Ross is a lunar impact crater that is located in the northwest part of the Mare Tranquillitatis. It was named after James Clark Ross (British explorer) and Frank E. Ross (American astronomer and optician). [1] It lies south-southwest of the crater Plinius, and northeast of the lava-flooded Maclear.
This crater has a generally circular shape, but is not quite symmetrical. The inner walls slope down to a base of slumped material, before joining a relatively level interior floor. There is a low ridge to the west of the crater midpoint.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Ross.

Cantor is a lunar impact crater that is located on the northern hemisphere on the far side of the Moon. The outer rim of the crater has a distinctly hexagonal shape, and is slightly longer in the north–south direction. The interior walls are multiply terraced, although less so along the western rim. There is a low central peak at the midpoint of the floor.
Bartels is a lunar impact crater located along the western perimeter of the Moon's visible face. At this location the crater is viewed from the side, and visibility is affected by libration. The crater can be viewed in its entirety only from lunar orbit. It is located to the north of the crater Moseley and south-southeast of Voskresenskiy.
De Vico is a small lunar impact crater that is located in the southwest part of the Moon, to the south of the crater Sirsalis. To the west-northwest is Crüger. De Vico is a circular, bowl-shaped formation with a small, flat bottom at the midpoint. To the northwest is the lava-flooded remains of De Vico T. Beyond is a linear rille designated Rimae Sirsalis that follows a path to the northeast past the rim of Sirsalis.
Burckhardt is a lunar impact crater that is located in the northeast part of the Moon. It lies between the craters Geminus just to the north and Cleomedes to the south.
Franklin is a lunar impact crater that is located in the northeast part of the visible Moon; it is named after Benjamin Franklin. To the north-northwest is the smaller crater Cepheus, and in the opposite direction to the southwest is the shallow Berzelius.
Anuchin is a lunar impact crater that lies on the southern hemisphere on the far side of the Moon. It is located to the south of the larger crater Lamb, and to the north-northwest of Kugler.
Boss is a lunar impact crater that is located along the northeast rim of the Moon's near side. Due to its location, the crater is viewed from the side by observers on the Earth, and its visibility is subject to libration effects.
Büsching is a lunar impact crater that is located in the crater-covered southern highlands of the Moon. It was named after German geographer Anton F. Büsching. The similar-sized crater Buch is located adjacent to its southwestern rim, and further to the southwest lies Maurolycus.
Bell is a lunar impact crater that is located on the far side of the Moon, just past the western limb. It lies in an area of terrain that is marked by many small craters, a number of which are satellite craters of Bell listed in the table below. Bell lies within two crater diameters of Laue to the north, and to the west of the smaller Helberg.
Ball is a lunar impact crater that is located in the rugged southern highlands of the Moon. It was named after British astronomer William Ball. The formation is circular and symmetrical, and has received little significant wear. The interior is rough-surfaced, curving downward toward the relatively wide central peak at the midpoint.
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.
Buisson is a lunar impact crater that is located on the far side of the Moon. It is named after the French physicist Henri Buisson. Nearly attached to the southeast rim is the crater Vesalius. To the southwest is Einthoven. The rim of this crater is somewhat worn, and is lowest in the north. There is a low central ridge across the midpoint.
Darney is a small lunar impact crater that is located on the region of the Moon where the Mare Nubium joins the Oceanus Procellarum. It was named after French astronomer Maurice Darney. To the south is the lava-flooded crater Lubiniezky. The southern rim of Darney is attached to a series of low ridges that extend to the southwest.
Bredikhin is a lunar impact crater that is located on the far side of the Moon. It lies just to the west of the crater Mitra, and northeast of Raimond.
De Forest is a lunar impact crater on the far side of the Moon. It is located in the far southern hemisphere, to the west of the large walled plain Zeeman and due south of the crater Numerov. Because of its proximity to the southern pole, this crater receives sunlight at an oblique angle when it is on the illuminated half of the Moon.
Carver is a lunar impact crater that is located on the far side of the Moon, due east of the walled plain Van der Waals. To the northeast is the crater Rosseland, and to the south-southeast lies Kozyrev.
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 to the northwest and southeast. What remains of the rim forms a rounded, somewhat irregular edge to the crater depression.
Fourier is a lunar impact crater that is located in the southwestern part of the Moon's near side, just to the southeast of the crater Vieta. To the northeast is the Mare Humorum. The rim of this crater is roughly circular, but appears oval when viewed from the Earth due to foreshortening.
Denning is a lunar impact crater that is located on the far side of the Moon. It lies about midway between the craters Levi-Civita to the south and Marconi to the north-northeast. About two crater diameters to the southeast is the huge walled plain Gagarin.
Eijkman is a lunar impact crater that is located on the far side of the Moon's southern hemisphere. It lies about a half crater diameter to the southeast of the larger crater Lemaître. To the south-southwest is the crater Crommelin, and to the northeast is Fizeau.
