Orbit and classification. belongs to the Apollo asteroids, which cross the orbit of Earth. Apollo's are the largest group of near-Earth objects with nearly 10 thousand known members. It orbits the Sun at a distance of 0.84–1.73 AU once every 18 months (531 days; semi-major axis of 1.28 AU). Its orbit has an eccentricity of 0.35 and an inclination of 8° with respect to the ecliptic. With an aphelion of 1.73 AU, it is also a Mars-crosser, as it crosses the orbit of the Red Planet at 1.66 AU. The body's observation  arc begins with its first recorded observation by Pan-STARRS on 20 January 2018. Close approaches. The object has a low minimum orbital intersection distance with Earth of , which corresponds to 0.078 lunar distances (LD). On 8 February 2034, it will approach Earth to a distance of or 8.2 LD. 2018 flyby. On 6 February 2018, it passed at a nominal distance of from Earth (0.49 LD). One hour earlier, it passed the Moon at . Physical characteristics. The body's physical parameter remain largely unknown. Based on a generic magnitude-to-diameter conversion, and for an absolute magnitude of 26.541 , the asteroid measures 15 and 40 meters in diameter, assuming a carbonaceous and stony albedo of 0.057 and 0.20, respectively. No rotational lightcurve has been obtained from photometric observations, and no rotation period, shape or pole has been determined. Naming. As of 2018, this minor planet has not been numbered or named.
