WEBLunar meteorites, sometimes called lunaites, are meteorites from Earth’s moon. In other words, they are rocks found on Earth that were ejected from the moon by impacts of asteroidal meteoroids or possibly comets. How did lunar meteorites get here?
Lunar meteorite - Wikipedia
WEBA lunar meteorite is a meteorite that is known to have originated on the Moon. A meteorite hitting the Moon is normally classified as a transient lunar phenomenon. Discovery. In January 1982, John Schutt, leading an expedition in Antarctica for the ANSMET program, found a meteorite that he recognized to be unusual.
