(523775) 2014 YB35, provisional designation2014 YB35, is a stonynear-Earth object andpotentially hazardous asteroid of theApollo group, approximately 300 meters (980 feet) in diameter. It was discovered on 27 December 2014 by theCatalina Sky Survey at theCatalina Station inArizona,United States.[1] In March 2015, aminor-planet moon, less than half the size of its primary, was discovered by radar astronomers atGoldstone Observatory.[3] The primary body of thebinary system has arotation period of 3.3 hours, while the secondary's orbital period remains unknown.[8]
2014 YB35 is a member of theApollo asteroids, a group of near-Earth object with an Earth-crossing orbit. It orbits the Sun at a distance of 1.0–2.8 AU once every 2 years and 7 months (939 days;semi-major axis of 1.88 AU). Its orbit has aneccentricity of 0.48 and aninclination of 13° with respect to theecliptic.[2] The body'sobservation arc begins at with its official discovery observation at Catalina Station in December 2014.[1]
It passed by Earth on 27 March 2015 at 06:21 UTC at a distance of 4,473,807 ± 155 km (2,779,895 ± 96 mi), or 11.7lunar distances, and a relative speed of 10.16 km/s (6.31 mi/s).[2]2014 YB35's next encounter with Earth will be in 2033, at a distance of approximately 3,330,000 km (2,070,000 mi).[2]
TheGoldstone Deep Space Communications Complex was scheduled to observe this object on 20 March 2015, at which time it was expected they could obtain coarse radar images and continuous wave spectra, which may help determine the asteroid's composition.[6] These observations showed a small companion less than 150 meters across orbiting the asteroid, with an unknown orbit.[3][4]
Thisminor planet wasnumbered by theMinor Planet Center on 25 September 2018 (M.P.C. 111778).[9] As of 2018, it has not beennamed.[1]
