libration of the Moon in its orbit can cause this area to be completely hidden from Earth. Nearby craters of note include Runge to the west-northwest, Warner to the west-southwest, and Swasey to the south-southeast.
