A 10-ton meteorite streaked across the sky and exploded over central Russia, raining fireballs over a vast area and causing a shock wave that smashed windows, damaged buildings and injured 1,200 people. People heading to work in Chelyabinsk (about 950 miles east of Moscow) heard what sounded like an explosion, saw a bright light and then felt the shock wave. The fireball, travelling at a speed of 19 miles per second had blazed across the horizon, leaving a long white trail that could be seen as far as 125 miles away.
