This meteorite above Russia apparently exploded with a power 30 times stronger than the Hiroshima nuclear bomb.
I understand that it gets hot from entering the atmosphere, and is quite big with a mass of 10000 tons, but still, it existed out of stone and iron, how can such "passive" material create such a huge explosion?
Also, it went at 15 km/s and exploded 30km above ground. If it exploded 2 seconds later it would have hit the ground. How likely was that?
