In astrogeology, an arachnoid is a large geological structure resembling a spider web. They are of unknown origin, and have been found only on the surface of the planet Venus. They appear as concentric ovals surrounded by a complex network of fractures, and can span 200 kilometers. Over 90 arachnoids have been identified on Venus.
Abeona Mons is a mountain on Venus named after Abeona the Roman goddess of travelers.
Addams is a crater on Venus. It was named after Jane Addams.
Merit Ptah is an impact crater on Venus, named in honor of alleged ancient Egyptian chief physician Merit Ptah whose existence was later exposed as a hoax.
Ciuacoatl Mons is a mountain on Venus. Its name is derived from the Aztec fertility goddess.
Artemis Corona is a corona found in the Aphrodite Terra continent, on the planet Venus, at 35°S135°E.
Beta Regio is a region of the planet Venus known as a volcanic rise. Measuring about 3,000 kilometres in extent, it constitutes a prominent upland region of Venus centered at 25.3°N 282.8°E.
A "quadrangle" is a topographic map produced by the United States Geological Survey (USGS) covering the United States. The maps are usually named after local physiographic features. The shorthand "quad" is also used, especially with the name of the map; for example, "the Ranger Creek, Texas quad". A quadrangle is defined by north and south boundaries of constant latitude, and by east and west boundaries of constant longitude.
Rupes is the Latin word for 'cliff'. It is used in planetary geology to refer to escarpments on other worlds. As of January 2013, the IAU has named 62 such features in the Solar System, on Mercury (17), Venus (7), the Moon (8), Mars (23), the asteroids Vesta (2) and Lutetia (2), and Uranus's satellites Miranda (2) and Titania (1).
Quetzalpetlatl Corona is a corona in Lada Terra on the planet Venus. Latitude 68° South, Longitude 357° East. It has a diameter of 780 kilometers, and is the 4th largest corona on Venus. It lies in part on the Lada Rise, with part of the corona intersecting the Ammavuro-Quetzalpetlatl belt in the northwestern region of Lada Terra.
Sobkou Planitia is a large basin on the planet Mercury. It is named after the ancient Egyptian messenger deity Sobkou. He was associated by the Egyptians with the planet Mercury.
Venus Glacier is a glacier on the east coast of Alexander Island, Antarctica, 10 nautical miles (18 km) long and 6 nautical miles (11 km) wide at its mouth flowing east into George VI Sound lying between Keystone Cliffs and Triton Point. The coast in this vicinity was first seen from the air by Lincoln Ellsworth on November 23, 1935 and roughly mapped from photos obtained on that flight by W.L.G. Joerg. The glacier was first surveyed in 1949 by the Falkland Islands Dependencies Survey and named by the United Kingdom Antarctic Place-Names Committee for the planet Venus, the second planet of the Solar System.
Irnini Mons is a volcanic structure on the planet Venus, and is named after the Assyro-Babylonian goddess of cedar-tree mountains. It has a diameter of 475 km (295 mi), a height of 1.75 km (1.09 mi), and is located in Venus' northern hemisphere. More specifically, it is located in the central Eistla Regio region at in the V-20 quadrangle. Sappho Patera, a 225 km (140 mi) diameter wide, caldera-like, depression tops the summit of Irnini Mons. The primary structural features surrounding Irnini Mons are graben, seen as linear depressed sections of rock, radiating from the central magma chamber. Also, concentric, circular ridges and graben outline the Sappho Patera depression at the summit. The volcano is crossed by various rift zones, including the north-south trending Badb Linea rift, the Guor Linea rift extending to the northwest, and the Virtus Linea rift continuing to the southeast.
Skadi Mons is a mountain on Venus in Maxwell Montes, at the center of Ishtar Terra. It is the highest point on the planet, with an altitude of about 10,700 meters above the mean planetary radius.
Aikhylu Chasma is a tectonic rift valley on Venus, and the landing site of the Venera 9 lander. It is located in Beta Regio.
