Tolansky is a small, circular lunar impact crater that is located due south of the crater Parry on the Mare Cognitum. The formation is symmetric, with a light-hued outer rim and a darker interior floor. A rille belonging to the Rimae Parry almost connects with the north-northwestern rim of Tolansky.
Lunar craters are impact craters on Earth's Moon. The Moon's surface has many craters, almost all of which were formed by impacts.
An impact crater is an approximately circular depression in the surface of a planet, moon, or other solid body in the Solar System or elsewhere, formed by the hypervelocity impact of a smaller body. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Impact craters range from small, simple, bowl-shaped depressions to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth.
Parry is a lunar impact crater that is attached to the southeast rim of the walled plain Fra Mauro. It was named after British explorer William Parry. Attached to the west and southwest rim of Parry is the crater Bonpland. Due south of Parry is the small crater Tolansky, and farther to the south-southwest is Guericke.
It was named after British physicist Samuel Tolansky. [1] It was formerly known as Parry A, prior to its current name being approved by the IAU in 1976.
Samuel Tolansky born Turlausky, DThPT PhD (Dunelm) PhD (Lond) DSc (Manc) FRAS FRSA FInstP FRS He was nominated for a Nobel Prize, has a crater on the moon named after him near the Apollo 14 landing site and he was a principal investigator to the NASA lunar project known as the Apollo program.
The International Astronomical Union is an international association of professional astronomers, at the PhD level and beyond, active in professional research and education in astronomy. Among other activities, it acts as the internationally recognized authority for assigning designations and names to celestial bodies and any surface features on them.
Bohnenberger is a lunar impact crater that lies near the east edge of the Mare Nectaris, in the foothills of the Montes Pyrenaeus mountain range that forms the perimeter of the mare. To the east beyond the mountains is the larger crater Colombo. The crater has a low rim along the north wall, and the floor is somewhat irregular with a ridge crossing the floor. There is a small crater along the western inner wall.
Bonpland is the remains of a lunar impact crater that is attached to the walled plain Fra Mauro to the north and Parry to the east. The intersection of their rims forms a three-pointed mountainous rise. To the southeast is the small crater Tolansky. Bonpland lies on the eastern edge of Mare Cognitum. It is named after Aimé Bonpland, a French explorer and botanist.
Artamonov is a lunar impact crater that is located on the far side of the Moon. The eroded outer rim of Artamonov does not have the circular shape of most lunar craters, and instead has the overall shape of three or four merged craters. The largest of these formations is in the south, with smaller circular bulges to the north and east.
Atwood is a small lunar 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.
Beals is a lunar impact crater that is located near the eastern limb of the Moon, and lies across the southwestern rim of the crater Riemann. From the Earth the crater is viewed nearly from on edge, and is best seen during favorable librations. To the west is the large walled plain Gauss.
Fizeau is a prominent lunar impact crater that is located on the far side of the Moon, in the southern hemisphere. Nearby craters of note include Minkowski to the west-northwest, and Eijkman to the southwest.
Borda is a lunar impact crater that lies between Santbech to the north-northwest and Reichenbach slightly further away to the south-southeast. It was named after French astronomer Jean-Charles de Borda. It has a low rim that is broken along the southeast by a smaller crater. The rim is intruded into by another small crater along the southwest side, and there is an irregular cleft along the northwest face. There is a central peak at the midpoint of the floor.
Barringer is a lunar impact crater that is located on the southern hemisphere on the far side of the Moon. It is attached to the north-northeastern rim of the walled basin named Apollo, and lies to the southeast of Plummer. South of Barringer, on the floor of the Apollo basin, is the crater Scobee.
Bobone is an old, heavily eroded crater formation that lies on the far side of the Moon. Little remains of the original crater formation, leaving only a bowl-shaped depression in the surface that is pock-marked by tiny craterlets. It is attached to the southwest rim of the large satellite crater Kovalevskaya Q, which has its northeast rim overlaid by Kovalevskaya itself. To the west-southwest is Bronk.
Buisson is a lunar impact crater that is located on the far side of the Moon. It is named after the French physicist Henri Buisson. Nearly attached to the southeast rim is the crater Vesalius. To the southwest is Einthoven. The rim of this crater is somewhat worn, and is lowest in the north. There is a low central ridge across the midpoint.
Damoiseau is a lunar impact crater that is located just to the west of the Oceanus Procellarum, in the western part of the Moon's near side. It lies due east of the prominent crater Grimaldi, a walled plain with a distinctive dark floor. Due south of Damoiseau is the crater Sirsalis.
Einthoven is a lunar impact crater that is located on the far side of the Moon. It is located beyond the region of the surface that is sometimes brought into view due to libration, and so can not be viewed from the Earth. Einthoven is located to the northeast of the huge walled plain Pasteur.
Weierstrass is a small lunar impact crater that is attached to the northern rim of the walled plain Gilbert, in the eastern part of the Moon. It also lies very near the crater Van Vleck, a similar formation just to the southeast that is almost attached to the outer rim. Due to its location, the crater appears foreshortened as seen from the Earth.
Fleming is a large lunar impact crater that is located on the Moon's far side, and cannot be seen from the Earth. It lies about a crater diameter to the east-northeast of Hertz, and to the northwest of Lobachevskiy.
Florensky is a lunar impact crater that is attached to the northeastern rim of the larger crater Vernadskiy. It is located on the far side of the Moon and cannot be directly seen from the Earth. The rim of this crater has been heavily eroded and it forms an irregular ring about the uneven interior. This crater was previously identified as Vernadskiy B before being assigned a name by the IAU in 1985.
Garavito is a lunar impact crater that is located in the southern hemisphere on the Moon's far side. It lies to the north-northwest of the huge walled plain Poincaré, and to the west of the crater Chrétien. It takes its name in honor of the Colombian astronomer and engineer Julio Garavito Armero.
Lomonosov is a lunar impact crater that is located just behind the western limb of the Moon. It is almost attached to the east-northeastern outer rim of the larger crater Joliot, and overlies the southern rim of Maxwell. Attached to the southern rim of Lomonosov is the smaller Edison.
Möbius is a lunar impact crater that is located on the Moon's far side, beyond the eastern limb and northeast of the Mare Marginis. It lies less than one crater diameter to the northwest of the larger, 90-km-diameter Hertz, and just to the southeast of Popov. To the north of Mobius is the crater chain designated Catena Dziewulski, which takes its name from the crater Dziewulski to the north-northwest.
Schuster is a lunar impact crater that lies along the eastern rim of the much larger walled plain Mendeleev, on the far side of the Moon. To the east of Schuster is the crater Henderson, and to the southeast lies the large Chaplygin.
Ewen Adair Whitaker was a British-born astronomer who specialized in lunar studies. During World War II he was engaged in quality control for the lead sheathing of hollow cables strung under the English Channel as part of the "Pipe Line Under The Ocean" Project (PLUTO) to supply gasoline to Allied military vehicles in France. After the war, he obtained a position at the Royal Greenwich Observatory working on the UV spectra of stars, but became interested in lunar studies. As a sideline, Whitaker drew and published the first accurate chart of the South Polar area of the Moon in 1954, and served as director of the Lunar Section of the British Astronomical Association.
