On February 15, Asteroid 2012 DA14, a 150-feet cosmic rocky object, will pass within 17,000 miles of Earth's surface — below the 22,236-mile altitude where major weather and communications satellites operate, but above low-Earth orbit where the International Space Station operates.
According to specialists, the object presents no threat to either Earth or satellites. However, n ext week's "fly-by" will be the closest that an object of such size has passed the planet (objects in this size come this close about once every 40 years, on average, and collide with Earth at an average rate of one every 1,200 years).
Where to Watch:
According to LA Times, people in the Eastern Hemisphere may be able to spot the asteroid zoom by with the help of strong binoculars or a small telescope. However, NASA will provide a Ustream feed of the flyby from a telescope at the Marshall Space Flight Center in Alabama (the broadcast starts at 3:00 p.m. and goes until 6:00 p.m. (PST) on February 15. Slooh.com will also be streaming live images from two observatories of the flyby (also goes from 3:00 to 6:00 p.m. PST). Similarly, The Clay Center Observatory in Brookline, Massachusetts, will live streaming from the observatory's Ustream channel.
