Kovalevskaya is a prominent lunar impact crater that is located on the far side of the Moon. It lies to the southwest of the larger walled plain Landau. To the south of Kovalevskaya are the craters Poynting and Fersman.

This crater overlies nearly half of the large Kovalevskaya Q along the southwest rim. The outer rim of Kovalevskaya is generally well-formed and not significantly eroded. The inner walls have formed terraces and slumped shelves in places. At the midpoint of the interior floor is a pair of central peaks that are split down the middle by a valley running north–south. Some hills run to the east of these peaks, and there are some low hills near the northwest inner wall. The remainder of the floor is relatively level and free from significant impacts.

This feature was named after the Russian mathematician Sofia Kovalevskaya (1850–1891). The asteroid 1859 Kovalevskaya is also named in her honour.^[1]

Zwicky is a lunar impact crater that is located on the far side of the Moon. It lies to the west of the crater Aitken, and is attached to the western rim of Vertregt. Attached to the northern end of Zwicky is Heaviside. Zwicky is a considerably eroded formation with an irregular rim and interior. Portions of the southern rim still survive, but the remainder has been almost completely eradicated.

Bettinus is a lunar impact crater located near the southwest limb. Due to its location, the crater has a distinctly oval shape because of foreshortening. To the south of the rim is the similar-sized crater Kircher, and to the northwest is the slightly smaller Zucchius. From the west to the southwest, closer to the limb, is the giant formation Bailly.

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.

Fizeau is a prominent lunar impact crater that is located on the far side of the Moon, in the southern hemisphere. Nearby craters of note include Minkowski to the west-northwest, and Eijkman to the southwest.

Ellison is a lunar impact crater that lies on the far side of the Moon from the Earth. It is located just beyond the northwest limb of the Moon, to the southwest of the large walled plain Poczobutt. Due west of Ellison is the crater Coulomb.

Brisbane is a lunar impact crater that is located in the southeastern part of the Moon, to the south of the crater Peirescius. To the northwest lie the craters Vega and Reimarus, and farther to the east is the walled plain Lyot. Due to its proximity to the limb, foreshortening of this crater causes it to appear somewhat elliptical in shape, even though it is actually circular.

Buffon is a lunar impact crater that is located on the southern hemisphere on the far side of the Moon. It lies a crater diameter south of the large walled plain Chebyshev. To the northeast is the crater Langmuir and to the southwest is Leavitt. Buffon lies nearly at the midpoint between these formations.

Chebyshev is a large lunar impact crater that lies in the southern hemisphere on the far side of the Moon. The somewhat smaller crater Langmuir is intruding into the east-southeastern rim of Chebyshev, forming a chain of large craters with Brouwer on Langmuir's eastern rim.

d'Alembert is a large lunar impact crater located in the northern hemisphere on the far side of the Moon, to the northeast of the somewhat smaller walled plain Campbell. Astride the southwest rim of d'Alembert is Slipher. To the north is the crater Yamamoto, and to the south-southwest lies Langevin. This walled plain has the same diameter as Clavius on the near side, making it one of the largest such formations on the Moon.

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.

Comstock is a lunar impact crater that is located on the far side of the Moon. It lies to the northeast of the walled plain Fersman, and north of the crater Weyl.

Finsen is a lunar impact crater that is located in the southern hemisphere, on the Moon's far side. It is attached to the southeastern exterior of the walled plain Leibnitz, and the ejecta from Finsen covers the southeastern part of Leibnitz's interior floor. To the southwest of Finsen is another walled plain, Von Kármán, partly overlain by Leibnitz.

Hirayama is a large lunar impact crater that is located on the far side of the Moon, just beyond the eastern limb. This region of the surface is sometimes brought into view from Earth during periods of favourable libration. However it is best viewed from orbit. This crater is located along the southeastern edge of the Mare Smythii, to the northeast of the crater Brunner. To the northeast of Hirayama is Wyld. On the west rim of Hirayama is the small, bright-rayed crater Bandfield.

Popov is a crater on the far side of the Moon, just beyond the eastern limb. It measures approximately 71.4 kilometers in diameter and is located along the very edge of the area of surface that is sometimes brought into view of the Earth during periods of favorable libration and illumination. However even at such times it is not prominent and can only be viewed edge-on.

Teisserenc is an eroded lunar impact crater on the Moon's far side. It lies just to the east of the crater Sanford, and southwest of Charlier. To the east of Charlier lies Kovalevskaya.
