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. [2]
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 size of the chondrules range from "a few hundred microns to more than two millimeters across". The meteorite is categorized as petrographic type 5/6. According to the study ...
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 ...
