A ray system comprises radial streaks of fine ejecta thrown out during the formation of an impact crater, looking somewhat like many thin spokes coming from the hub of a wheel. The rays may extend for lengths up to several times the diameter of their originating crater, and are often accompanied by small secondary craters formed by larger chunks of ejecta. Ray systems have been identified on the Moon, Earth, Mercury, and some moons of the outer planets. Originally it was thought that they existed only on planets or moons lacking an atmosphere, but more recently they have been identified on Mars in infrared images taken from orbit by 2001 Mars Odyssey's thermal imager.
Herschel is a 304 kilometer impact crater in the Martian southern hemisphere, at 14.5°S, 130°E, located in the Mare Tyrrhenum region of Mars. The crater is jointly named after the seventeenth/eighteenth century father and son astronomers William Herschel and John Herschel.
Oudemans is a crater on Mars, approximately 90 kilometers in diameter, named after Dutch astronomer Jean Abraham Chrétien Oudemans (1827–1906).
The Memnonia quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Memnonia quadrangle is also referred to as MC-16.
Kuiper is a moderate-size crater with a central peak cluster located at 11.35°S 31.23°W on Mercury. It is 62 kilometers in diameter and was named after Dutch-American astronomer Gerard Kuiper in 1976. It is one of only 2 Mercurian craters which are named not after artists, and one of very few cases when the same name is used for 3 craters. Gerard Kuiper, being a leader of American planetary science, died shortly before the first images of Mercurian surface were made.
Zunil is an impact crater near the Cerberus Fossae on Mars, with a diameter of 10.26 kilometres. It is named after the town of Zunil in Guatemala. The crater is located in the Elysium quadrangle. Visible in images from the Viking 1 and Viking 2 Mars orbiters in the 1970s, Zunil was subsequently imaged at higher resolution for the first time by the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) in 2000.
Cerulli is a crater in the Ismenius Lacus quadrangle on Mars with a diameter of 130 km. It lies in the northern hemisphere south of the very large crater Lyot. It is named after Vincenzo Cerulli, an Italian astronomer (1859–1927).
Proctor is a large crater in the Noachis quadrangle of Mars. It measures 168.2 kilometres in diameter and was named after Richard A. Proctor, a British astronomer (1837–1888).
Escalante Crater is an impact crater in the Amenthes quadrangle of Mars. It is located at 0.2° N and 244.7° W. It is 79.3 km (49.3 mi) in diameter, and was named after Mexican astronomer Francisco Javier Escalante Plancarte.
Puńsk is an impact crater on Mars, located in the Oxia Palus quadrangle at 20.8° N and 41.2° W. It measures 11.6 kilometers in diameter and was named after the village of Puńsk in Poland.
Zumba is a very young crater on Mars, located in the Phoenicis Lacus quadrangle at 28.68 South and 133.18 West. It measures approximately 2.93 kilometres (1.82 mi) in diameter and was named after the town of Zumba in Ecuador. The name was adopted by IAU's Working Group for Planetary System Nomenclature in 2006.
Dilly is a crater in the Elysium quadrangle of Mars, located at 13.24° North and 202.9° West. It is only 1.3 km in diameter and was named after Dilly, a town in Mali.
Hodgkins is a crater on Mercury. It has a diameter of 19 kilometers. Its name was adopted by the International Astronomical Union in 2009. Hodgkins is named for the New Zealand painter Frances Hodgkins, who lived from 1869 to 1947.
Balanchine is a crater on the planet Mercury. It possesses a ray system of slightly bluish rays. These rays inspired the name of the crater due to their similarity to the tutu in George Balanchine's Serenade.
Gasa is an impact rayed crater in the Eridania quadrangle on Mars at 35.68° S and 230.72° W. and is 6.5 km in diameter. Its name was approved in 2009, and it was named after a place in Bhutan. Gullies are evident in the images. It is now believed that the impact that created Gasa happened in a larger crater whose floor was covered with debris-covered glaciers. The larger crater is known as Cilaos, it is located at 35.71° S and 230.52° W. and is 21.4 km in diameter. Its name was approved on 15 August 2016, and it was named after a place in the island of Réunion.
Sinton is a crater in the Ismenius Lacus quadrangle on Mars. Sinton crater lies in the northern hemisphere, south of the very large crater Lyot and west of Ismeniae Fossae. It was named after Harvard astronomer William M. Sinton. The name was approved in 2007.
Perepelkin Crater is an impact crater in the Arcadia quadrangle of the planet Mars. It is located at 52.8°N latitude and 64.6°W longitude. It is 77 km in diameter. It was named after Russian astronomer Yevgeny Perepyolkin.
Crommelin is an impact crater in the Oxia Palus quadrangle of Mars, located at 5.1°N latitude and 10.2°W longitude. It is 113.9 km in diameter. It was named after British astronomer Andrew Crommelin (1865–1939), and the name was approved in 1973 by the International Astronomical Union (IAU) Working Group for Planetary System Nomenclature (WGPSN).
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.
