Graphic showing 2014 UR116 & Earth Asteroid 2014 UR116, A 400-meter Sized Near-Earth Asteroid, Represents No Threat to the Earth
December 8, 2014

Some recent press reports have suggested that an asteroid designated 2014 UR116 represents an impact threat to the Earth. The asteroid does not represent a threat because it's orbital path does not pass sufficiently close to the Earth's orbit.
