Record-setting asteroid to shave past Earth this month

An asteroid about half the size of a football field will zoom past Earth on Feb. 15, closer than the man-made satellites that power GPS, says NASA.

"This is a record-setting close approach," Don Yeomans of NASA's Near Earth Object Program at JPL said in a video released by NASA this week. Yeomans, however, emphasized that the asteroid, designated 2012DA14, won't hit Earth. 

"It will come interestingly close, closer than many man-made satellites," he said. 

2012DA14 will thread the gap between low earth orbit, where the International Space Station and many earth observation satellites are located and the higher belt of geosynchronous satellites, which provide weather data and telecommunications. 

At its closest point, the asteroid will only be 17,200 miles above our planet's surface. 

"The odds of impact with a satellite are extremely remote," Yeomans adds. "Almost nothing orbits where DA14 passes the Earth. 

At 50 meters wide, the asteroid is "neither very large nor very small" and is probably made of stone as opposed to ice or metal. Yeomans estimates that an asteroid flies past Earth, on average, every 40 years, yet actually hits the planet once every 1200 years or so.
