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 .

2024 BX 1, previously known under its temporary designation Sar2736, was a 44 centimetre-sized (17 inches) [4] asteroid or meteoroid that entered Earth's atmosphere on 21 January 2024 00:33 UTC and disintegrated as a meteor over Berlin. [2] [7] The recovered fragments are known as the Ribbeck meteorite.
The group takes its name from Mighei (Ukraine), but the most famous member is the extensively studied Murchison meteorite. Many falls of this type have been observed and CM chondrites are known to contain a rich mix of complex organic compounds such as amino-acids and purine/pyrimidine nucleobases.

The meteorite type is similar to that of the 1969 Murchison meteorite in Australia. Unlike Murchison, Sutter's Mill shows clear brecciation: fragments of CM lithologies with different aqueous alteration and thermal processing histories are embedded in a fine grained CM matrix material. The Sutter's Mill meteorite originated from near the ...
