A meteor that shattered over Chelyabinsk, Russia, today injured some 500 people, with 34 hospitalized. The 10-ton meteor was traveling at least 33,000mph when it entered the atmosphere, experts say.
The explosion occurred between 18 and 32 miles from ground level near the Ural Mountains. Shock-waves damaged buildings, breaking glass that caused most of the injuries. Some meteorites—fragments from the meteor—eventually landed near a lake.
Meteors typically cause sizable sonic booms when they enter the atmosphere because they are traveling much faster than the speed of sound; however, a widespread meteor-related injuries like today’s are very rare.
