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 images were used both to determine the location of the stones on the ground and, more significantly, to calculate for the first time an accurate orbit for a recovered meteorite. Following the Příbram fall, other nations established automated observing programs aimed at studying infalling meteorites. One of these was the Prairie Network ...
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 Chelyabinsk meteorite (Russian: Челябинский метеорит, Chelyabinskii meteorit) is the fragmented remains of the large Chelyabinsk meteor of 15 February 2013 which reached the ground after the meteor's passage through the atmosphere.
The asteroid family that is the source region of CM chondrite-type meteorites is now thought to be located close to the 3:1 mean motion resonance, in low-inclined orbits, and may be the Eulalia asteroid family. [9] The meteorite type is similar to that of the 1969 Murchison meteorite in Australia. Unlike Murchison, Sutter's Mill shows clear ...
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
Allan Hills 84001 (ALH84001 [1]) is a fragment of a Martian meteorite that was found in the Allan Hills in Antarctica on December 27, 1984, by a team of American meteorite hunters from the ANSMET project. Like other members of the shergottite–nakhlite–chassignite (SNC) group of meteorites, ALH84001 is thought to have originated on Mars ...
The Murchison meteorite is a meteorite that fell in Australia in 1969 near Murchison, Victoria. It belongs to the carbonaceous chondrite class, a group of meteorites rich in organic compounds . Due to its mass (over 100 kg or 220 lb) and the fact that it was an observed fall , the Murchison meteorite is one of the most studied of all meteorites .
