For the first time scientists have matched a meteorite found on Earth with a specific asteroid that became a fireball plunging through the sky. It gives them a glimpse into the past when planets formed and an idea how to avoid a future asteroid Armageddon.

Last October, astronomers tracked a small non-threatening asteroid heading toward Earth before it became a "shooting star," something they had not done before. It blew up in the sky and scientists thought there would be no space rocks left to examine.
