Eponym Wallace J. Eckert

Eckert is a tiny, isolated lunar impact crater in the northern part of the Mare Crisium (a circular region of relatively dark, flat material on the surface of the Moon). This crater forms a circular pit in the dark surface of the surrounding lunar mare. Just to the west is a wrinkle ridge in the mare surface, a feature that is prominent only under oblique lighting from the Sun. The nearest craters of note are Peirce to the west-northwest, and Picard to the southwest. Both of these craters lie in the Mare Crisium basin.

The crater is named for American astronomer Wallace John Eckert, and name was approved by the IAU in 1973. [1]

Artsimovich (crater)

Artsimovich is a small lunar impact crater located in the western Mare Imbrium of the Earth's Moon. This is a circular crater forming a cup-shaped excavation in the surface of the lunar mare. It is named after Soviet physicist Lev A. Artsimovich. To the east is the crater Diophantus and to the northeast lies Delisle. Less than 20 kilometers to the north-northeast is the tiny Fedorov. This crater was identified as Diophantus A before being named by the International Astronomical Union.

Fahrenheit (crater)

Fahrenheit is a tiny lunar impact crater located in the southeast part of the Mare Crisium. This area of the surface is nearly devoid of impact features of interest. To the east are the Dorsa Harker wrinkle ridges, and beyond them is Promontorium Agarum at the edge of the mare. The landing site of the Soviet Luna 24 probe is located about 15 kilometers to the southeast.

Amontons (crater)

Amontons is a tiny lunar impact crater in the western half of the Mare Fecunditatis. It is a circular, cup-shaped formation that has been excavated out of the level surface by the impact, and is the same dark hue as the surrounding mare. When the sun is at a low angle, multiple ghost-craters are visible in the mare surface to the south-southeast and north of it.

Abbot (crater) Lunar impact crater

Abbot is a small lunar impact crater that lies on the rugged ground between the Mare Fecunditatis in the south and west, and the Mare Crisium to the north. It is a circular crater with a cup-shaped interior. The inner walls slope downward to the midpoint, and no impacts of significant mark the interior or the rim.

Crile (crater)

Crile is a tiny lunar impact crater. It is roughly circular and cup-shaped, with interior walls that slope down to the midpoint. The crater lies in the Palus Somni, between the Mare Crisium to the east and Mare Tranquillitatis to the west.

Curtis (crater)

Curtis is a very small lunar impact crater that lies in the western Mare Crisium, to the east of the crater Picard. It is a circular, cup-shaped formation that is otherwise undistinguished. It was named after American astronomer Heber D. Curtis in 1973. In the past it was designated Picard Z.

Yerkes (crater)

Yerkes is a lunar impact crater near the western edge of Mare Crisium. It was named after American financier Charles Yerkes. To the east of Yerkes is the crater Picard, and farther to the north is Peirce.

Alhazen (crater)

Alhazen is a lunar impact crater that lies near the eastern limb of the Moon's near side. Just to the south-southeast is the crater Hansen, and to the west is the Mare Crisium. The rim of Alhazen is nearly circular, but appears highly oblong when viewed from the Earth due to foreshortening. The inner walls and the crater floor are rugged and irregular. A low ridge joins the south rim of Alhazen with the nearby Hansen. The crater is named after the Arab Muslim scientist, Ibn al-Haytham.

Greaves (crater) Lunar crater

Greaves is a small lunar impact crater that lies near the southwest edge of Mare Crisium. It is a circular, bowl-shaped formation with a small interior floor at the center of the sloping inner walls. The crater is intruding into the northern edge of the lava-flooded crater Lick. To the northwest is Yerkes, and to the northeast is Picard.

Condorcet (crater) Lunar impact crater

Condorcet is a lunar impact crater that is located in the eastern part of the Moon's near side, to the southeast of the Mare Crisium. It was named after French mathematician Marquis de Condorcet. To the northeast of Condorcet are the craters Hansen and Alhazen.

Shapley (crater)

Shapley is a lunar impact crater that lies along the southern edge of Mare Crisium. It was named after American astronomer Harlow Shapley. It was previously designated Picard H. However the crater Picard lies about 150 kilometers to the north-northwest across the Mare Crisium. Somewhat closer to this crater are Tebbutt to the west, and Firmicus to the east-southeast.

Glaisher (crater)

Glaisher is a lunar impact crater that is located in the region of terrain that forms the southwest border of Mare Crisium. It lies to the southwest of the lava-flooded crater Yerkes, and west-northwest of the Greaves–Lick crater pair. It is surrounded by a ring of satellite craters of various dimensions, the larger companions generally being arranged to the south of Glaisher.

Van Albada (crater)

van Albada is a lunar impact crater that is attached to the south-southeastern rim of Auzout. It lies southeast of Mare Crisium, and north-northeast of the larger crater Firmicus. Directly to the east is Krogh.

Firmicus (crater)

Firmicus is a lunar impact crater that lies in the eastern part of the Moon's near side, so that from Earth it appears oval in shape due to foreshortening. It is, however, very nearly circular. The crater is located to the west of the Mare Undarum, and northeast of the similar-sized crater Apollonius. To the north of Firmicus are the craters van Albada and Auzout. Attached to its northwest rim is the Lacus Perseverantiae, a miniature lunar mare.

Peirce (crater)

Peirce is a small lunar impact crater in the western part of Mare Crisium. That dark, circular lunar mare is located in the east-northeasterly part of the Moon's near side. It was named after the American mathematician Benjamin Peirce. Peirce lies to the north of the craters Yerkes and Picard, and southeast of Macrobius located outside the mare. Just over a crater diameter to the north of Peirce is the smaller Swift. To the northwest is the wrinkle ridge Dorsum Oppel.

Swift (lunar crater)

Swift is a small lunar impact crater that is located in the northwestern part of the Mare Crisium, in the northeast part of the Moon's near side. Within two crater diameters to the south is the larger crater Peirce. It was named after American astronomer Lewis A. Swift. Swift was previously designated Peirce B.

Fredholm (crater)

Fredholm is a small lunar impact crater that is located in the rugged ground to the west of the Mare Crisium. It was named after Swedish mathematician Erik I. Fredholm. It was previously designated Macrobius D. It lies midway between the prominent craters Macrobius to the north and Proclus almost due south.

Macrobius (crater)

Macrobius is a prominent lunar impact crater located to the northwest of the Mare Crisium. Its diameter is 63 km. It was named after ancient Roman writer Macrobius. It lies on the southeast edge of the Lacus Bonitatis, a small lunar mare. The somewhat smaller crater Tisserand lies just to the east.

Leibnitz (crater) Lunar impact crater

Leibnitz is a huge lunar impact crater that is located in the southern hemisphere on the far side of the Moon. This formation is the same size as Clavius on the near side. It is located to the east-southeast of Mare Ingenii, and is joined to the northeast rim of Von Kármán. Attached to the eastern rim of Leibnitz is Davisson, and intruding into the southeast rim is Finsen. Farther to the west is the large Oppenheimer.

Delmotte (crater)

Delmotte is a small lunar impact crater that lies just to the east of the much larger crater Cleomedes, and to the north of the Mare Crisium, in the northeastern part of the Moon. Delmotte appears foreshortened when viewed from the Earth, although not sufficiently to obscure the interior details.
