Meteorite Injures Nearly 1,000 Russians

UPDATE:
MOSCOW (AP) - Interfax says nearly 1,000 people injured by falling meteor in Russia, according to officials.

BERLIN (AP) - A meteor exploded in the sky above Russia on Friday, injuring hundreds of people as its fragments fell to the ground in the Ural Mountains. Here's a look at those objects in the sky:

What's the difference between a meteor and a meteorite?
Meteors are pieces of space rock, usually from larger comets or asteroids, which enter the Earth's atmosphere. Many are burned up by the heat of the atmosphere, but those that survive and strike the Earth are called meteorites. They often hit the ground at tremendous speed - up to 30,000 kilometers an hour (18,642 mph) according to the European Space Agency. That releases a huge amount of force.
How common are meteorite strikes?
Experts say smaller strikes happen five to 10 times a year. Large impacts such as the one Friday in Russia are rarer but still occur about every five years, according to Addi Bischoff, a mineralogist at the University of Muenster in Germany. Most of these strikes happen in uninhabited areas where they don't cause injuries to humans.
Is there any link to the asteroid fly-by taking place later Friday?
No, it's just cosmic coincidence, according to European Space Agency spokesman Bernhard Von Weyhe, who says Asteroid 2012DA14 is unrelated to the meteorite strike in Russia.
When was the last comparable meteorite strike?
In 2008, astronomers spotted a meteor heading toward Earth about 20 hours before it entered the atmosphere. It exploded over the vast African nation of Sudan, causing no known injuries. The largest known meteorite strike in recent times was the "Tunguska event" that hit Russia in 1908. Even that strike, which was far bigger than the one that happened over Russia on Friday, didn't injure anyone. Scientists believe that an even larger meteorite strike may have been responsible for the extinction of the dinosaurs about 66 million years ago.
What can scientists learn from Friday's strike?
Bischoff says scientists and treasure hunters are probably already racing to find pieces of the meteorite. Some meteorites can be very valuable, selling for up to €500 ($670) per gram depending on their exact composition. Because meteors have remained largely unchanged for billions of years - unlike rocks on Earth that have been affected by erosion and volcanic outbreaks - scientists will study the fragments to learn more about the origins of matter.
What would happen if a meteorite hit a major city?
Scientists hope never to find out, but they're still trying to prepare for such an event. Von Weyhe, the European space agency spokesman, says experts from Europe, the United States and Russia are already discussing how to spot potential threats sooner and avert them.
"It's a global challenge and we need to find a solution together," he said. "But one thing's for sure, the Bruce Willis "Armageddon" method won't work."
 

MOSCOW (AP) - A thick white contrail, an intense flash and sharp explosions marked the passage today of a meteor across the sky above Russia's Ural Mountains, where more than 400 people have reported injuries, many from broken glass.

The Emergency Ministry says fragments of the meteorite fell in a thinly populated area of the Chelyabinsk region. And about 6000 square feet of a roof at a zinc factory collapsed.

A ministry spokeswoman calls the event a meteor shower while another ministry official says it was a single meteorite.

The event was captured on amateur video.
