Bill Nye on Twitter: "It’s the anniversary of the Chelyabinsk meteorite impact, which was no joke. Low probability-- very high consequence. Check out the @exploreplanets asteroid defense plan at [url]https://t.co/25CvHfErZE… https://t.co/zfI04CeJBO"[/url]

On 15 February 2013, 09:20 YEKT (UTC+06:00), the
Chelyabinsk meteor fell near that Russian city near the Ural Mountains. Its sonic boom smashed a lot of windows and made a factory roof collapse, damaging some 7200 buildings. It also caused some 1500 injuries among nearby people, though no deaths were reported. As it fell, it broke up and it left behind a trail of dust, and numerous fragments of it have been recovered. Its initial mass was somewhere around 12,000–13,000 metric tons, its initial diameter around 20 m / 66 ft, and its explosive force was some 400 - 500 kilotons of TNT, comparable to a big nuclear bomb.
It is the biggest known object to hit our planet's atmosphere since the 1908 Tunguska disaster, an event which had nearly 100 times more explosive force.
