Specimens of the Moon and Mars are among the rarest substances on Earth. Apollo astronauts brought back some pieces of the Moon, while others arrived on Earth as a result of asteroids slamming into the lunar surface. These impacts launch chunks of the Moon into outer space. Some of these pieces have Earth-intersecting orbits and become the most rare type of lunar meteorite. This specimen was intercepted falling in the Sahara Desert. Its scientific name is NWA 7834. It is the 7834th lunar rock recovered from the North West African corridor of the Sahara Desert that has been scientifically analyzed and classified.
