Some meteorites originate from the Moon. Impacts on the Moon’s surface catapult lunar meteorites into an orbit that crosses the orbit of the Earth. To escape the Moon’s gravitational field and finally land on Earth, meteorite must reach a speed of 8,600 km/h. Most lunar meteorites come from the lunar highlands. They contain fragments of different minerals and rocks (breccias). Meteorites originating from the lunar maria usually contain basaltic rock.
