This is a list of largest meteorites on Earth. Size can be assessed by the largest fragment of a given meteorite or the total amount of material coming from the same meteorite fall: often a single meteoroid during atmospheric entry tends to fragment into more pieces. The table lists the largest meteorites found on the Earth's surface.
Items struck by meteorites also sell for high prices, such as a doghouse from Costa Rica that was struck by a meteorite. The dog wasn’t hit, and the corrugated sheet metal doghouse went on to ...
A meteorite mineral is a mineral found chiefly or exclusively within meteorites or meteorite-derived material. [ citation needed ] This is a list of those minerals, excluding minerals also commonly found in terrestrial rocks.
Its color ranges from bronze to brass yellow to silver white. It has a density of 7.5 and a hardness of 6.5 – 7. It is opaque with a metallic luster and a dark gray streak. It was named after the Austrian scientist Carl Franz Anton Ritter von Schreibers (1775–1852), who was one of the first to describe it from iron meteorites. [3]
Nonmagmatic meteorite (also nonmagmatic iron meteorite) is a deprecated term formerly used in meteoritics to describe iron meteorites that were originally thought to have not formed by igneous processes, to differentiate them from the magmatic meteorites, produced by the crystallization of a metal melt. [1]
Meteorite classification may indicate that a "genetic" relationship exists between similar meteorite specimens. Similarly classified meteorites may share a common origin, and therefore may come from the same astronomical object (such as a planet, asteroid, or moon) known as a parent body. However, with current scientific knowledge, these types ...
In 2000, near Fukang, China, a Chinese dealer obtained a mass from Xinjiang Province, China, with a weight of 1,003 kilograms (2,211 lb).He removed about 20 kilograms (44 lb) from the main mass, and in February 2005, the meteorite was taken to the Tucson Gem and Mineral Show, where it was seen by Dr. Dante Lauretta, a professor of Planetary Science and Cosmochemistry at the University of Arizona.
IVB meteorites formed the core of a parent body that was later destroyed, some of the fragments falling on Earth as meteorites. [3] Modeling the IVB parent body has to take into account the extreme chemical composition, especially the depletion of volatile elements (gallium, germanium) and the enrichment in refractory elements (iridium ...
