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.
The 3rd largest meteorite fall of the 20th century. A huge, brilliant fireball lit the sky and ground for hundreds of miles. It exploded and broke up. About 2 tons of fragments were later found. [42] 1972, Apr 14 Indian Ocean: 14 kilotonnes of TNT (59 TJ) Infrasound detection. [43] 1976, Mar 8
Between 1911 and 1913, 33 fragments of the meteorite were collected in the vicinity of Gibeon and brought to the capital Windhoek. They weighed between 195 and 506 kilograms (430 and 1,116 lb) and were first stored, then displayed at the Zoo Park as a single heap. In 1975 a public fountain displaying the meteorite fragments was planned.
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 ...
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.
The Winchcombe meteorite is a rare find, with a similar hydrogen isotope ratio to the water on Earth.. Recovering a meteorite within 12 hours of arrival means it is as pristine a specimen as we ...
This is a list of largest meteorites on Earth. Size can be assessed by the largest fragment of a given meteorite or the total amount of material coming from the same meteorite fall: often a single meteoroid during atmospheric entry tends to fragment into more pieces. The table lists the largest meteorites found on the Earth's surface.
The Chelyabinsk meteor was later determined to come from the LL chondrite group. [92] The meteorites were LL5 chondrites having a shock stage of S4, and had a variable appearance between light and dark types. Petrographic changes during the fall allowed estimates that the body was heated between 65 and 135 degrees during its atmospheric entry. [93]
