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". [42] [43] There are more than 1,100 documented falls listed in widely used databases, [44] [45] [46] 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 ...
Pallasites are a rare type of meteorite. Only 61 are known to date, including 10 from Antarctica, with four being observed falls. [9] [10] The following four falls are in chronological order: Mineo, Sicily, Italy. A luminous meteor was observed and an object seen to fall with a loud roar in May 1826. Only 46 grams (1.6 oz) are preserved in ...

Though the meteorite impact theory of tektite formation is widely accepted, there has been considerable controversy about their origin in the past. As early as 1897, the Dutch geologist Rogier Diederik Marius Verbeek (1845–1926) suggested an extraterrestrial origin for tektites: he proposed that they fell to Earth from the Moon.
Sikhote-Alin is a massive fall, with the pre-atmospheric mass of the meteoroid estimated at approximately 90,000 kg (200,000 lb). [7] A more recent estimate by Tsvetkov (and others) puts the mass at around 100,000 kg (220,000 lb).
