List Of Craters With Ray Systems
This is a list of craters with ray systems. In the following tables, the listed coordinates and the diameter are for the crater. Mercury The following craters on Mercury possess ray systems. Mars The following craters on Mars possess ray systems (These were discovered in Thermal Emission Imaging System infrared images). Moon This table lists the lunar impact craters that have ray systems. Crater names followed by a letter are satellite craters associated with the primary crater of the same name. The list is not comprehensive because there are hundreds or thousands of small craters with ray systems that are not named. A few unnamed craters photographed during the Apollo program are included. See also * List of craters on the Moon This is a list of named lunar craters. The large majority of these features are impact craters. The crater nomenclature is governed by the International Astronomical Union, and this listing only includes features that are officially rec ...

Ray System
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 ( Kamil Crater), 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. Rays appear at visible, and in some cases infrared wavelengths, when ejecta are made of material with different reflectivity (i.e., albedo) or thermal properties from the surface on which they are deposited. Typically, visible rays have a higher albedo than the surrounding surface. More rarel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Degas (crater)
Degas is a rayed crater on Mercury at latitude 37.5 N, longitude 127 W. Its diameter is . 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. The crater's floor contains cracks that formed as the pool of impact melt Impact may refer to: * Impact (mechanics), a high force or shock (mechanics) over a short time period * Impact, Texas, a town in Taylor County, Texas, US Science and technology * Impact crater, a meteor crater caused by an impact event * Impac ... cooled and shrank.

Matabei (crater)
Matabei is an impact crater on Mercury. It has a set of dark rays. Dark rays are rare on Mercury, but other occurrences have been identified, such as at Mozart crater. Mozart crater is interpreted to have excavated dark material from depth during the impact event, creating dark streamers. The dark rays from Matabei may have a similar origin. Matabei was named by the IAU in 2009 after Japanese painter Iwasa Matabei. To the northeast of Matabei is the crater Pigalle. To the south is Rilke, and to the northwest is Guido d'Arezzo Guido of Arezzo ( it, Guido d'Arezzo; – after 1033) was an Italian music theorist and pedagogue of High medieval music.

Kulthum (crater)
Kulthum is a crater on Mercury. It has a diameter of 31 kilometers. Its name was suggested by Molouk Ba-Isa from Saudi Arabia, Swiss individual Riana Rakotoarimanana, and American residents Yehya Hassouna, David Suttles, Thorayya Said Giovannelli and Matt Giovannelli in a naming contest which was eventually adopted by the International Astronomical Union (IAU) on 2015. Kulthum is named for the Egyptian singer Umm Kulthum. Hollows are present as bright areas on the central peak of Kulthum.Zhiyong Xiao, Robert G. Strom, David T. Blewett, Paul K. Byrne, Sean C.

Kuiper (Mercurian Crater)
Kuiper is a moderate-size crater with a central peak cluster located at 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 (there are also Kuiper craters on Mars and on the Moon). Gerard Kuiper, being a leader of American planetary science, died shortly before the first images of Mercurian surface were made. Kuiper overlies the northern rim of the larger crater Murasaki. Kuiper crater has the highest recorded albedo of any region on the planet's surface and has a prominent ray system, suggesting that it is one of the youngest craters.Description Kuiper is one of the largest craters of the Kuiperian system on Mercury.

Hovnatanian (crater)
Hovnatanian is a crater on Mercury. Its “butterfly” pattern of ejecta rays were created by an impact at an even lower angle than that which formed neighboring Qi Baishi crater. From the "butterfly" pattern of rays (similar to Messier crater on the moon), the Hovnatanian impactor was travelling either north-to-south or south-to-north prior to hitting Mercury's surface. The crater was named for Hakob Hovnatanyan Hakob Hovnatanyan ( hy, Հակոբ Մկրտումի Հովնաթանյան; 1806–1881) was an Armenian artist. He was a member of the Hovnatanyan family, a miniaturists dynasty from the 17th to the 19th centuries. Hacob Hovantanyan who was als ..., a 19th-century Armenian artist.

Hokusai (crater)
Hokusai is a rayed impact crater on Mercury, which was discovered in 1991 by ground-based radar observations conducted at Goldstone Observatory. The crater was initially known as feature B. Its appearance was so dissimilar to other impact craters that it was once thought to be a shield volcano. However improved radar images by the Arecibo Observatory obtained later in 2000–2005 clearly showed that feature B is an impact crater with an extensive ray system. The bright appearance of rays in the radio images indicates that the crater is geologically young; fresh impact ejecta has a rough surface, which leads to strong scattering of radio waves. Hokusai is named after Katsushika Hokusai (1760–1849), a Japanese artist and printmaker of the Edo period The or is the period between 1603 and 1867 in the history of Japan, when Japan was under the rule of the Tokugawa shogunate and the country's 300 regional '' daimyo''.

Hodgkins (crater)
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 Frances Mary Hodgkins (28 April 1869 – 13 May 1947) was a New Zealand painter chiefly of landscape and still life, and for a short period was a designer of textiles. She was born and raised in New Zealand, but spent most of her working ..., who lived from 1869 to 1947. Hodgkins crater possesses a ray system and is thus a relatively recent impact.

Hitomaro (crater)
Hitomaro is a crater on Mercury. It has a diameter of 105 kilometers. Its name was adopted by the International Astronomical Union (IAU) in 1976. Hitomaro is named for the Japanese poet Kakinomoto no Hitomaro, who lived from the 650s to roughly 709. The impactor that created Hitomaro crater struck the west side of an older and larger peak ring basin (unnamed). The crater itself is unusual in that its central peak complex is offset to the west. It also possesses a ray system that has two dark lobes to the north and south, and lighter portions to the east and west. There are also hollows on the crater floor. Hitomaro is located west of the much larger Sanai crater. The crater Dvorák is to the northeast of Hitomaro. Balagtas, Kenkō, and Mahler Gustav Mahler (; 7 July 1860 – 18 May 1911) was an Austro-Bohemian Romantic composer, and one of the leading conductors of his generation.
