  2. Where did the Russian meteorite come from? Most likely from the asteroid belt between Mars and Jupiter. 

    Poring over crowd-sourced footage, researchers Jorge Zuluaga and Ignacio Ferrin from the University of Antioquia in Medellin, Colombia, were able to use “simple trigonometry to calculate the height, speed, and position of the rock as it fell to Earth,” says BBC NewsMore importantly, the duo was able to find out where Russia’s most famous meteorite was likely born.

    Using astronomy software developed by the U.S. Naval Observatory, Zuluaga and Ferrin gathered enough data to trace the meteorite’s origins in outer space. The information included the meteorite’s relative angle to the horizon, the shadows it cast, and video timestamps of the rock’s screaming descent.

  3. Meteors are space rocks that find their way into Earth’s atmosphere. They can be as small as a grain of sand or as big as a boulder. They usually burn up during their descent. The ones that survive are called meteorites, and they can hit the Earth at speeds of up to 18,600 mph.

  4. The Chelyabinsk region of Russia, in the Ural Mountains about 930 miles east of Moscow, was pelted by at least one meteorite on Friday, freaking out residents with bright streaks across the sky and loud, window-shaking explosions.

    No serious injuries have been reported from the blasts, and Russian authorities are providing slightly different explanations for what happened. The growing consensus is that a meteorite exploded about 32,000 feet in the air, scattering smaller chunks around the region. “Verified information indicates that this was one meteorite which burned up as it approached Earth and disintegrated into smaller pieces,” Russian Emergency Ministries official Elena Smirnykh tells Russia’s RIA Novosti.

    There’s some amazing video footage emerging after the explosions. Watch.
