Eponym F. Capuano di Manfredonia

Capuanus is a lunar impact crater that lies along the southern edge of the Palus Epidemiarum. It was named after Italian astronomer F. Capuano di Manfredonia. [1] The outer rim is eroded and indented by lesser crater impacts, with notches in the north, west, and southern parts of the rim. The interior floor has been resurfaced by basaltic lava, which is connected to the surrounding lunar mare by a narrow, crater-formed gap in the northern rim. Dotting the floor of the crater are a number of domes, which are believed to have formed through volcanic activity.

The rim reaches its maximum altitude along the western face, where it merges with ridges along the edge of the mare. To the northeast the rim dips down very close to the surface, and barely forms a curving ridge in the surface. The southeastern rim is overlaid by a pair of craters.

To the north of Capuanus is the western extreme of the wide rille named Rima Hesiodus, which runs to the east-northeast. To the west-northwest is the crater Ramsden, and between Capuanus and Ramsden lies a system of intersecting rilles named the Rimae Ramsden.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Capuanus.

Anaximenes (crater)

Anaximenes is a low-rimmed lunar impact crater near the north-northwest limb of the Moon. It lies to the west of the crater Philolaus, and northeast of Carpenter. To the northwest is Poncelet, close to the visible edge of the Moon.

Cleomedes (crater)

Cleomedes is a prominent lunar impact crater located in the northeast part of the visible Moon, to the north of Mare Crisium. It was named after Greek astronomer Cleomedes. It is surrounded by rough ground with multiple crater impacts. The irregular crater Tralles intrudes into the northwest rim. To the east is Delmotte. North of Cleomedes is a triple-crater formation with Burckhardt occupying the center.

Cardanus (crater)

Cardanus is a lunar impact crater that is located in the western part of the Moon, in the western part of the Oceanus Procellarum. Due to its location the crater appears very oval because of foreshortening, and it is viewed almost from the side.

Cavalerius (crater)

Cavalerius is a prominent lunar impact crater that lies on the western edge of the Oceanus Procellarum lunar mare on the west part of the visible Moon. It nearly joins the northern rim of Hevelius to the south.

Doppelmayer (crater)

Doppelmayer is the remains of a lunar impact crater that lies on the southwest edge of Mare Humorum. It was named after the German mathematician and astronomer Johann Gabriel Doppelmayr. To the south-southeast is another flooded crater designated Lee, and to the southeast is Vitello. Just to the east-northeast of Doppelmayer lies the nearly submerged crater Puiseux.

Abel (crater)

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.

Archytas (crater)

Archytas is a lunar impact crater that protrudes into the northern edge of Mare Frigoris. To the northwest is the comparably sized crater Timaeus, and the smaller Protagoras lies in the opposite direction to the southeast. Further to the southwest, beyond the opposite edge of the mare, is the dark-floored crater Plato.

Belkovich (crater)

Bel'kovich 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. Bel'kovich 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.

Bowditch (crater)

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.

Fontenelle (crater)

Fontenelle is a lunar impact crater that is located along the northern edge of Mare Frigoris, in the northern part of the Moon. To the northeast is the remnant of the crater Birmingham. Due to its location, this crater appears oval in shape when observed from the Earth because of foreshortening.

Cuvier (crater)

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.

Campanus (crater) Lunar impact crater

Campanus is a lunar impact crater that is located on the southwestern edge of Mare Nubium. It was named after Italian astronomer Campanus of Novara. It forms a crater pair with Mercator just to the southeast. Along the southern rampart of Campanus is the small lunar mare named Palus Epidemiarum. To the southwest is the small crater Dunthorne.

Casatus (crater) Lunar impact crater

Casatus is a lunar impact crater that is located near the southern limb of the Moon. The north-northeast rim of the crater overlies a portion of the slightly larger crater Klaproth. Along the western rim, Casatus A intrudes somewhat into the interior, producing an inward-bowing rim. To the southeast of Casatus is Newton.

Riemann (crater)

Riemann is a lunar impact crater that is located near the northeastern limb of the Moon, and can just be observed edge-on when libration effects bring it into sight. It lies to the east-northeast of the large walled plain Gauss. To the southeast, beyond sight on the far side, is the crater Vestine.

Crozier (crater)

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 (crater) Lunar impact crater

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.

Williams (lunar crater)

Williams is the remnant of a lunar impact crater that lies to the south of the prominent crater Hercules, in the northeastern part of the Moon. The southern rim borders the Lacus Somniorum, a small lunar mare that extends to the south and west. To the southwest is the sharp-rimmed crater Grove.

Fourier (crater) Lunar impact crater

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.

Donner (crater)

Donner is a lunar impact crater on the far side of the Moon. It is located just to the northeast of the Mare Australe, behind the southeastern limb of the Moon. During favorable librations this part of the lunar surface can be brought into view of the Earth, but the site is viewed from the edge and so not much detail can be seen.

Dreyer (crater)

Dreyer is the remnant of a lunar impact crater on the far side of the Moon. It is located along the eastern edge of the Mare Marginis, about midway between the craters Ginzel to the north and Erro to the south-southeast. It was named after Danish-Irish astronomer John L. E. Dreyer.
