(523775) 2014 YB35
(523775) 2014 YB35, provisional designation 2014 YB35, is a stony near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 300 meters (980 feet) in diameter. It was discovered on 27 December 2014 by the Catalina Sky Survey at the Catalina Station in Arizona, United States. In March 2015, a minor-planet moon, less than half the size of its primary, was discovered by radar astronomers at Goldstone Observatory. The primary body of the binary system has a rotation period of 3.3 hours, while the secondary's orbital period remains unknown.
