Appleton is a heavily eroded lunar impact crater that lies in the northern hemisphere on the far side of the Moon. To the northwest are the craters Von Neumann and Campbel. The smaller Golovin lies to the northeast, while further to the southwest is the Mare Moscoviense.
The crater wall and interior have been heavily eroded by many subsequent impacts, leaving the features rounded and irregular. A pair of craters lie across the southwestern rim, and two small craterlets lie along the eastern rim. The interior floor is irregular and contains many tiny craterlets.
Appleton lies between a pair of satellite craters that are located on opposite sides of the rim, forming a triple formation. Appleton R is located just to the west-southwest, and contains another crater just inside its north rim. On the opposite side of Appleton is Appleton D, a comparably sized formation to Appleton R.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Appleton.

Phocylides is a lunar impact crater located near the southwest rim of the Moon. It overlays the south rim of the crater Nasmyth to the north. To the northwest is the unusual plateau formation of Wargentin. Eastward is the merged formation Schiller, and in the southwest lies Pingré.
Barrow is an old lunar impact crater that is located near the northern limb of the Moon. It lies between the crater Goldschmidt to the northwest and the irregular formation Meton to the northeast. To the southwest is W. Bond.
Doerfel is a lunar impact crater that is located in the vicinity of the southern pole, just on the far side of the Moon. It lies approximately midway between the large crater Hausen to the east-northeast and the even larger Zeeman to the southwest.
Dawson is a lunar impact crater that lies on the southern hemisphere on the far side of the Moon. It lies across a crater triplet: the southeast rim is intruding into the crater Alekhin; the northwest rim also intrudes into the larger satellite crater Dawson V, and the northeast rim is attached to the comparably sized Dawson D. To the south of this formation is the large crater Zeeman. West of Dawson is the crater Crommelin, and to the north lies Fizeau.
Boole is a lunar impact crater that lies along the northwestern limb of the Moon, to the northwest of the crater Gerard. At this location it is viewed nearly from the side, and is very oblong in shape due to foreshortening. The crater formation is nearly circular, however, with a wide inner wall that has been worn and rounded due to subsequent impacts. It is named after George Boole.
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.
Compton is a prominent lunar impact crater that is located in the northern hemisphere on the far side of the Moon. It lies to the east of the Mare Humboldtianum, and southwest of the walled plain Schwarzschild. To the southeast of Compton is the heavily eroded crater Swann.
Olivier is an old, eroded crater that is located in the northern hemisphere on the far side of the Moon. It lies in a region of dense cratering on all sides. To the east-southeast is a younger but comparably sized crater named Störmer. Southwest of Olivier is the crater Volterra.
Brianchon is a lunar impact crater that is located along the northwestern limb of the Moon. Due to its location, from the Earth the crater is seen from the edge and its visibility is somewhat affected by libration. Thus for a more detailed view, the crater must be viewed from orbit.
Barbier is a lunar impact crater that is located on the southern hemisphere on the far side of the Moon. It forms a matched pair with Cyrano to the north-northwest, and it lies to the southeast of the huge walled plain Gagarin. Southwest of Barbier is the crater Sierpinski, and to the southeast is the Mare Ingenii.
Bronk is an eroded crater that lies on the far side of the Moon, out of sight from the Earth. It lies to the southeast of the larger crater Kovalevskaya. Less than one crater diameter to the east-northeast is the smaller crater Bobone.
Playfair is a lunar impact crater that is located in the rugged southern highlands on the near side of the Moon. It was named after the Scottish geologist and mathematician John Playfair. It lies along the eastern rim of the eroded satellite crater Playfair G, a formation that is almost twice the diameter of Playfair itself. Playfair is nearly due north of the crater Apianus, and to the southwest of the Abenezra–Azophi crater pair.
Challis is a lunar impact crater that is located in the northern regions of the Moon's near side, close enough to the limb to appear significantly foreshortened when viewed from the Earth. It is joined to the crater Main through a break in the northern rim, and is close to Scoresby along the southeast side.
Coulomb is a lunar impact crater that lies behind the northwestern limb, on the far side of the Moon. It is located to the west-southwest of the large crater Poczobutt, and northeast of Sarton.
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.
Comrie is a lunar impact crater. It is located on the rugged far side of the Moon relative to the Earth, beyond the western limb. Nearby craters of note include Ohm to the south-southwest, Shternberg to the southwest, and Parenago to the northeast.
Ibn Firnas is a lunar impact crater on the far side of the Moon. In 1976 it was named after Abbas Ibn Firnas, a polymath from Andalucia who, in the 9th century, devised a chain of rings that could be used to simulate the motions of the planets and stars.
Evans is the remnant of a lunar impact crater that is located on the far side of the Moon. It lies to the south-southwest of the immense walled plain Hertzsprung, and is located within that impact basin's broad skirt of ejecta. This material has overflowed the northern rim of Evans and the northern part of the interior floor. The southern rim is not as heavily damaged, although it is irregular, eroded, and overlain by a pair of small craterlets. The most intact part of the rim is the southeastern section.
Lebedev is a crater on the far side of the Moon. It is located at the eastern edge of the irregular feature known as Mare Australe. The crater lies to the southeast of the larger, flooded Lamb, and to the east-northeast of Anuchin. To the southeast of Lebedev lies the smaller crater Cassegrain.
Paschen is a lunar impact crater on the far side of the Moon. The relatively large satellite crater Paschen M partly overlies the southern rim of Paschen, and they nearly form a merged pair with only a section of irregular terrain along their common border. The smaller but well-formed crater Paschen S lies across the southwestern rim of Paschen. As a result, most of the southern rim of Paschen is now gone.
