June 10, 2013 – CAPE CANAVERAL, Florida – An asteroid the size of a small truck zoomed past Earth four times closer than the moon on Saturday, the latest in a parade of visiting celestial objects that has raised awareness of potentially hazardous impacts on the planet. NASA said Asteroid 2013 LR6 was discovered about a day before its closest approach to Earth, which occurred at 12:42 a.m. EDT (0442 GMT on Saturday) about 65,000 miles over the Southern Ocean, south of Tasmania, Australia. The 30-foot-wide (10-meter-wide) asteroid posed no threat.
