Ostwald is a lunar impact crater on the far side of the Moon. It lies just to the east of the crater Guyot, and near the northern border of Ibn Firnas. Recht lies along its eastern rim.

Contents

This is a worn and eroded crater formation with an irregular rim and inner wall due to multiple small impacts. A brief crater chain forms a cleft in the western inner face. The interior is somewhat more level, but is pock-marked by a multitude of tiny craterlets. There are some low central ridges to the south and northeast of the midpoint.

Naming

The crater is named after German chemist and Nobel laureate Wilhelm Ostwald. Prior to naming in 1970 by the IAU, [1] this crater was known as Crater 212. [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 Ostwald.

Bianchini (lunar crater)

Bianchini is a lunar impact crater that lies along the northern Jura Mountains that ring the Sinus Iridum, in the northwestern part of the near side of the Moon. It was named after Italian astronomer Francesco Bianchini. The impact of this crater near the edge of the Jura Mountains deposited some material into the Sinus Iridum floor.

Beals (crater) Lunar impact crater

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 (crater) Lunar impact crater

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.

Cusanus (crater) Lunar crater

Cusanus is a lunar impact crater that is located near the northeastern limb of the Moon. In this location the crater appears very foreshortened when observed from the Earth, and its visibility is affected by libration. The northern rim of Cusanus is nearly joined to the south-southeastern rim of the larger crater Petermann. To the west is Baillaud and to the southeast is Hayn.

Casatus (crater) Lunar impact crater

Casatus is a lunar impact crater that is located near the southern limb of the Moon. The north-northeast rim of the crater overlies a portion of the slightly larger crater Klaproth. Along the western rim, Casatus A intrudes somewhat into the interior, producing an inward-bowing rim. To the southeast of Casatus is Newton.

Demonax (crater) Lunar impact crater

Demonax is a lunar impact crater near the southern limb of the Moon. This location makes the crater difficult to observe due to foreshortening. The crater is also illuminated at a very low angle, when it is in the sunlit side. Demonax lies just to the north of the crater Scott, one of the south polar formations. To the north-northwest is Boguslawsky.

Chrétien (crater) Lunar impact crater

Chrétien is a lunar impact crater that is located in the southern hemisphere on the far side of the Moon from the Earth. It lies due south of the Mare Ingenii, one of the few maria on the Moon's far side. The crater lies in the midpoint between the craters Garavito to the west-southwest and Oresme to the east-northeast, both of these being somewhat smaller than Chrétien.

Carver (crater) Lunar impact crater

Carver is a lunar impact crater that is located on the far side of the Moon, due east of the walled plain Van der Waals. To the northeast is the crater Rosseland, and to the south-southeast lies Kozyrev.

Dyson (crater) Lunar impact crater

Dyson is a lunar impact crater, 63 kilometers in diameter, that lies on the far side of the Moon, past the northwest limb. It is located in the northern part of the surface, to the northwest of the crater Coulomb, and east of van't Hoff.

Chandler (crater) Lunar impact crater

Chandler is a lunar impact crater in the northern hemisphere, on the Moon's far side. It lies to the southeast of the large walled plain D'Alembert, and southeast of the slightly smaller Chernyshev crater.

Chaplygin (crater) Lunar impact crater

Chaplygin is a large lunar impact crater that lies on the far side of the Moon. It is located to the southeast of the huge walled plain Mendeleev, about midway between the craters Schliemann to the northeast and Marconi to the southwest. It is about the same size as Albategnius on the near side.

Comstock (crater) Lunar impact crater

Comstock is a lunar impact crater that is located on the far side of the Moon. It lies to the northeast of the walled plain Fersman, and north of the crater Weyl.

Fourier (crater) Lunar impact crater

Fourier is a lunar impact crater that is located in the southwestern part of the Moon's near side, just to the southeast of the crater Vieta. To the northeast is the Mare Humorum. The rim of this crater is roughly circular, but appears oval when viewed from the Earth due to foreshortening.

Ibn Firnas (crater) Lunar impact crater

Ibn Firnas is a lunar impact crater on the far side of the Moon. In 1976 it was named after Abbas Ibn Firnas, a polymath from Andalucia who, in the 9th century, devised a chain of rings that could be used to simulate the motions of the planets and stars.

Guyot (crater)

Guyot is a lunar impact crater on the Moon's far side. It is separated from the crater Kostinskiy to the northeast by only a few kilometers of rough terrain. To the west-southwest lies the crater Lobachevskiy and to the east-southeast is Ostwald.

Harriot (crater) Lunar impact crater

Harriot is a lunar impact crater that is located on the far side of the Moon from the Earth. It lies just to the north of the much larger crater Seyfert. To the northeast of Harriot is the crater Cantor. About one and a half crater diameters to the north of Harriot is the eastern end of a crater chain named Catena Sumner. This feature continues to the west-northwest for a distance of 247 km, passing to the north of the crater Sumner.

Recht (crater)

Recht is a small impact crater on the far side of the Moon. It was named after the American mathematician and astronomer Albert William Recht. Is lies across the eastern rim of the much larger crater Ostwald. To the northeast of Recht is Meshcherskiy.

Meitner (lunar crater)

Meitner is an impact crater on the far side of the Moon, behind the eastern limb. It lies to the northwest of the crater Kondratyuk, and about a crater diameter to the west of Langemak.

Petropavlovskiy (crater)

Petropavlovsky is a crater on the far side of the Moon. It is attached to the southern rim of the slightly larger crater Razumov, intruding slightly into the interior. Just to the west is the crater Frost, along the southern rim of the walled plain Landau.

Papaleksi (crater)

Papaleksi is an impact crater on the far side of the Moon. It lies along the northeastern outskirts of the large crater Mandel'shtam. About 20 km to the north-northeast of Papaleksi is the similar crater Spencer Jones.
