OH God! we are safe: The Mid-Size Asteroid Won't hit the Earth

The world would be hit like this by Asteroid 2012 Da14  At last NASA calculates out that the near-Earth asteroid 2012 DA14 won't hit our home planet in 2013 as it speculated before. NASA researchers say. The asteroid, which astronomers estimate to be about 150 feet (45 meters) across, will give Earth an uncomfortably close shave on Feb. 15, 2013, coming nearer to our planet than the satellites we've lofted to geostationary orbit. But 2012 DA14 poses no real impact danger on that pass, according to NASA scientists. "Its orbit about the sun can bring it no closer to the Earth's surface than 3.2 Earth radii on February 15, 2013," researchers with the Near-Earth Object Program Office, at NASA's Jet Propulsion Laboratory in Pasadena, Calif., wrote in an update today (March 6). One Earth radius is roughly 3,963 miles (6,378 kilometers) at the equator. So by this reckoning, the nearest 2012 DA14 can get to us next year is 12,680 miles (20,406 km). For comparison, satellites in geosynchronous orbit circle our planet ...
