Dorsa Aldrovandi is a wrinkle ridge system at 23°36′N28°42′E / 23.6°N 28.7°E in Mare Serenitatis on the Moon. It is about 127 km long and was named after the 16th century Italian naturalist Ulisse Aldrovandi. [1] The north end of the feature is at the crater Le Monnier, and the south end is close to the craters Clerke and Abetti.
Southeast of the ridge is Catena Littrow. West of the southernmost part of the ridge are the crater Borel and the nearest other wrinkle ridge Dorsa Lister.
Mare Crisium is a lunar mare located in the Moon's Crisium basin, just northeast of Mare Tranquillitatis. The basin is of the Pre-Imbrian period, 4.55 to 3.85 billion years ago.
Mare Serenitatis is a lunar mare located to the east of Mare Imbrium on the Moon. Its diameter is 674 km (419 mi).
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.
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.
Sinus Iridum is a plain of basaltic lava that forms a northwestern extension to the Mare Imbrium on Earth's moon. It is surrounded from the northeast to the southwest by the Montes Jura range. The protruding part of the range at the southwest end is named Promontorium Heraclides, while that at the northeast end is called Promontorium Laplace. This bay and the surrounding mountains is considered one of the most beautiful features on the Moon, and is a favorite among lunar observers.
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 Lister is a wrinkle ridge system at 20.3°N 23.8°E on the Moon, in southern Mare Serenitatis. It is 180 km in diameter and was named after English naturalist and physician Martin Lister 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 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 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.
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.
Maggini is a large Martian impact crater in northwestern Arabia Terra, located in the Arabia quadrangle at 28.0° N and 350.6° W. It measures 143.0 kilometers in diameter and was named after Mentore Maggini. The name was approved by IAU's Working Group for Planetary System Nomenclature in 1973.
