Talk about a precious stone ó the largest piece of the only known meteorite from the planet Mercury has found its way to Yale, where it is now on display at the Peabody Museum of Natural History.

Known as NWA 7325, the fist-size, greenish space rock is a rarity among rarities: there just arenít many verified planetary meteorites. Scientists know of about 70 from Mars and, until now, none from any of the other planets in Earthís solar system. There are about 180 known meteorites from the moon. NWA 7325 is the first believed to be from Mercury.


The magnetism of the meteorite formally known as NWA 7325 exactly matches that of Mercury.

ďIf itís not from Mercury, itís from a very interesting place,Ē said Anthony J. Irving, an expert in planetary meteorites at the University of Washington, during a recent appearance at the Peabody.

The meteoriteís chemical composition provides the strongest evidence that it came from Mercury, a rocky world that is the smallest planet in Earthís solar system and closest to the sun, Irving said. He noted the objectís high magnesium and chromium content and its low iron content are similar to those of Mercury. Also, the meteoriteís magnetism matches Mercuryís magnetism exactly, he said.

ďItís like ĎCSI Solar System,íĒ he said.

The NWA in the name stands for Northwest Africa. The meteorite was found in fragments in 2012 in the Moroccan desert. It is estimated to be 4.56 billion years old, about the age of Earth.
