Dorsa Cato is a wrinkle ridge at 1°00′N47°00′E / 1.0°N 47.0°E on the Moon. It is approximately 130 km long and was named after the ancient Roman senator and historian Cato the Elder in 1976 by the IAU. [1]
The dorsa are located north of the prominent Messier crater in Mare Fecunditatis.
Ångström is a small lunar impact crater located on the border between Oceanus Procellarum to the west and Mare Imbrium to the east. To the south is a formation of mountains rising out of the mare named the Montes Harbinger. To the east are some wrinkle ridges named the Dorsum Bucher and Dorsa Argand. This crater is bowl-shaped, with a circular rim and inner walls that slope down to the small central floor. It has a higher albedo than the surrounding maria. The crater halo is radar dark, indicating a lack of larger blocks among the fine ejecta.
Humason is a tiny lunar impact crater located in the Oceanus Procellarum. This is a cup-shaped crater with an outer rim that rises slightly above the surrounding lunar mare. To the west is a low system of mare wrinkle ridges named the Dorsa Whiston that wind southwards towards Montes Agricola.
Very is a small lunar impact crater located in the eastern part of Mare Serenitatis, to the west-southwest of Le Monnier. It lies upon a wrinkle ridge that runs to the north and south named Dorsa Smirnov. It was named after American astronomer Frank W. Very. The crater was previously known as Le Monnier B, a satellite crater of Le Monnier, before being renamed by the IAU in 1973.
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.
Cajal is a small lunar impact crater on the northern part of the Mare Tranquilitatis. It was named after the Spanish doctor and Nobel laureate Santiago Ramón y Cajal. It is a circular, cup-shaped formation that lies southeast of the lava-inundated crater Jansen. Cajal was formerly designated Jansen F. Also to the northwest is a system of wrinkle ridges designated the Dorsa Barlow.
Dorsa Andrusov is a wrinkle ridge system at 1.0°S 57.0°E in Mare Fecunditatis on the Moon. It is 160 km in diameter and was named after Soviet geologist Nicolai Ivanovich Andrusov in 1976 by the IAU.
Dorsa Argand is a wrinkle ridge system at 28.1°N 40.6°W on the Moon, in Oceanus Procellarum near the border with Mare Imbrium. It is approximately 92 km long and was named after Swiss geologist Émile Argand in 1976. The name of the feature was approved by the IAU in 1976.
Dorsa Barlow is a wrinkle ridge system on the Moon, in Mare Tranquilitatis near the border with Mare Serenitatis, centered at 14.0°N 30.6°E. It is about 110 km long and was named after British crystallographer William Barlow in 1976.
Dorsa Smirnov is a wrinkle ridge system at 27.3°N 25.3°E in eastern Mare Serenitatis on the Moon. It is 222 km long and was named after Soviet geologist Sergei Sergeevich Smirnov by the IAU in 1976.
Dorsa Burnet are wrinkle ridges at 28.4°N 57.0°W in Oceanus Procellarum on the Moon. They are about 194 km long and were named after Thomas Burnet by the IAU in 1976.
Dorsa Dana is a wrinkle ridge at 3.0°N 90.0°E in Mare Smythii on the Moon. It is 82 km long and was named after American geologist James Dwight Dana in 1976.
Dorsa Geikie is a wrinkle ridge at 4.6°S 52.5°E in Mare Fecunditatis on the Moon. It is approximately 220 km long and was named after Scottish geologist Sir Archibald Geikie in 1976 by the IAU.
Dorsa Harker is a wrinkle ridge at 14.5°N 64.0°E in Mare Crisium on the Moon. It is 213 km long and was named after Alfred Harker, an English petrologist, in 1976.
Dorsa Mawson is a wrinkle ridge system at 7.0°S 53.0°E in Mare Fecunditatis on the Moon. It is approximately 143 km long and was named after Antarctic explorer Douglas Mawson in 1979 by the IAU.
Dorsa Sorby is a wrinkle ridge system at 19.0°N 14.0°E in Mare Serenitatis on the Moon. It is 76 km long and was named after British geologist Henry Clifton Sorby in 1976.
Dorsa Stille is a wrinkle ridge system at 27.0°N 19.0°W in Mare Imbrium on the Moon. It is 66 km long and was named after German geologist Hans Stille in 1976.
Dorsum Cayeux is a wrinkle ridge at 1.6°N 51.2°E in Mare Fecunditatis on the Moon. It is approximately 95 km long and was named after French geologist Lucien Cayeux in 1976 by the IAU.
Dorsum Nicol is a wrinkle ridge on the Moon at 18.0°N 23.0°E in Mare Serenitatis near the border of Mare Tranquilitatis. It is 44 km long and was named after Scottish physicist William Nicol in 1976.
Rupes Cauchy is a 120 km-long escarpment at 9.0°N 37.0°E on the surface of the Moon. It faces southwest, and rises about 200–300 m. It is located in the northeastern portion of the Mare Tranquillitatis, and is named after the nearby crater Cauchy.
