Meteorites start out as bits of rock or metal in space — usually from asteroids, and sometimes even from the Moon or Mars. Occasionally, a collision knocks one loose and sends it on a new path as a meteoroid. If it enters Earth’s atmosphere, it becomes a meteor, and if it survives the fiery trip and lands on the ground, it becomes a meteorite.
So when you hold a meteorite, you’re holding something that’s traveled millions of miles through space to reach you!
