The El Ali meteorite (Arabic) or Ceel Cali (Somali) (known traditionally by the locals as Shiid-Birood and recently by the finders as Nightfall), 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.
Meteorite. The 60- tonne, 2.7 m-long (8.9 ft) Hoba meteorite in Namibia is the largest known intact meteorite. [1] A meteorite is a rock that originated in outer space and has fallen to 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 ...
Allan Hills 84001 (ALH84001[1]) is a fragment of a Martian meteorite that was found in the Allan Hills in Antarctica on December 27, 1984, by a team of American meteorite hunters from the ANSMET project. Like other members of the shergottite – nakhlite – chassignite (SNC) group of meteorites, ALH84001 is thought to have originated on Mars.
IIAB meteorites are a group of iron meteorites. Their structural classification ranges from hexahedrites to octahedrites. [2] IIABs have the lowest concentration of nickel of all iron meteorite groups. [3] Most iron meteorites are derived from the metallic planetary cores of their respective parent bodies, but in the case of the IIABs the ...
A micrometeorite is a micrometeoroid that has survived entry through the Earth's atmosphere. Usually found on Earth 's surface, micrometeorites differ from meteorites in that they are smaller in size, more abundant, and different in composition. The IAU officially defines meteoroids as 30 micrometers to 1 meter; micrometeorites are the small ...
Elaliite. Elaliite is a mineral with formula Fe9PO12 (or Fe2+8Fe3+(PO4)O8) that was first synthesized in a laboratory in the 1980s and later identified in natural material in 2022 at which time the official mineral designation was given. The mineral is orthorhombic, with space group Cmmm (space group 65). [1]
Muonionalusta meteorite. The Muonionalusta meteorite, on loan to the Prague National Museum in 2010. It is the largest meteorite ever exhibited in the Czech Republic. The Muonionalusta meteorite (Finnish pronunciation: [ˈmuo̯nionˌɑlustɑ], Swedish pronunciation: [mʉˈǒːnɪɔnalːɵsta]) [1] is a meteorite classified as fine octahedrite ...
Winonaite. Winonaites are a group of primitive achondrite meteorites. Like all primitive achondrites, winonaites share similarities with chondrites and achondrites. [1][2] They show signs of metamorphism, partial melting, brecciation and relic chondrules. Their chemical and mineralogical composition lies between H and E chondrites.
