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 ". [ 1 ] [ 2 ] There are more than 1,300 documented falls listed in widely used databases, [ 3 ] [ 4 ] [ 5 ] most of which have specimens in modern collections.
A "meteorite fall", also called an "observed fall", is a meteorite collected after its arrival was observed by people or automated devices. Any other meteorite is called a "meteorite find". [43] [44] There are more than 1,100 documented falls listed in widely used databases, [45] [46] [47] most of which have specimens in modern collections.
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 ...
By Will Dunham. WASHINGTON (Reuters) - Meteorites - rocks that fall to Earth from space - have pelted our planet from its birth about 4.5 billion years ago to today, often causing scant damage but ...
UK scientists believe they have identified the source of one of the rarest meteorites to ever fall on Earth. The Ivuna meteorite landed in Tanzania in December 1938 and was subsequently split into ...
Several persons have since claimed to have been struck by "meteorites" but no verifiable meteorites have resulted. A small number of meteorite falls have been observed with automated cameras and recovered following calculation of the impact point. The first was the Příbram meteorite, which fell in Czechoslovakia (now the Czech Republic) in ...
“The Winchcombe meteorite is the most accurately recorded carbonaceous chondrite fall. Its pre-atmospheric orbit and cosmic-ray exposure age confirm that it arrived on Earth shortly after ...
Ordinary chondrites are by far the most common type of meteorite to fall to Earth: about 80% of all meteorites and over 90% of chondrites are ordinary chondrites. [11] They contain abundant chondrules, sparse matrix (10–15% of the rock), few refractory inclusions, and variable amounts of Fe–Ni metal and troilite (FeS). Their chondrules are ...
