(Metro) Astronomers say there's no danger when an asteroid cruises near our planet. 

The space rock, known as DA-14, will pass by the Earth at an altitude of 17-thousand miles, which is inside the orbit of most communications satellites.

NASA will begin live commentary with real-time animation of the flyby beginning at 2:00 p.m Eastern time on NASA TV and online at www.nasa.gov.intl.
