A meteorite is a portion of a meteoroid or asteroid that survives its passage through the atmosphere and hits the ground without being destroyed. [22] Meteorites are sometimes, but not always, found in association with hypervelocity impact craters; during energetic collisions, the entire impactor may be vaporized, leaving no meteorites.
Meteoritics [note 1] is the science that deals with meteors, meteorites, and meteoroids. [note 2] [2] [3] It is closely connected to cosmochemistry, mineralogy and geochemistry. A specialist who studies meteoritics is known as a meteoriticist. [4]
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. [2] Meteorites that are recovered after being observed as they transit the atmosphere and impact Earth are called meteorite falls.
Fossil meteorite – a meteorite that was buried under layers of sediment before the start of the Quaternary period. Some or all of the original cosmic material has been replaced by diagenetic minerals. [3]: 320 (It is, however, not a fossil). Fusion crust – a coating on meteorites that forms during their passage through the atmosphere.
A giant meteorite first discovered in 2014 caused a tsunami bigger than any in known human history and may have sparked life, scientists reveal. A giant, ancient meteor four times the size of ...
It was during daytime hours and was witnessed by many people, which allowed V. G. Fesenkov, then chairman of the meteorite committee of the USSR Academy of Science, to estimate the meteoroid's orbit before it encountered the Earth. Sikhote-Alin is a massive fall with the overall size of the meteoroid estimated at 90,000 kg (200,000 lb).
