Meteorite Fall
A meteorite fall, also called an observed fall, is a meteorite collected after its fall from outer space was observed by people or automated devices. Any other meteorite is called a "find". There are more than 1,100 documented falls listed in widely used databases, most of which have specimens in modern collections. , the Meteoritical Bulletin Database had 1211 confirmed falls. Importance Observed meteorite falls are important for several reasons. Material from observed falls has not been subjected to terrestrial weathering, making the find a better candidate for scientific study. Historically, observed falls were the most compelling evidence supporting the extraterrestrial origin of meteorites. Furthermore, observed fall discoveries are a better representative sample of the types of meteorites which fall to Earth. For example, iron meteorites take much longer to weather and are easier to identify as unusual objects, as compared to other types. This may explain the increa ...

Bolide
A bolide is normally taken to mean an exceptionally bright meteor, but the term is subject to more than one definition, according to context. It may refer to any large crater-forming body, or to one that explodes in the atmosphere. It can be a synonym for a fireball, sometimes specific to those with an apparent magnitude of −14 or brighter. Definitions The word ''bolide'' (; from Italian via Latin, ) may refer to somewhat different phenomena depending on the context in which the word appears, and readers may need to make inferences to determine which meaning is intended in a particular publication. One sense refers to an extremely bright meteor, especially one that explodes in the atmosphere. In astronomy, it refers to a fireball about as bright as the full moon, and it is generally considered a synonym for a fireball. In geology, a bolide is a very large impactor. One definition describes a bolide as a fireball reaching an apparent magnitude of −14 or brightermore th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cape York Meteorite
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 tons have been recovered, the largest weighing . The meteorite is named after the location where the largest fragment was found: east of Cape York, in Savissivik, Meteorite Island, Greenland. The date of the meteorite fall is debated, but was likely within the last few thousand years. It was known to the Inughuit (the local Inuit) for centuries, who used it as a source of meteoritic iron for tools. The first foreigner to reach the meteorite was Robert Peary in 1894, with the assistance of Inuit guides. Large pieces are on display at the American Museum of Natural History and the University of Copenhagen Geological Museum. History The meteorite fell to Earth after the retreat of glaciers from the area. All fragments ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Campo Del Cielo
Campo del Cielo refers to a group of iron meteorites and the area in Argentina where they were found. The site straddles the provinces of Chaco and Santiago del Estero, located north-northwest of Buenos Aires, Argentina and approximately southwest of Asunción, Paraguay. The crater field covers and contains at least 26 craters, the largest being . The craters are estimated to be four to five thousand years old. They were reported to the general public in 1576, but were already well-known by aboriginal peoples. The craters and surrounding areas contain many fragments of an iron meteorite. In total, approximately 100 tonnes of fragments have been recovered, the most of any meteorite find. The two largest fragments, the 30.8-tonne '' Gancedo'' and 28.8-tonne ''El Chaco'', are among the heaviest single-piece meteorite masses recovered on Earth, following the 60-tonne Hoba meteorite and a 31-tonne fragment of the Cape York meteorite.

Gancedo (meteorite)
The Gancedo Meteorite is the largest known fragment of the meteor shower that fell in Campo del Cielo, in Charata, Chaco Province, Argentina. According to early reports, the meteorite weighs approximately , making it the largest meteorite found in the Americas and the third-largest in the world. Before 2016, El Chaco, also part of the Campo del Cielo meteorite fall, was estimated to be the largest fragment of this meteor shower. Its weight was estimated at but was re-estimated at in 2016. It makes Gancedo the third-largest worldwide, while Anighito, part of the massive Cape York meteorite fall found in Greenland, weighs . The largest single-piece find remains the Hoba meteorite, which was estimated at . Discovery The Gancedo meteorite was discovered underground on September 10, 2016 by a team of explorers from the Astronomy Association of the Chaco (''Asociación de Astronomía del Chaco''). The discovery site is several kilometers south of the town of Gancedo, in the sou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hoba Meteorite
The Hoba ( ) meteorite, short for Hoba West, is a meteorite that lies on the farm of the same name, not far from Grootfontein, in the Otjozondjupa Region of Namibia. It has been uncovered, but because of its large mass, has never been moved from where it fell. The main mass is estimated at more than 60 tonnes. It is the largest known intact meteorite (as a single piece) and about twice as massive as the largest fragment of either the Cape York meteorite's 31-tonne Ahnighito kept in Manhattan or the Campo del Cielo's 31-tonne Gancedo in Argentina. It is also the most massive naturally occurring piece of iron (actually ferronickel) known on Earth's surface. The name "Hoba" comes from a Khoekhoegowab word meaning "gift". Following donation to the government in 1987, a visitor centre was constructed with a circular stone access and seating area. Impact The Hoba meteorite impact is thought to have occurred less than 80,000 years ago. It is inferred that the Earth's atmosphere slowed ...

Meteorite Find
A meteorite find is a meteorite that was found by people, but whose fall was not observed. They may have been on Earth's surface for as many as thousands of years and therefore could have been subject to varying amounts of weathering. Finds are distinguished from " meteorite falls", which are those which were observed during their descent and collected shortly afterwards. All officially recognized meteorites are listed in databases such as the Meteoritical Bulletin Database, most of which have specimens in modern collections.

Chelyabinsk Meteorite
The Chelyabinsk meteorite (Russian: Челябинский метеорит, ''Chelyabinskii meteorit'') is the fragmented remains of the large Chelyabinsk meteor of 15 February 2013 which reached the ground after the meteor's passage through the atmosphere. The descent of the meteor, visible as a brilliant superbolide in the morning sky, caused a series of shock waves that shattered windows, damaged approximately 7,200 buildings and left 1,500 people injured. The resulting fragments were scattered over a wide area. The largest fragment raised from the bottom of Lake Chebarkul on 16 October 2013 had a mass of and the total mass of other 7 meteorite fragments found nearby was . Naming The meteor and meteorite are named after Chelyabinsk Oblast, over which the meteor exploded. An initial proposal was to name the meteorite after Lake Chebarkul, where one of its major fragments impacted and made a 6-metre-wide hole in the frozen lake surface. Composition and classificati ...

Metric Ton
The tonne ( or ; symbol: t) is a unit of mass equal to 1000 kilograms. It is a non-SI unit accepted for use with SI. It is also referred to as a metric ton to distinguish it from the non-metric units of the short ton ( United States customary units), and the long ton ( British imperial units). It is equivalent to approximately 2204.6 pounds, 1.102 short tons, and 0.984 long tons. The official SI unit is the megagram (symbol: Mg), a less common way to express the same mass. Symbol and abbreviations The BIPM symbol for the tonne is t, adopted at the same time as the unit in 1879.Table 6 . BIPM. Retrieved on 2011-07-10. Its use is also official for the metric ton in the United States, having been adopted by the United States |
