2014 YB₃₅ (also written 2014 YB35) is a near-Earth asteroid discovered by the Catalina Sky Survey on 27 December 2014. It is approximately 520 metres (1,710 ft) in diameter.^[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 11.7 lunar distances, and a relative speed of 10.16 km/s (6.31 mi/s).^[2] The Goldstone Observatory 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.^[1] These observations showed a small companion less than 150 meters across orbiting the asteroid, with an unknown orbit.^[3]^[4]

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]
