Don’t Fear the Sky Reaper.
A small meteorite exploded near the Russian town of Chelyabinsk, just as DA14, an asteroid that is 150 feet wide was set to pass nearby earth. The meteorite did not break off of DA14, it was the remains of a much smaller object that entered earth’s atmosphere. The importance of this is that this meteorite was one of the countless number of small space debris that is not tracked.
