A Mars meteorite stone (shergottite) weighing 245.4 grams.

Of the 60,000 or so meteorites that have been discovered on Earth, only 124 have been identified as originating from the planet Mars. These rare meteorites created a stir throughout the world when NASA announced in August 1996 that evidence of microfossils may be present in one of these Mars meteorites.

The meteorites in the table below are grouped by their pairings and listed roughly in the order that they were found.
