Zupus is the lava-flooded remains of a lunar impact crater. It is located on a southwestern reach of the Oceanus Procellarum, to the northwest of Mare Humorum. To the north-northeast is the flooded crater Billy, and some distance to the southeast is Mersenius. A system of faint rilles named the Rimae Zupus lie to the northwest, following a course to the north-northwest towards the mare.
Little remains of the original formation, and the rim is low and irregular in outline, giving the feature the appearance of a valley. This rim climbs to a maximum height of 1.3 km above the base. The crater Zupus S intrudes upon the eastern rim. A faint ghost crater lies in the mare to the northeast. The mare covering the floor of Zupus is darker in hue than the surrounding terrain, making the feature relatively easy for an observer to locate.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Zupus.

Fracastorius is the lava-flooded remnant of an ancient lunar impact crater located at the southern edge of Mare Nectaris. To the northwest of this formation lies the crater Beaumont, while to the northeast is Rosse.
Pitatus is an ancient lunar impact crater located at the southern edge of Mare Nubium. It was named after Italian astronomer Pietro Pitati by the IAU in 1935. Joined to the northwest rim is the crater Hesiodus, and the two are joined by a narrow cleft. To the south lie the attached Wurzelbauer and Gauricus.
Chacornac is an irregular lunar impact crater attached to the southeast rim of the crater Posidonius. It lies just to the east of the Mare Serenitatis, and north of the crater Le Monnier. The crater is named after French astronomer Jean Chacornac.
Catharina is an ancient lunar impact crater located in the southern highlands. It was named after Saint Catherine of Alexandria. It lies in a rugged stretch of land between the Rupes Altai scarp to the west and Mare Nectaris in the east. To the west-northwest is the crater Tacitus, and the lava-flooded Beaumont lies to the east along the shore of Mare Nectaris. To the south-southeast is Polybius.
Carrel is a small lunar crater on the Mare Tranquillitatis. It has a somewhat distorted appearance, having a slight protruding bulge in the northwest rim. The interior is somewhat irregular, with ridges and some slumped material. This crater lies across a ridge in the surface of the mare.
Flamsteed is a small lunar impact crater located on the Oceanus Procellarum, which is named after British astronomer John Flamsteed. It lies almost due east of the dark-hued Grimaldi, and north-northwest of the flooded Letronne bay on the south edge of the mare.
Prinz is the lava-flooded remains of a lunar impact crater on the Oceanus Procellarum. It was named after German-Belgian astronomer Wilhelm Prinz. The formation lies to the southwest of the prominent crater Aristarchus. To the north-northeast is the flooded crater Krieger.
Thomson is a lunar impact crater that is located within the Mare Ingenii on the far side of the Moon. Just to the northeast is the unusual merged crater formation of Van de Graaff. On the northwest rim of the mare is O'Day, and to the south-southwest is Obruchev on the southern shore of Mare Ingenii.
Abel is an ancient lunar impact crater that lies near the southeast limb of the Moon's near side. It is located to the south of the crater Barnard, at the northwest edge of the Mare Australe.
Belʹkovich is a large lunar impact crater of the form termed a walled plain. The formation has been heavily eroded by a history of subsequent impacts, leaving it reshaped, worn, and the features softened and rounded. Belʹkovich is located along the northeastern limb of the Moon, and so its visibility is subject to libration effects. From the Earth this crater is viewed from the side, making it difficult to view it in detail.
D'Arrest is a lunar impact crater that is located in the lava-flooded region to the west of the Mare Tranquillitatis. It is named after the German astronomer Heinrich Louis d'Arrest. It lies to the southeast of the crater Agrippa and northwest of Delambre. Just to the northeast are the small, bowl-shaped craters De Morgan and Cayley.
Bowditch is a lunar impact crater that lies on the far side of the Moon, just beyond the eastern limb. It is located on a region of the lunar surface that is brought into view due to libration, but at such times the area is viewed from the edge and so not much detail can be observed. It lies just to the north of the small Lacus Solitudinis lunar mare, between the craters Titius to the southwest and Perel'man to the east-northeast.
Cuvier is a lunar impact crater on the southern part of the Moon's near side. It is attached to the east-southeast rim of the unusually shaped formation Heraclitus. To the northeast is the crater Clairaut.
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.
Crozier is a lunar impact crater that is located on the southwest edge of Mare Fecunditatis, a lunar mare in the eastern part of the Moon's near side. It lies to the east-northeast of the prominent crater Colombo, and southeast of the small crater Bellot.
Elger is a lunar impact crater that lies along the southern edge of Palus Epidemiarum, the Marsh of Epidemics, in the southwest part of the Moon's near side. To the northeast is the flooded crater Capuanus, and farther to the northwest is Ramsden.
Fontana is a lunar impact crater that is located in the southwestern part of the Moon's near side, to the south of the Oceanus Procellarum. It lies to the west-northwest of the flooded crater Zupus. Midway between Fontana and Zupus is a rille system designated Rimae Zupus.
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.
Ginzel is a lunar impact crater that is located on the far side of the Moon, just beyond the eastern limb. It is named after the Austrian astronomer Friedrich Karl Ginzel. It lies at the eastern edge of the Mare Marginis, in a region of the surface that is sometimes brought into sight of the Earth due to libration. To the north-northeast of Ginzel is the crater Popov, and Dreyer lies due south.
Cassini is a lunar impact crater that is located in the Palus Nebularum, at the eastern end of Mare Imbrium. The crater was named after astronomers Giovanni Cassini and Jacques Cassini. To the northeast is the Promontorium Agassiz, the southern tip of the Montes Alpes mountain range. South by south-east of Cassini is the crater Theaetetus. To the northwest is the lone peak Mons Piton.
