Maraldi is a worn, eroded crater on the western edge of the Sinus Amoris, in the northeast part of the Moon. To the west-southwest is the crater Vitruvius, and to the northwest lies the worn Littrow crater. Just to the northeast of the crater is the dome-like Mons Maraldi rise.

Contents

The crater is named after two Italian-born French astronomers: Giovanni Domenico Maraldi and Giacomo F. Maraldi. [1]

Maraldi has a very worn outer wall that is deeply incised and has the appearance of a circular range of peaks rather than a crater rim. The interior has been flooded with basaltic lava, leaving a flat surface with a low albedo. There is a low ridge just to the northwest of the midpoint, and several tiny craters mark the floor surface.

Maraldi is a crater of Nectarian age. [2]

Satellite craters

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

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.

<span class="mw-page-title-main">Argelander (crater)</span> Crater on the Moon

Argelander is a lunar impact crater that is located in the south-central highlands of the Moon. It was named after the German astronomer Friedrich Argelander. It lies in the midpoint between the smaller crater Vogel in the north and the larger Airy to the south. To the northwest is the worn remnant of Parrot. Just to the west is a shallow cleft in the surface that follows a course to the north-northwest, intersecting the southeast rim of Parrot.

<span class="mw-page-title-main">Scott (crater)</span> Lunar surface depression

Scott is a lunar impact crater near the south pole of the Moon. Its location close to the lunar limb hinders observation, both from the foreshortening of the crater as seen from Earth and from the limited sunlight that enters the basin. The northern end of this crater is in near perpetual darkness, and has not been mapped in detail. Scott lies between the similar-sized crater Amundsen to the southeast and Schomberger to the northwest. Just to the northeast is the crater Demonax.

<span class="mw-page-title-main">Alexander (crater)</span> Crater on the Moon

Alexander is a lunar impact crater-like feature in the rugged surface to the north of Mare Serenitatis. It lies to the south-southwest of the prominent crater Eudoxus, and to the east-northeast of Calippus. It was named after Alexander the Great.

<span class="mw-page-title-main">Boss (crater)</span> Lunar impact crater

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. It was named by the IAU in 1964 for astronomer Lewis Boss.

Crommelin is an ancient lunar impact crater that is located in the vicinity of the south pole of the Moon, on the far side. It lies to the north of the large crater Zeeman, and to the east-northeast of Numerov.

<span class="mw-page-title-main">Buch (crater)</span> Crater on the Moon

Buch is an old, worn crater that is located in the rugged southern highlands of the Moon. It was named after German geologist Leopold von Buch. It lies to the northeast of the large crater Maurolycus, and the comparably sized crater Büsching is attached to the northeast rim.

<span class="mw-page-title-main">Fechner (crater)</span> Lunar surface depression

Fechner is a lunar impact crater that lies on the far side of the Moon's southern hemisphere, attached to the western rim of the large walled plain Planck. The eastern rim of Fechner intersects the Vallis Planck, a long, wide cleft in the surface that follows a course to the north-northwest. This valley intrudes into the southeastern rim of the crater, then continues northwards from the periphery of the northeast rim.

<span class="mw-page-title-main">Becquerel (lunar crater)</span> Lunar impact crater

Becquerel is a lunar impact crater that lies in the northern hemisphere on the far side of the Moon. This is an ancient and heavily worn formation that is now little more than an irregular buri in the surface. The outer rim has been worn and reshaped until it forms a rugged, mountainous region around the flatter interior.

<span class="mw-page-title-main">Fabry (crater)</span> Impact crater

Fabry is a large lunar impact crater of the form termed a walled plain. It is located on the far side of the Moon, just beyond the northeastern limb. Parts of this area are sometimes brought into view by the effects of libration, but the terrain is seen from the edge and so not much in the way of detail can be observed.

Breislak is a lunar impact crater that lies within one crater diameter north-northwest of the crater Baco, in the southern part of the Moon. To the north-northwest is the crater Barocius, and to the west lies Clairaut. This crater was named in honor of geologist Scipione Breislak.

<span class="mw-page-title-main">Rayleigh (lunar crater)</span> Crater on the Moon

Rayleigh is a lunar impact crater, approximately 114 kilometers in diameter, that lies along the northeast limb of the Moon. This feature is seen edge-on from Earth, making it difficult to see much detail. In addition, libration effects can completely hide this crater from view. It lies just to the north of Lyapunov, and to the northwest of the large Joliot. Attached to its southwest rim is the smaller Urey.

Theophrastus is a small lunar impact crater at the southern part of the Sinus Amoris, a bay at the northeast part of the Mare Tranquillitatis. It was named after ancient Greek philosopher Theophrastus in 1973. It lies to the southeast of the lava-flooded crater Maraldi, and was designated Maraldi M until the IAU gave it its current name. Just to the southeast of Theophrastus is the flooded Franz.
