Sub-kilometer asteroid on an eccentric orbit August 2021 yes (585310) 2017 YZ 1 #FFC2E0 Mount Lemmon Srvy. Mount Lemon Obs. 20 December 2017 (585310) 2017 YZ 1 NEOPHAApollo 1 July 2021 (JD 2459396.5) 0 8.78 (3,206 days) 1.7715 AU 0.8830 AU 1.3272 AU 0.3347 1.53 yr (558 d) 43.773° 0.6445975 ms / day 20.875° 277.75° 298.39° 0.00012 AU LD on on 0.26 km 20.43 (585310) 2017 YZ 1 is a sub-kilometer asteroid on an eccentric orbit, classified as a near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 250 m ft off 1 us in diameter. It was first observed on 20 December 2017, by astronomers with the Mount Lemmon Survey at Mount Lemmon Observatory near Tucson, Arizona, in the United States. On 29 January 2018, it passed Earth at 125 lunar distances. Orbit and classification 2017 YZ 1 is a member of the Apollo asteroids, which cross the orbit of Earth. Apollos are the largest group of near-Earth objects with nearly 10 thousand known objects. It orbits the Sun at a distance of 0.88–1.77 AU once every 18 months (558 days; semi-major axis of 1.33 AU). Its orbit has an eccentricity of 0.33 and an inclination of 21° with respect to the ecliptic. Risk assessment The 9 January 2018 solution with a 15-day observation arc was listed at Torino scale 1 with a 1:21,000 chance of impacting Earth on 30 June 2047. By 9 January 2018, the geocentric 30 June 2047 uncertainty region had shrunk to ±50 million km. With a longer 20 day observation arc, it dropped to Torino scale 0 and had a 1:670,000 chance of impacting Earth on 30 June 2047. On 18 January 2018 it was removed from the Sentry Risk Table. With a 28-day observation arc, the nominal solution suggests it will be about 0.25 AU km from Earth on 30 June 2047. The 3-sigma uncertainty in the 2047 close approach distance is about ±13 million km. Numbering and naming This minor planet was numbered by the Minor Planet Center on 10 August 2021, receiving the number 585310 585310 in the minor planet catalog (M.P.C. 133609). 2025, it has not been named.
