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.
As the meteor, traveling at a speed of about 14 km/s (8.7 mi/s), entered the atmosphere, it began to break apart, and the fragments fell together, some burying themselves 6 metres (20 ft) deep. [3] At an altitude of about 5.6 km (3.5 mi), the largest mass apparently broke up in an explosion called an air burst .
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.
On 8 September 2021, 1 square metre (11 sq ft) of the indented section of asphalt driveway where the meteorite landed was removed and taken to London's Natural History Museum. [ 10 ] Pieces of the Winchcombe meteorite are now part of a display in the Winchcombe Museum, which tells the story of its origins, unexpected arrival and its scientific ...
Sixteen separate video recordings document the meteorite burning through the Earth's atmosphere, whereupon it struck a parked car in Peekskill. [2] The Peekskill meteorite is an H6 monomict breccia ; [ 3 ] [ 4 ] its filigreed texture is the result of the shocking and heating following the impact of two asteroids in outer space. [ 5 ]
The impactor belonged to the Apollo group of near-Earth asteroids. [10] [11] The asteroid had an approximate size of 18 m (59 ft) and a mass of about 9,100 t (10,000 short tons) before it entered the denser parts of Earth's atmosphere and started to ablate. [12] At an altitude of about 23.3 km (14.5 miles) the body exploded in a meteor air ...
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 ...
The 90.6-kilometer-long (56.3 mi) trace of the Neuschwanstein meteor within the Earth's atmosphere began at a height of about 85 km (53 mi), about 10 km (6 mi) east-northeast of Innsbruck, with an entry angle of about 49° to the horizontal, and ended 16.04 km (10.0 mi) above the Earth's surface. Shortly before that it split into fragments at ...
