An asteroid half the size of a football field will give Earth the ultimate close shave this month, passing closer than many satellites when it whizzes by, but it won't hit the planet, NASA scientists say.
The asteroid 2012 DA14 will fly by Earth on Feb. 15 and zip within 17,200 miles (27, 680 kilometers) of the planet during the cosmic close encounter. The asteroid will approach much closer to Earth than the moon, and well inside the paths of navigation and communications satellites.
"This is a record-setting close approach," Don Yeomans, the head of NASA's asteroid-tracking program, said in a statement. "Since regular sky surveys began in the 1990s, we've never seen an object this big get so close to Earth."
