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 .
Winonaites and the two iron meteorite groups IAB and IIICD are thought to be derived from the same parent body. The iron meteorites formed part of the core of the planetesimal and the winonaites were closer to the surface. The reasoning is that the silicate inclusions in IAB meteorites are similar to winonaites, especially in their oxygen ...
Meteorite fall statistics are frequently used by planetary scientists to approximate the true flux of meteorites on Earth. Meteorite falls are those meteorites that are collected soon after being witnessed to fall, whereas meteorite finds are discovered at a later time. Although there are 30 times as much finds than falls, their raw ...
Nakhla meteorite's two halves, showing its inner surfaces after being broken in 1998 Nakhlites are a group of Martian meteorites , named after the first one, Nakhla meteorite . Nakhlites are igneous rocks that are rich in augite and were formed from basaltic magma about 1.3 billion years ago.
The Meteoritical Society is the organization that records all known meteorites in its Meteoritical Bulletin.The Society also publishes one of the world's leading planetary science journals, Meteoritics & Planetary Science, and is a cosponsor with the Geochemical Society of the renowned journal Geochimica et Cosmochimica Acta.
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 ).
NASA says four radar sweeps detected “signatures consistent with falling meteorites seen at the time and location reported by eyewitnesses,” and people also heard sonic booms. Museum offers ...
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 ...
