2000 EM26 is a sub-kilometer near-Earth object and potentially hazardous asteroid of the Aten group, approximately 110 meters (360 feet) in diameter. It was first observed by astronomers of the LINEAR program on 5 March 2000 and followed until 14 March 2000, by which time it had dimmed to apparent magnitude 20[1] and was 40° from the Moon.[5] By 17 March 2000 it was only 4 degrees from a 90% waxing gibbous moon.[5] It has never been listed on the Sentry Risk Table because none of the potential orbital solutions create a risk of impact in the next ~100 years. The asteroid safely passed Earth on 17–18 February 2014.[6] Due to a then-poorly determined orbit, the asteroid may have been significantly further from Earth and dozens of degrees from where the telescope was pointed during the 2014 approach.
