Martian meteorite NWA 7034, nicknamed "Black Beauty," weighs approximately 320 g (11 oz). [2] 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, 277 meteorites had been classified as Martian, less than ...
