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 .
The Middlesboro crater (or astrobleme) is a meteorite crater in Kentucky, United States. [2] It is named after the city of Middlesboro, Kentucky, which today occupies much of the crater. The crater is approximately 3 miles (about 5 km) wide and its age is estimated to be less than 300 million years . The impactor is estimated to have been about ...

A meteorite is a portion of a meteoroid or asteroid that survives its passage through the atmosphere and hits the ground without being destroyed. [21] 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.
LL chondrites, LL chondrite meteorites, Amphoterites The LL chondrites are a group of stony meteorites , the least abundant group of the ordinary chondrites , accounting for about 10–11% of observed ordinary-chondrite falls and 8–9% of all meteorite falls (see meteorite fall statistics ).
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. [5] 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 (31 long tons; 34 ...
