Meteorite comes into Earth's Atmosphere over Siberia (VIDEO)
The Russian Academy of Sciences is estimating the meteor that streaked into the skies over the Ural Mountains and caused shock waves that injured more than 400 people weighed about 10 tons.
The academy says the meteor entered the Earth's atmosphere at a speed of at least 33,000 mph and shattered about 18-32 miles above ground.
The fall caused explosions that broke glass over a wide area. The Emergency Ministry says more than 500 people sought treatment after the blasts and that 34 of them were hospitalized.
