It was discovered on 18 November 2000, by astronomers with the LINEAR program at the Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico, in the United States.[1] The dark Jovian asteroid belongs the 100 largest Jupiter trojans and has a rotation period of 23.3 hours. It has not been named since its numbering in November 2001.[24] Orbit and classification{{mp|2000 WX|182}} is a Jupiter trojan in a 1:1 orbital resonance with Jupiter. It is located in the trailering Trojan camp at the Gas Giant's {{L5}} Lagrangian point, 60° behind its orbit {{cross reference|(see Trojans in astronomy)}}.[5] It is also a non-family asteroid of the Jovian background population.[6] It orbits the Sun at a distance of 4.9–5.7 AU once every 12 years and 1 month (4,419 days; semi-major axis of 5.27 AU). Its orbit has an eccentricity of 0.08 and an inclination of 30° with respect to the ecliptic.The body's observation arc begins with a precovery published by the Digitized Sky Survey and taken at Palomar Observatory in January 1955, more than 45 years prior to its official discovery observation at Socorro.[1] Numbering and namingThis minor planet was numbered by the Minor Planet Center on 30 November 2001 ({{small|M.P.C. 44050}}).[24] As of 2018, it has not been named.[1] Physical characteristics{{mp|2000 WX|182}} is an assumed, carbonaceous C-type asteroid.[13] Most Jupiter trojans are D-types, with the reminder being mostly C and P-type asteroids. It has a typical V–I color index of 0.95 and a BR color of 1.23 (also see table below).[13]Rotation periodIn November 2013, a rotational lightcurve of {{mp|2000 WX|182}} was obtained from eleven nights of photometric observations by Robert Stephens at the Center for Solar System Studies in Landers, California. Lightcurve analysis gave a rotation period of {{val|23.34|0.01}} hours with a brightness amplitude of 0.19 magnitude ({{small|U=3-}}).[10][13]{{efn|name=lightcurve-plots-CS3}} Diameter and albedoAccording to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer and the Japanese Akari satellite, {{mp|2000 WX|182}} measures 48.02 and 51.63 kilometers in diameter and its surface has an albedo of 0.070 and 0.080, respectively.[8][9] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for a carbonaceous asteroid of 0.057 and calculates a diameter of 50.77 kilometers based on an absolute magnitude of 10.2.[13] {{Largest Jupiter trojans}}Notes{{notelist|refs={{efn|name=lightcurve-plots-CS3|1=Lightcurve plots of (32496) 2000 WX182 from Nov 2013 by Robert Stephens at the Center for Solar System Studies {{Obscode|U81}}.
