A meteor with estimated mass of 10,000 tons by NASA (on entry to Earth’s atmosphere) exploded Friday morning over Russia’s Ural region and its shock-wave caused injuries to over 1,000 people. It took out windows and walls in the city of Chelyabinsk.
Some years ago, I personally witnessed a much smaller fireball, and I was convinced I was seeing an airplane crash.
On the same day, Friday 15th February 2013, skimming closer to the earth than any other asteroid of its size, Asteroid 2012 DA14 missed us by 17,100 miles, a margin closer than some satellites.
