A Martian meteorite is a rock that formed on Mars, was ejected from the planet by an impact event, and traversed interplanetary space before landing on Earth as a meteorite. As of September 2020[update], 277 meteorites had been classified as Martian, less than half a percent of the 72,000 meteorites that have been classified.[1] The largest complete, uncut Martian meteorite, Taoudenni 002,[3] was recovered in Mali in early 2021. It weighs 14.5 kilograms (32 pounds) and is on display at the Maine Mineral and Gem Museum.
