2014 HQ124 is a sub-kilometer asteroid, classified as near-Earth object and potentially hazardous asteroid of the Aten group, approximately 400 meters (1,300 feet) in diameter. It passed 3.25 lunar distances (LD) from Earth on 8 June 2014.[8] It was discovered on 23 April 2014 by NEOWISE.[2] It is estimated that an impact event would have had the energy equivalent of 2,000 megatons of TNT and would have created a 5 km (3 mi) impact crater.[9] The news media misleadingly nicknamed it The Beast.[10] 2014 HQ124 previously passed this close to Earth in 1952[8] and will not again until at least 2307.[11] Radar imaging suggests it may be a contact binary.[12]
