Meteorite Find
A meteorite find is a meteorite that was found by people, but whose fall was not observed. They may have been on Earth's surface for as many as thousands of years and therefore could have been subject to varying amounts of weathering. Finds are distinguished from "meteorite falls", which are those which were observed during their descent and collected shortly afterwards. All officially recognized meteorites are listed in databases such as the Meteoritical Bulletin Database, most of which have specimens in modern collections.

Meteorite
A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or Natural satellite, moon. When the original object enters the atmosphere, various factors such as friction, pressure, and chemical interactions with the atmospheric gases cause it to heat up and radiate energy. It then becomes a meteor and forms a Meteoroid#Fireball, fireball, also known as a shooting star; astronomers call the brightest examples "Bolide#Astronomy, bolides". 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. Meteorites that are recovered after being observed as they transit the atmosphere and Impact event, impact the Earth are called meteorite falls. All others are known as meteorite finds.

Meteorite Weathering
Meteorite weathering is the terrestrial alteration of a meteorite. Most meteorites date from the oldest times in the Solar System and are by far the oldest material available on our planet. Despite their age, they are vulnerable to the terrestrial environment. Water, chlorine and oxygen attack meteorites as soon as they reach the ground. Weathering scales In order to quantify the degree of alteration that a meteorite experienced, several qualitative weathering indices have been applied to antarctic and desert samples.P. A. Bland, M. E. Zolensky, G. K. Benedix, M. A. Sephton. 'Weathering of Chondritic Meteorites'' The most known weathering scale is based upon the effects seen in polished thin sections of chondritic meteorites and it ranges from W0 (pristine) to W6 (heavy alteration). It was proposed by Jull A. J. T. et al. (1991) and updated by Wlotzka(1993) and Al-Kathiri et al.(2005). * W0: no visible oxidation of metal or troilite, but may be noticeable in transmitted light a ...

Meteorite Fall
A meteorite fall, also called an observed fall, is a meteorite collected after its fall from outer space was observed by people or automated devices. Any other meteorite is called a "find". There are more than 1,100 documented falls listed in widely used databases, most of which have specimens in modern collections. , the Meteoritical Bulletin Database had 1211 confirmed falls. Importance Observed meteorite falls are important for several reasons. Material from observed falls has not been subjected to terrestrial weathering, making the find a better candidate for scientific study. Historically, observed falls were the most compelling evidence supporting the extraterrestrial origin of meteorites. Furthermore, observed fall discoveries are a better representative sample of the types of meteorites which fall to Earth. For example, iron meteorites take much longer to weather and are easier to identify as unusual objects, as compared to other types. This may explain the increas ...

Meteoritical Bulletin Database
The Meteoritical Society is a non-profit scholarly organization founded in 1933 to promote research and education in planetary science with emphasis on studies of meteorites and other extraterrestrial materials that further our understanding of the origin and history of the Solar System. Members The membership of the society comprises over 1,000 scientists and amateur enthusiasts from over 52 countries who are interested in a wide range of planetary science topics. Members interests include meteorites, cosmic dust, asteroids and comets, natural satellites, planets, impact events, and the origins of the Solar System. Activities 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''.
