Asteroid 2012 DA14 to pass through Earth’s Satellite Belt :

A small near-Earth asteroid was discovered in late February 2012 by astronomers at the Observatorio Astronómico de La Sagra in Spain, designated 2012 DA14, is estimated to be about 45 meters (150 feet) in diameter, and has an orbit that is similar to Earth’s.
The asteroid will pass by our planet in February 15, 2013 at a distance of under 27,000 km (16,700 miles). This is closer than the geosynchronous orbit of some satellites.
There is a possibility the asteroid will collide with Earth, but further calculation is required to estimate the potential threat and work out how to avert possible disaster, said NASA expert Dr. David Dunham told students at Moscow’s University of Electronics and Mathematics (MIEM).
