Sub-kilometer asteroid and near-Earth object May 2019 yes (529366) 2009 WM 1 #FFC2E0 CSS Catalina Stn. 17 November 2009 (529366) 2009 WM 1 NEO Apollo PHA 27 April 2019 (JD 2458600.5) 0 8.99 yr (3,283 d) 1.3798 AU 0.9810 AU 1.1804 AU 0.1689 1.28 yr (468 d) 144.70° 0.7685 ms / day 25.768° 240.27° 162.62° 0.0001 AU (0.039 LD) 280 m (est.) 2.9 10 kg 20.4 (529366) 2009 WM 1 is a sub-kilometer asteroid and near-Earth object of the Apollo group, approximately 280 m ft off us in diameter. After its discovery by the Catalina Sky Survey at the Catalina Station in Arizona, United States, this potentially hazardous asteroid was briefly listed at a Torino Scale of 1 and a cumulative Palermo Scale of −0.87. It was removed from the Sentry Risk Table on 26 June 2013. Numbering and naming This minor planet was numbered by the Minor Planet Center on 18 May 2019 (M.P.C. 114667). As of 2019, it has not been named. Orbit and classification 2009 WM 1 orbits the Sun at a distance of 0.98–1.38 AU once every 15 months (468 days; semi-major axis of 1.18 AU). Its orbit has an eccentricity of 0.17 and an inclination of 26° with respect to the ecliptic. Even though 2009 WM 1 has an Earth MOID of 0.00009 AU km mi on off, the orbit and future close approaches are well determined with an orbital uncertainty of 1. On 23 November 2059, 2009 WM 1 will pass 0.0046 AU km mi on on from Earth. On 23 November 2199, it will make another close approach at a distance of 0.0005 AU km mi on on to 0.069 AU, but since it is a close approach and the exact distance in uncertain, future close approaches after 2199 are uncertain. 2014 passage The 21 May 2014 Earth close approach of 0.3622 AU km mi on off should allow a refinement to the orbit. From 7 May 2014 until 2 June 2014 the asteroid will be brighter than apparent magnitude 20. The asteroid came to opposition on 18 May 2014 when it was up all night.
