Mare Tranquillitatis is a lunar mare that sits within the Tranquillitatis basin on the Moon. It is the first location on another celestial body to be visited by humans.
In planetary nomenclature, a fossa is a long, narrow depression (trough) on the surface of an extraterrestrial body, such as a planet or moon. The term, which means "ditch" or "trench" in Latin, is not a geological term as such but a descriptor term used by the United States Geological Survey (USGS) and the International Astronomical Union (IAU) for topographic features whose geology or geomorphology is uncertain due to lack of data or knowledge of the exact processes that formed them. Fossae are believed to be the result of a number of geological processes, such as faulting or subsidence. Many fossae on Mars are probably graben.
Degas is a rayed crater on Mercury at latitude 37.5 N, longitude 127 W. Its diameter is 54 kilometres (34 mi). It was named after the French impressionist painter Edgar Degas in 1979. The rays consist of light colored material blasted out during the crater's formation. Craters older than Degas are covered by the ray material, while younger craters are seen superimposed on the rays. Degas forms a crater pair with Brontë to the north. Both lie near the center of Sobkou Planitia.
Cerberus is a large "dark spot" located on Mars and named after the mythical dog Cerberus. The arcuate (curved) markings in the upper right are in the Amazonis plains and may be sand drifts. The volcano Elysium Mons, a yellow area north of Cerberus, has several channels radiating from its flanks. The three bright spots, upper left, are volcanoes partially veiled by thin clouds.
Cleopatra, initially called Cleopatra Patera, is an impact crater on Venus, in Maxwell Montes.
Tempe Terra is a heavily cratered highland region in the northern hemisphere of the planet Mars. Located at the northeastern edge of the Tharsis volcanic province, Tempe Terra is notable for its high degree of crustal fracturing and deformation. The region also contains many small shield volcanoes, lava flows, and other volcanic structures.
Lermontov is an impact crater on the planet Mercury. The crater is named after Mikhail Yuryevich Lermontov, a 19th-century Russian poet. The name was approved by the International Astronomical Union in 1976.
Tolstoj is a large, ancient impact crater on Mercury. It was named after Leo Tolstoy by the IAU in 1976. The albedo feature Solitudo Maiae appears to be associated with this crater.
Michelangelo is a 230 km diameter impact basin in the Michelangelo quadrangle of Mercury, which is named after this crater. The crater itself was named by the IAU in 1979 after the Italian painter, sculptor and architect Michelangelo.
The Casius quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The quadrangle is located in the north-central portion of Mars’ eastern hemisphere and covers 60° to 120° east longitude and 30° to 65° north latitude. The quadrangle uses a Lambert conformal conic projection at a nominal scale of 1:5,000,000 (1:5M). The Casius quadrangle is also referred to as MC-6. Casius quadrangle contains part of Utopia Planitia and a small part of Terra Sabaea. The southern and northern borders of the Casius quadrangle are approximately 3,065 km and 1,500 km wide, respectively. The north to south distance is about 2,050 km. The quadrangle covers an approximate area of 4.9 million square km, or a little over 3% of Mars’ surface area.
Calvino is a crater on Mercury. Its name was adopted by the IAU in 2016, after the Italian writer Italo Calvino.
Hals is a crater on Mercury. It has a diameter of 93 kilometers. Its name was adopted by the International Astronomical Union (IAU) in 1985. Hals is named for the Dutch painter Frans Hals, who lived from 1581 to 1666.
Han Kan is a crater on Mercury. It has a diameter of 50 kilometers. Its name was adopted by the International Astronomical Union (IAU) in 1985. Han Kan is named for the Chinese painter Han Gan, who lived from 720 to 780.
Hawthorne is a crater on Mercury. It has a diameter of 120 kilometers. Its name was adopted by the International Astronomical Union in 1979. Hawthorne is named for the American novelist Nathaniel Hawthorne, who lived from 1804 to 1864.
Keats is a crater on Mercury. The crater's name was adopted by the International Astronomical Union (IAU) in 1976 and named after an English poet. This poet is known as John Keats, who lived from 1795 to 1821.
Kuan Han-Chʻing is a crater on Mercury. Its name was adopted by the International Astronomical Union in 1979. Kuan Han-Chʻing is named for the Chinese playwright Guan Hanqing, who lived from 1241 to 1320.
Nansen-Apollo is a feature on Earth's Moon, a crater in Taurus-Littrow valley, at the base of the South Massif. Astronauts Eugene Cernan and Harrison Schmitt visited it in 1972, on the Apollo 17 mission. The astronauts referred to it simply as Nansen during the mission. Geology Station 2 of the mission was located at Nansen. Nansen is located in the 'light mantle' which is almost certainly an avalanche deposit from the South Massif.
Belton Regio is a prominent surface feature of the dwarf planet Pluto. It is an elongated dark region along Pluto's equator, 2,990 km (1,860 mi) long and one of the darkest features on its surface.
Van Gogh is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) in 1976. Van Gogh is named for the Dutch painter Vincent van Gogh.
Rimbaud is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) in 1985. Rimbaud is named for French poet Arthur Rimbaud.
