Dorsum Buckland is a large wrinkle ridge at 20°24′N12°48′E / 20.4°N 12.8°E in Mare Serenitatis on the Moon, 369 km long. It was named after British geologist William Buckland in 1976. [1]
Dorsum Buckland's ridges are 200 to 300 meters high and were formed by compressional stresses near the center of the basin, possibly over buried basin structures. [2]
Aryabhata, named after Indian astronomer Aryabhata, is the remnant of a lunar impact crater located in the eastern Mare Tranquillitatis. The crater has been almost submerged by lava-flow, and now only an arc-shaped ridge formed from the eastern half of the rim remains above the lunar mare. This crater was previously identified as Maskelyne E before being named by the IAU in 1979. Maskelyne itself is to the southwest.
Sampson is a relatively tiny lunar impact crater located near the central part of the Mare Imbrium. It was named after British astronomer Ralph Allan Sampson. To the northeast is the crater Landsteiner and to the southeast lies Timocharis. East of this crater is the Dorsum Grabau, a wrinkle ridge in the mare.
Bobillier is a tiny, cup-shaped lunar impact crater in the southwest part of Mare Serenitatis. It was named after French geometer Étienne Bobillier in 1976. It lies to the north-northwest of the crater Bessel. To the south and west is a wrinkle ridge designated Dorsum Buckland. Bobillier was previously identified as Bessel E.
Aratus is a small lunar impact crater located on the highland to the south and east of the rugged Montes Apenninus range. It is a circular, cup-shaped crater with a relatively high albedo. It was named after Greek astronomer Aratus of Soli. To the east is the Mare Serenitatis, and to the southwest is the somewhat larger crater Conon. North-northeast of Aratus is the landing site of the Apollo 15 mission, just beyond Mons Hadley Delta.
Cauchy is a small lunar impact crater on the eastern Mare Tranquillitatis. It was named after French mathematician Augustin-Louis Cauchy. It is circular and symmetric, with a small interior floor at the midpoint of the sloping inner walls. Due to the high albedo of this bowl-shaped formation, it is particularly prominent at full Moon.
Atwood is a small earth moon impact crater that is located on the Mare Fecunditatis, to the northwest of the prominent crater Langrenus. It forms a triple-crater formation with Naonobu attached to the north rim and Bilharz near the west rim.
Sarabhai is a small, circular, bowl-shaped crater on the Mare Serenitatis, in the northeast quadrant of the Moon. The formation is relatively isolated, being located to the northeast of the crater Bessel. It lies along a wrinkle ridge designated the Dorsum Azara.
Lyell is a lunar impact crater that lies along the eastern edge of the Mare Tranquillitatis, at the northern arm of the bay designated Sinus Concordiae. It was named after Scottish geologist Charles Lyell. To the north along the edge of the lunar mare is the crater Franz. The region of terrain to the east of Lyell is named Palus Somni.
Gilbert is a large lunar impact crater that lies near the eastern limb of the Moon. Due to its location this feature appears foreshortened when viewed from the Earth, limiting the amount of detail that can be observed. The crater lies to the northwest of the similar-sized walled plain Kästner, to the west of the Mare Smythii.
Daubrée is a lunar impact crater that is located to the southwest of the Mare Serenitatis, just to the west-southwest of the crater Menelaus in the Montes Haemus range. The small lunar mare Lacus Hiemalis lies along the southwest rim of Daubrée. The crater was named after French geologist Gabriel A. Daubrée. It was previously designated Menelaus S.
Hornsby is a tiny lunar impact crater in the western part of the Mare Serenitatis, a lunar mare in the northeast quadrant of the Moon's near side. It was named after British astronomer Thomas Hornsby. It is a solitary formation that is located at least 100 kilometers from any significant craters, although the curiously shaped depression Aratus CA lies about 50 km to the west-northwest. To the north-northwest is Linné, a feature notable for its skirt of high-albedo material. To the west of Hornsby is the wrinkle ridge Dorsum Von Cotta.
Fermi is a large lunar impact crater of the category named a walled plain. It was named after Italian-American physicist and Nobel laureate Enrico Fermi. It lies on the far side of the Moon and can not be viewed from the Earth. Thus this feature must be viewed from an orbiting spacecraft.
Kästner is a lunar impact crater that is located near the eastern limb of the Moon, to the southwest of the Mare Smythii. Just to the northwest of Kästner is the walled plain Gilbert. To the south is the prominent crater Ansgarius, and to the southwest lies La Pérouse.
Delporte is a lunar impact crater on the far side of the Moon. It overlies part of the northwestern rim of the huge walled plain Fermi, and the crater Litke is nearly attached to the southeastern rim.
Neujmin is a lunar impact crater on the Moon's far side. It is nearly attached to the west-southwest of the smaller crater Waterman, and lies to the southwest of the prominent Tsiolkovskiy.
Langemak is a prominent impact crater on the far side of the Moon. It is located less than one crater diameter west-northwest of Danjon, and nearly due east of Meitner. To the southwest of Langemak is Kondratyuk. Langemak partly overlies the larger and older crater Langemak N. This feature is also attached to the northeastern rim of Kondratyuk.
Dorsum Azara is a wrinkle ridge at 26.7°N 19.2°E in Mare Serenitatis on the Moon. It is 103 km long and was named after Spanish naturalist Félix de Azara in 1976.
Dorsum Gast is a wrinkle ridge at 24.0°N 9.0°E in Mare Serenitatis on the Moon. It is 65 km long and was named after American geochemist and geologist Paul Werner Gast in 1973.
Dorsum Von Cotta is a wrinkle ridge at 23.2°N 11.9°E in Mare Serenitatis on the Moon. It is 183 km long and trends south to north at approximately the lunar 12th parallel. It was named after German geologist Bernhard von Cotta in 1976.
Mons Argaeus is a mountainous massif on the Moon that extends for a length of 65 km towards the southeast. It is located at coordinates 19.33°N 29.01°E, wedging between Mare Serenitatis and Mare Tranquillitatis on their eastern border. The summit is approximately 2560 m above the plain of Mare Serenitatis to the west.
