Meteor Strike in Russia Injures 500 People: Reports
More than 500 people are reportedly injured, and hundreds of buildings damaged, after a meteorite streaked across the sky above Russia’s Ural Mountains Friday morning (Feb. 15) and exploded in a massive blast.
The meteor explosion was centered around the Chelyabinsk region, which is about 930 miles (1,500 kilometers) east of Moscow.
Most of the hundreds injured were reportedly hurt by falling glass in the blast, 112 of whom have been hospitalized, due to cuts from the shattered glass resulting from the blast. In addition, an estimated 297 buildings were damaged, including six hospitals and 12 schools, according to translations of updates by the Russian Emergency Ministry.
Scientists think a meteoroid entered the atmosphere above Russia’s southern Chelyabinsk region, where it exploded and broke up into meteorites scattered across three regions of Russia and Kazakhstan, according to news reports.
“I would think that this is likely an exploding fireball (or bolide) event caused by the atmospheric impact of a small asteroid,” Don Yeomans, head of NASA’s Near-Earth Object Program, told SPACE.com. “If the reports of ground damage can be verified, it might suggest an object whose original size was several meters in extent before entering the atmosphere, fragmenting and exploding due to the unequal pressure on the leading side vs. the trailing side.”
Basically, Yeomans added, the meteor “pancaked and exploded.”
(A bolide is an extraterrestrial body ranging in size from 0.6 to 6 miles, or 1-10 km across that hits Earth at velocities faster than a speeding bullet, according to the U.S. Geological Survey.)
“This bolide event probably had nothing to do with the upcoming close Earth approach of asteroid 2012 DA14, which is due to pass closely (and safely) past the Earth at 19:24 GMT today,” or 2:24 p.m. ET, Yeomans wrote, adding that the Russian bolide trail did not travel south to north as the asteroid will.
“And the separation in time between the fireball and 2012 DA14 close approach is significant,” Yeomans said.
NASA said via Twitter that there is no relationship between the meteorite and 2012 DA14. “On very different paths. DA14 misses us today,” NASA said.
A large chunk of the space rock has reportedly been discovered in a lake in the Chelyabinsk region, CNN reports.
A report by the Russian television news agency Russia Today showed video of the meteor, which included what appears to be a fireball streaking across the sky from several vantage points. At times the object is so bright it casts shadows.
In 1908, a fireball exploded over the Tunguska River in Siberia, Russia, flattening hundreds of square miles of land during a massive blast. That fireball was created by the explosion of an object about 150 feet (45 meters) across, NASA scientists have said.
A similarly sized object, the asteroid 2012 DA14, will fly extremely close to Earth on Friday, but will not hit the planet. The asteroid will approach within 17,200 miles (27,000 kilometers) of the Earth —about 5,000 miles (8,046 km) closer than geosynchronous satellites —during the close shave.
Asteroid 2012 DA14 was discovered in February 2012 and is being closely tracked by NASA and astronomers around the world. The asteroid is about half the size of a football field, but will not be visible to the naked eye when it flies by on Friday. A small telescope or binoculars, very dark skies and good timing will be needed to see the fast-moving asteroid.
