Banting is a small, bowl-shaped lunar impact crater located near the middle of the Mare Serenitatis on the Earth's moon.
Originally named Linné E, in 1973 the crater was renamed for Sir Frederick Banting [1] in honour of his outstanding medical contributions – the most famous being his discovery of insulin. [2] Linné itself, named after the 18th-century Swedish botanist Carl von Linné, lies to the west-northwest.
"Banting" was one of approximately fifty new names for lunar craters adopted by the International Astronomical Union in 1973. Choosing the names was the first step in the adoption of a new policy that involved broadening crater nomenclature.
The policy was created because of photographs taken by the Apollo spacecraft, which provided an extremely detailed and crater-populated lunar map, essentially proving that a greater variety of names would be needed. The practice that had previously been used was to name one large crater after a selected individual and to name the small craters around it with the same name followed by different letters of the alphabet.
The new policy allowed deceased scientists who had contributed to biological knowledge, like Dr. Banting – as well as scientists from other fields and contributors to culture and knowledge, such as writers, composers, and artists – to have craters named after them. Previously, only the names of astronomers, others who had made important contributions to astronomy, and historical philosophers had been used. [2] [3]
Banting is a 4-mile-wide (6.4 km) [2] "simple" impact crater. [4] It is located in the Sea of Serenity, which is also known as Mare Serenitatis, a large patch of lunar mare. Maria like Mare Serenitatis are dark, smooth areas created by lava pooling on the surface and then cooling, covering up any previously existing craters. They were originally called maria ("seas") because astronomers believed they were bodies of water. [5]
Banting is flanked by two U.S. lunar landing sites – those of Apollo 15 and 17 – which lie several hundred miles on either side of the crater. [2]
Mare Serenitatis is frequently perceived to be the eastern eye of the Man in the Moon. [6] [7] The Man in the Moon is on the near side of the Moon, which constantly faces Earth because of its tidally locked orbit. [8] This makes Sir Frederick's crater fairly central, since Mare Serenitatis is so easily viewed.
Despite its location, Banting is a very small crater and can be difficult to see. A telescope must be used, and viewing during certain lunar phases is crucial to seeing such small craters, as well. It is recommended that, while it is waxing, the moon be viewed around the time of its first quarter; while it is waning, it should be viewed just before its last quarter. Craters may also be conspicuous during a gibbous moon, when it is between quarter and full. These phases all provide just enough shadow to outline the details of the lunar surface without its being too dark, whereas the full moon is too bright, washing out all details. [9] [10]
Linné is a small lunar impact crater located in the western Mare Serenitatis. It was named after Swedish botanist Carl Linnaeus. The mare around this feature is virtually devoid of other features of interest. The nearest named crater is Banting to the east-southeast. The estimated age of this copernican crater is only a few tens of millions of years. It was earlier believed to have a bowl shape, but data from the LRO showed that it has a shape of a flattened, inverted cone. The crater is surrounded by a blanket of ejecta formed during the original impact. This ejecta has a relatively high albedo, making the feature appear bright.
Plinius is a prominent lunar impact crater on the border between Mare Serenitatis to the north and Mare Tranquilitatis to the south. Its diameter is 41 km. The crater is named after the Roman natural scientist and author Pliny the Elder. To the south-southeast of Plinius is the crater Ross, and to the northeast is Dawes. Just to the north is a system of rilles named the Rimae Plinius and touching it is the Brackett crater which is more than a crater diameter north. At the northwest edge of the rille is the Promontorium Archerusia, a cape off the western rim that encloses the Mare Serenitatis.
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.
Brackett is a small lunar impact crater that lies near the southeast edge of Mare Serenitatis. The crater is named after American physicist Frederick Sumner Brackett. The crater has been covered by lava flow, leaving only a ring-shaped trace in the surrounding lunar mare. This crater is best observed under oblique illumination, as it is otherwise difficult to find. The southern rim is almost contacting a rille system named the Rimae Plinius.
Posidonius is a lunar impact crater that is located on the north-eastern edge of Mare Serenitatis, to the south of Lacus Somniorum. It was named after ancient Greek philosopher and geographer Posidonius of Apamea. The crater Chacornac is attached to the southeast rim, and to the north is Daniell.
Abetti is a lunar impact crater that has been completely submerged by mare lavas. It forms a 'ghost crater' in the surface, showing only a curved rise where the rim is located. Abetti is located near the southeast edge of Mare Serenitatis, to the west of the Mons Argaeus. This crater is generally visible only at low angles of illumination. It is named after two Italian astronomers, Antonio Abetti and his son Giorgio.
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.
Borel is a tiny lunar impact crater located in the southeast part of Mare Serenitatis. It was named after French mathematician Émile Borel. To the northeast is the crater Le Monnier and to the southeast is the crater Abetti. Borel was previously identified as Le Monnier C.
Deseilligny is a small lunar impact crater in the southern part of the Mare Serenitatis. It was named after French selenographer Jules Deseilligny. It is located to the east-southeast of the crater Bessel. Deseilligny is a bowl-shaped crater with a low rim. It is otherwise undistinguished.
Finsch is a relatively small lunar impact crater in the mid-part of Mare Serenitatis that has been almost completely covered by the mare, forming a ghost crater in the lava plain. It was named after German zoologist Otto Finsch. It is located to the south-southeast of the crater Sarabhai and northeast of Bessel.
Al-Bakri is a small lunar impact crater on the northwest edge of Mare Tranquillitatis. It is named after the Spanish Arab geographer and historian Abu Abdullah al-Bakri. It is just south of the eastern arm of the Montes Haemus that borders the Mare Serenitatis to the north. To the east-northeast is the prominent crater Plinius. South of the crater are the rilles of the Rimae Maclear.
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.
Clerke is a tiny lunar impact crater named after Irish astronomer Agnes Mary Clerke, who played a role in bringing astronomy and astrophysics to the public in Victorian England. It is located near the eastern edge of Mare Serenitatis in the midst of a rille system named the Rimae Littrow after the crater Littrow to the east. It is roughly circular and cup-shaped, with a relatively high albedo. In a valley to the southeast is the landing site of the Apollo 17 mission. Clerke was previously designated Littrow B.
Sulpicius Gallus is a small, bowl-shaped lunar impact crater that lies near the southwestern edge of the Mare Serenitatis. The crater is named after the 2nd century BC Roman astronomer Gaius Sulpicius Gallus.
Auwers is a small lunar impact crater located in the Montes Haemus mountain range at the south edge of Mare Serenitatis. It is named after German astronomer Arthur Auwers. It lies southeast of the crater Menelaus. The irregular rim of Auwers has a gap at the north-northwest edge, which allowed lava flows to reach the crater floor and flood the interior.
Calippus is a small lunar impact crater that is located on the eastern edge of the rugged Montes Caucasus mountain range in the northern part of the Moon. It was named after Greek astronomer Callippus of Cyzicus. It lies to the southwest of the crater remnant Alexander, to the northwest of the Mare Serenitatis.
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.
Fabbroni is a small lunar impact crater that lies along the northern edge of the Mare Tranquillitatis, at the eastern edge of the gap where the lunar mare joins Mare Serenitatis to the north. To the southeast is the crater Vitruvius.
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.
