Too close for comfort: Asteroid flyby today

A small asteroid is flying past Earth today inside the orbit of geosynchronous satellites and only 14,000 km above the surface of our planet. Named “2012 KT42,” the 3- to 10-meter wide space rock ranks #6 on the top-20 list of known close-approachers to Earth, which makes it significant despite its small size.  More information and images may be found on .
