Russia Meteor Updates: 10-Ton Space Rock Explodes Over Ural Mountains (LIVE UPDATES)

A meteor estimated to weigh 10 tons exploded near the Ural mountains in Russia Friday, injuring nearly 1000 people and causing extensive property damage.

Footage of the meteor blazing across the sky and bursting into a ball of light over the mountain range has since been widely shared online.

The meteor has no connection to asteroid DA14, which is expected to pass within 17,200 miles of Earth on Friday, according to NASA scientist Don Yeomans.

How Often Do Impacts Of This Magnitude Hit Earth?

"The Earth is constantly bombarded by objects from space but mostly by much smaller rocks. Rocks that are this size (5-15 meters) statistically impact the Earth once every 5 - 30 years or so, depending on the size. But the Earth is mostly covered by ocean water so the events would not be noticed as often," MSU professor Edwin Bergin writes.

Five Times Smaller

@ KairaProject :

Size comparison? Asteroid 2012 #DA14 is approximately five times the size of #RussianMeteor Confirming #DA14 size now

Why Radar Did Not Detect The Meteor

Edwin Bergin, a professor of astronomy at the University of Michigan, explained further why the Russian meteor was not detected by radar in an email to the Huffington Post.

"Objects such as this one," Bergin wrote, "are difficult to detect with our current telescopes, which are geared to find objects of sizes 50-100 meters and larger. In general the larger objects, of km-size, are much easier to detect. Given the km-sized bodies' potential for greater devastation (think the extinction of dinosaurs), we certainly are attempting to detect objects that might impact the Earth. However, the effort is by no means complete. To do it right we need full Earth coverage for our telescopes and right now that is not the case."

Russian Meteor And Asteroid DA14 Are Definitely Not Linked

Pressed further on why the Russian meteor and asteroid DA14 are not linked, NASA's Paul Chodas explained: "Our estimates are based on things like the direction of approach, which we believe was approximately north to south."

"Another reason, the velocity was much, more greater than the velocity of a remnant like DA14," Chodas said.

Mid-Air Explosion

According to NASA's Bill Cooke, the Russian meteor exploded 12 to 15 miles above ground in a mid-air blast.

Focused On The Large Asteroids

Paul Chodas, a research scientist in the Near Earth Object Program Office at NASA's Jet Propulsion Laboratory, explains that NASA is focused on the large asteroids, first and foremost.

"Although the smaller ones are easier to divert, they are very difficult to detect," Chodas said.

Why NASA Didn't See The Meteor

@ JoelAchenbach :

NASA's explanation for not seeing Russian asteroid in advance is, literally, "The sun was in our eyes." #meteor

300-Mile Trail

"The meteor was about 30 seconds, it was moving approximately 10 miles per second, so it left a trail about 300 miles long," NASA's Bill Cooke said.
