Everything you ever wanted to know about the 2013 Chelyabinsk bolide. It was a large meteor/small asteroid about 60 feet across and traveling at an estimated 40,000 mph. It released maybe 500 kilotons of energy (equivalent to a significant nuclear weapon, 25-33X the size of the Hiroshima bomb), albeit at very high altitude. More than a thousand people were injured badly enough to require medical attention and some 7,000 buildings were damaged (mostly broken windows from the shockwave). The light it gave off was brighter (but whiter) than the Sun.

The video below includes a whole bunch of extraordinary video footage put together by
Russia Today, one after another, showing this thing from all angles from all over this Soviet-style heavy industrial city. The thing's trajectory in from space, the blinding nuclear style flash, windows getting blown in, people's responses inside stores and offices, pretty dramatic.
This is the best documented event of its kind, ever.

From how it looked, I probably would have believed it was a nuclear attack too, just like they did.
