Canso is a Martian crater. It lies about 450 kilometres west of the Viking 1 lander, slightly northeast of Lunae Planum, and west of Chryse Planitia, in the Lunae Palus quadrangle. The crater is named after Canso, a fishing town in Nova Scotia. The name was officially adopted in 1988 by the International Astronomical Union's Working Group for Planetary System Nomenclature (IAU/WGPSN).
Kepler is a crater on Mars, located in the Eridania quadrangle at 46.8° S, 140.9° E. It measures approximately 228 kilometres and was named in 1973, by the International Astronomical Union, in honor of the astronomer Johannes Kepler. A section of the floor of Kepler was photographed by the HiRISE camera aboard the Mars Reconnaissance Orbiter on 25 March 2006.
The Hokusai quadrangle (H-5) is one of fifteen quadrangles on the planet Mercury. It runs from 360 to 270° longitude and 20 to 70° latitude. Named after the Hokusai crater, it was mapped in detail for the first time after MESSENGER entered orbit around Mercury in 2011. It had not been mapped prior to that point because it was one of the six quadrangles that wasn't illuminated when Mariner 10 made its flybys in 1974 and 1975. These six quadrangles continued to be known by their albedo feature names, with this one known as the Apollonia quadrangle.
The Raditladi quadrangle (H-4) is one of fifteen quadrangles on Mercury. It runs from 270 to 180° longitude and 20 to 70° latitude. Named after the Raditladi Basin, it was mapped in detail for the first time after MESSENGER entered orbit around Mercury in 2011. It had not been mapped prior to that point because it was one of the six quadrangles that was not illuminated when Mariner 10 made its flybys in 1974 and 1975. These six quadrangles continued to be known by their albedo feature names, with this one known as the Liguria quadrangle.
The Eminescu quadrangle (H-9) is one of fifteen quadrangles on Mercury. It runs from 216 to 288° longitude and from -25 to 25° latitude. Named after the Eminescu crater, it was mapped in detail for the first time after MESSENGER entered orbit around Mercury in 2011. It had not been mapped prior to that point because it was one of the six quadrangles that was not illuminated when Mariner 10 made its flybys in 1974 and 1975. These six quadrangles continued to be known by their albedo feature names, with this one known as the Solitudo Criophori quadrangle.
The Debussy quadrangle (H-14) is one of fifteen quadrangles on Mercury. It runs from 270 to 360° longitude and from -20 to -70° latitude. Named after the Debussy crater, it was mapped in detail for the first time after MESSENGER entered orbit around Mercury in 2011. It had not been mapped prior to that point because it was one of the six quadrangles that was not illuminated when Mariner 10 made its flybys in 1974 and 1975. These six quadrangles continued to be known by their albedo feature names, with this one known as the Cyllene quadrangle.
The Ulysses Fossae are a group of troughs in the Tharsis quadrangle of Mars at 10.06° north latitude and 123.07° west longitude. They were named after an albedo feature name. The area contains pitted cones called Ulysses Colles which were interpreted to be possible Martian equivalents to terrestrial cinder cones.
Tyrrhenus Mons, formerly Tyrrhena Mons or Tyrrhena Patera, is a large volcano in the Mare Tyrrhenum quadrangle of Mars, located at 21.36° south latitude and 253.47° west longitude. The name "Tyrrhena Patera" now refers only to the central depression, a volcanic crater or caldera. It was named after a classical albedo feature name. Pit chains are found at the summit of Tyrrhenus Mons. They are formed by collapse of material into underground voids. Since they form chains and concentric fractures that are aligned, they are probably caused by extension of the surface. Volcanic processes made the crust pull apart. Voids were formed, then material fell into them, leaving holes. It is one of the oldest volcanoes on Mars. As a consequence of its old age, Tyrrhenus Mons has many radiating gullies on its slope. When it was formed, magma may have gone through frozen ground and then erupted as easily eroded ash, instead of lava flows.
Orson Welles is an impact crater in the Coprates quadrangle of Mars, located at 0.2° S and 45.9° W. It is 124.5 kilometers in diameter and was named after Orson Welles (1915–1985), an American radio and motion picture actor and director. He is famous for, among other things, his radio broadcast of The War of the Worlds by H. G. Wells in which Martians invade Earth. The layers and the clay minerals found in Orson Welles Crater are evidence that it once contained a lake.
Thila is an impact crater on Mars, located in the Elysium quadrangle at 18.09° N and 204.58° W. It measures approximately 5.37 kilometres (3.34 mi) in diameter and was named after the village of Thila in Yemen.
Persbo is an impact crater in the Elysium quadrangle of Mars. It measures 19.5 kilometer in diameter and was named after Persbo, Sweden. It is just south of the Cerberus Fossae, and is adjacent to the Athabasca Valles, which issue from one of the fossae. Impact craters generally have a rim with ejecta around them, in contrast volcanic craters usually do not have a rim or ejecta deposits. As craters get larger they usually have a central peak. The peak is caused by a rebound of the crater floor following the impact.
Arsia Chasmata is a steep-sided depression located northeast of Arsia Mons in the Phoenicis Lacus quadrangle on Mars, located at 7.6° S and 119.3° W. It is 97 km long and was named after an albedo name.
Maunder is an old, eroded crater on Mars, located in the Noachis quadrangle at 50 South and 358.5 West. It measures 91 kilometers in diameter and was named after British astronomer Walter Maunder in 1973.
Timbuktu is an old crater on Mars, located in the Margaritifer Sinus quadrangle (MC-19) region at 5.7° S and 37.6° W. It measures approximately 65.68 kilometres (40.81 mi) in diameter and was named after the ancient city of Timbuktu in Mali, Africa. The crater has numerous cracks that form an irregular figure similar to the streets found in Timbuktu.
Maraldi Crater is an impact crater in the Argyre quadrangle on Mars at 62.2°S and 32.0°W and is 124.0 km in diameter. Its name refers to French astronomer Giacomo F. Maraldi.
Skadi Mons is a mountain on Venus in Maxwell Montes, at the center of Ishtar Terra. It is the highest point of the planet with an altitude of about 10,700 meters above the mean planetary radius.
Baltisk is a crater in the Argyre quadrangle of Mars. It was named after a town in Russia in 1976. Baltisk is located on the western edge of the Argyre impact basin.
The Quadrangle of Henie is one of the 62 quadrilateral defined by the cartography of Venus approved by the International Astronomical Union.
