A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon. When the original object enters the atmosphere, various factors such as friction, pressure, and chemical interactions with the atmospheric gases cause it to heat up and radiate energy. It then becomes a meteor and forms a fireball, also known as a shooting star; astronomers call the brightest examples "bolides". Once it settles on the larger body's surface, the meteor becomes a meteorite. Meteorites vary greatly in size. For geologists, a bolide is a meteorite large enough to create an impact crater.
Meteor Crater or Barringer Crater is an impact crater about 37 mi (60 km) east of Flagstaff and 18 mi (29 km) west of Winslow in the desert of northern Arizona, United States. The site had several earlier names, and fragments of the meteorite are officially called the Canyon Diablo Meteorite, after the adjacent Canyon Diablo.
Ilyinets is an impact crater in Ukraine.
The Cape York meteorite, also known as the Innaanganeq meteorite, is one of the largest known iron meteorites, classified as a medium octahedrite in chemical group IIIAB. In addition to many small fragments, at least eight large fragments with a total mass of 58 tonnes have been recovered, the largest weighing 31 tonnes. The meteorite is named after the location where the largest fragment was found: 23 miles (37 km) east of Cape York, in Savissivik, Meteorite Island, Greenland.
Ataxites are a structural class of iron meteorites with a high nickel content and show no Widmanstätten patterns upon etching.
Mesosiderites are a class of stony–iron meteorites consisting of about equal parts of metallic nickel-iron and silicate. They are breccias with an irregular texture; silicates and metal occur often in lumps or pebbles as well as in fine-grained intergrowths. The silicate part contains olivine, pyroxenes, and Ca-rich feldspar and is similar in composition to eucrites and diogenites.
A meteor air burst is a type of air burst in which a meteoroid explodes after entering a planetary body's atmosphere. This fate leads them to be called fireballs or bolides, with the brightest air bursts known as superbolides. Such meteoroids were originally asteroids and comets of a few to several tens of meters in diameter. This separates them from the much smaller and far more common "shooting stars", that usually burn up quickly upon atmospheric entry.
The Appley Bridge meteorite is a meteorite that hit ground at Halliwell Farm in Appley Bridge, Lancashire, England at around 8:45 PM on Tuesday, 13 October 1914.
Chambord is an iron meteorite found in Quebec.
Tademaït is a natural region in the Sahara Desert right in the centre of Algeria. It is located north of In Salah and south of the Grand Erg Occidental in the Adrar District of Adrar Province, El Ménia District of Ghardaïa Province and the northern end of Tamanrasset Province. It is one of the places of the Sahara Desert where the summer heat is most extreme.
Zagami is the largest single Martian meteorite ever found, weighing about 18 kilograms (40 lb). It landed 10 feet (3.0 m) from a farmer near Zagami, Nigeria, and became buried in a hole about 2 feet (0.61 m) deep. According to Ron Baalke of NASA/JPL, "The Zagami meteorite is the most easily obtainable SNC meteorite available to collectors," referring to the SNC classification of meteorites, of which Martian meteorites belong.
Bunburra Rockhole is an anomalous basaltic achondritic meteorite. Originally classified as a eucrite, it was thought to belong to a group of meteorites that originated from the asteroid 4 Vesta, but has since been reclassified based on oxygen and chromium isotopic compositions. It was observed to fall on July 21, 2007, 04:43:56 local time, by the Desert Fireball Network (DFN). Two fragments weighing 150g and 174g were recovered by the DFN at 31°21.0′S, 129°11.4′E in the Nullarbor Desert region, South Australia in November of the same year. This is the first meteorite to be recovered using the Desert Fireball Network observatory.
Mason Gully is an ordinary chondrite of subclass H5, and is the second meteorite to be recovered using the Desert Fireball Network (DFN) camera observatory. One stone weighing 24.5g was observed to fall by the Desert Fireball Network observatory in Western Australia on 13 April 2010 at 10h36m10s UTC. It was recovered by the DFN on 3 November 2010 by Dr. R. Merle and the Fireball network recovery team, and was found 150m from its predicted fall location based upon the observed trajectory and calculated mass.
Murrilli (Moo-da-lee) is an ordinary chondrite of subclass type H5. It is the third meteorite to be recovered using the Australia Desert Fireball Network (DFN) camera observatory. It was observed to fall on 27 November 2015 at 9:15pm local time in South Australia, and recovered by the DFN team on 31 December 2015 from Lake Eyre. As this region is a salt lake, the 1.68 kg rock punched a hole through the ground and was found 0.43 m below the surface. It was recovered 218m from the predicted fall line location.
Dingle Dell is a 1.15 kg ordinary chondrite of subclass L/LL5, and the fourth meteorite to be recovered by the Desert Fireball Network camera observatory. It fell in the Morawa region of Western Australia on 31 October 2016 8:05 pm local time, and was recovered less than a week later, on the morning of 7 November, in a paddock at Dingle Dell farm. Given the rapid turnaround for meteorite recovery and a lack of rainfall between fall date and find date, the rock is in pristine condition and shows no evidence of terrestrial weathering (W0). This particular meteorite fall demonstrates the proficiency of the DFN as a sample recovery tool for meteoritics.
Dimmitt is a meteorite that fell in prehistoric times in The United States. It was named after the nearest town of Dimmitt, Texas.
Tagounite is a rural Moroccan commune in the Zagora Province, Drâa-Tafilalet, Morocco, with about 17,412 inhabitants as of the 2004 census.
The El Ali meteorite (Arabic) or Ceel Cali (Somali), literally meaning, "Ali's Well," is a 15,150-kilogram (16.70-short-ton) meteorite that was known to the local population in Somalia for generations, but first only officially recognized as a meteorite in 2020.
