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 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.
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 Some or all of the original cosmic material has been replaced by diagenetic minerals.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.
Harvey Harlow Nininger (January 17, 1887 – March 1, 1986) was an American meteoriticist and educator. Although he was self-taught, he revived interest in scientific study of meteorites in the 1930s and assembled the largest personal collection of meteorites up to that time.
The journal was established as Meteoritics in 1953, adopting its current name when the scope was broadened in 1996. Since January 1, 2003, the editor-in-chief is A.J. Timothy Jull (Arizona Accelerator Mass Spectrometry Laboratory).
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 ...
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 ...
Some fragments may impact Earth as meteorites, if the meteor starts to break up or explodes in mid-air. These phenomena are then called Earth-grazing meteor processions and bolides . [ 1 ] Famous examples of Earth-grazers are the 1972 Great Daylight Fireball and the Meteor Procession of July 20, 1860 .
