    (86039) 1999 NC43, provisionally known as 1999 NC43, is a near-Earth asteroid and potentially hazardous object.[2] It was discovered on 14 July 1999 by Lincoln Near-Earth Asteroid Research (LINEAR) at an apparent magnitude of 18 using a 1.0-meter (39 in) reflecting telescope.[1] It has a diameter of 2.2 kilometers (1.4 mi).[2] 1999 NC43 is suspected to be related to the Chelyabinsk meteor from 15 February 2013.[3][4]

    1999 NC43 has a well-determined orbit with an uncertainty of 0.[2] It makes close approaches to Venus, Earth, and Mars.[5] Its most notable close approach to Earth will be on 14 February 2173 at a distance of 0.03361 AU (5,028,000 km; 3,124,000 mi).[5]
