New data from NASA has revealed some information about the meteor that exploded over Chelyabinsk, Russia in 2013.

NASA found the meteor's orbital parent body had been struck one dozen times over its four billion year life, according to Forbes.

The meteor exploded over Chelyabinsk in February of 2013 and caused some chaos for a period. It is believed to have come from the main asteroid belt, and the scientists are continuing to study it to look for "near-Earth asteroidal impactors" that may have collided with it before it came toward Earth.

Understanding what is colliding with asteroids and where will help scientists understand which nearby asteroids are a threat to Earth.
