Dorsa Burnet are wrinkle ridges at 28°24′N57°00′W / 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. [1]
The dorsa draw near the southwest end of the Montes Agricola, and curve around the western Aristarchus plateau. The craters Schiaparelli, Golgi, and Zinner lie to the west.
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.
Zinner is a tiny lunar impact crater located due north of the crater Schiaparelli on the Oceanus Procellarum. It is circular and cup-shaped, with a high albedo in comparison to the surrounding lunar mare. The crater has essentially no rim because the mare lava nearly flooded it. A ray from the crater Glushko crosses Zinner. To the northwest is the slightly larger crater Golgi. East of Zinner is the Dorsa Burnet wrinkle ridge system.
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.
A wrinkle ridge is a type of feature commonly found on lunar maria, or basalt plains. These features are low, sinuous ridges formed on the mare surface that can extend for up to several hundred kilometers. Wrinkle ridges are tectonic features created after the lava cooled and solidified. They frequently outline ring structures buried within the mare, follow circular patterns outlining the mare, or intersect protruding peaks. They are sometimes called veins due to their resemblance to the veins that protrude from beneath the skin.
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.
Letronne is the lava-flooded remnant of a lunar impact crater. It was named after French archaeologist Jean-Antoine Letronne. The northern part of the rim is completely missing, and opens into the Oceanus Procellarum, forming a bay along the southwestern shore. The formation is located to the northwest of the large crater Gassendi.To the west-southwest is the flooded crater Billy, and north-northwest lies the smaller Flamsteed.
Webb is a small lunar impact crater that is located near the eastern edge of the Mare Fecunditatis, in the eastern part of the Moon near the equator. It was named after British astronomer Thomas William Webb. It is to the north of the prominent crater Langrenus, and west of Maclaurin.
Mons Hadley is a massif in the northern portion of the Montes Apenninus, a range in the northern hemisphere of the Moon. It has a height of 4.5 km (2.8 mi) 14,764 ft (4,500 m) above the adjacent plain and a maximum diameter of 25 km at the base.
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 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 Cato is a wrinkle ridge at 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.
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 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.
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.
