Newfound Asteroid to Buzz Earth Thursday

A newly discovered asteroid will zip close by Earth Thursday, but poses no threat of crashing into our planet even though it is passing within the orbit of the moon.
The asteroid, called 2010 GA6, is a relatively small space rock about 71 feet wide and was discovered by astronomers with the Catalina Sky Survey in Tucson, Az. The space rock will fly within the orbit of the moon when it passes Earth Thursday at 7:06 p.m. EDT (2306 GMT), but NASA astronomers said not to worry...the planet is safe.
