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.
For most meteorite falls, even those that occurred long ago or for which material has never received complete scientific characterization, it is known whether the object was a stone, stony iron, or iron meteorite. Here are the numbers and percentages of each type, based on literature data. [2] [3] [4]
Most recorded impact craters are over 10 million years old, or have widely uncertain ages. The Chicxulub impact has been widely considered the most likely cause for the Cretaceous–Paleogene mass extinction , with some scholars linking other impacts like the Popigai impact in Russia and the Chesapeake Bay impact to later extinction events ...
Although meteorites had been sold commercially and collected by hobbyists for many decades, up to the time of the Saharan finds of the late 1980s and early 1990s, most meteorites were deposited in or purchased by museums and similar institutions where they were exhibited and made available for scientific research. The sudden availability of ...
There are several lists of meteorite impacts of various types available: Category:Lists of impact craters contains lists on various planets, including Earth by continent; Meteorite falls are observed; Meteorite finds are rocks found on the ground which are geologically identified as meteorites; Meteorite contains lists of the most notable of ...
By studying the composition of meteorites that have landed over the years and the asteroids populating our solar system, astronomers have determined that about 70% of known meteorite impacts came ...
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.
“For most meteorites the challenge we have is that they are just contaminated, whereas with Winchcombe we really know that it really hasn’t been contaminated, so it’s good evidence.”
