NASA provides more Russian meteor explanations

Space agency discovers where meteor came from - different asteroid than the fly-by one

By  

We continue to see reports and videos from the Russian meteor that crashed near Chelyabinsk, Russia a few weeks ago, which also caused a flood of videos to hit YouTube and generate millions of views from around the world.

NASA's "ScienceAtNASA" YouTube channel has posted a new video that offers up more details on the meteor, including our ability to discover where it came from - not the DA14 asteroid that was doing the close-Earth flyby later that day, but rather from the asteroid belt near Mars.

If you're interested in more about the Russian meteor, check out this blog post from William Cooke - the NASA scientist explains why we couldn't detect the meteor before it entered the atmosphere. Basically, it was too small for us to see. Yikes.
