In the astronomy of the Solar System, is a sub-kilometer asteroid, classified as near-Earth object that belongs to the Apollo group. It measures approximately 40–90 meters.[1] During a close approach to Earth, it was first observed 25 January 2017, by the ATLAS survey at Haleakala Observatory, Hawaii, United States.
has a low-eccentricity orbit with a semi-major axis only slightly larger than that of Earth. It orbits the Sun at a distance of 1.008–1.023 AU once every 1.02 years (374 days). Its orbit has an eccentricity of 0.01 and an inclination of 11° with respect to the ecliptic. It has an Earth minimum orbital intersection distance of 0.007abbr=onNaNabbr=on, which corresponds to 2.7 lunar distances. The body is too small to be classified as a potentially hazardous asteroid.
On 23 July 2017, it passed by within 3.15 lunar distances.[2] Seen from the Earth it passed straight north to south from Draco south into Scorpio. With its 1.023 year orbit it has a synodic period of 43 years with the earth, so it will flyby the Earth every 43 years or so. JPL Small-Body Database's simulator show the previous flyby in July 1973 and next one will be in July 2061.
