(523759) 2014 WK 509 , provisional designation 2014 WK 509 is a trans-Neptunian object in the scattered disc , located in the outermost regions of the Solar System . It was discovered on 14 September 2010, by Pan-STARRS at Haleakala Observatory on the island of Maui, Hawaii, in the United States. [1] The object's diameter has been estimated to measure approximately 600 kilometers. [3] [4]
Orbit and classification
2014 WK 509 belongs to the scattered disc population. It orbits the Sun at a distance of 40.1–61.6 AU once every 362 years and 6 months (132,399 days; semi-major axis of 50.8 AU). Its orbit has an eccentricity of 0.21 and an inclination of 15 ° with respect to the ecliptic . [2] The body's observation arc begins on 14 September 2011 at Haleakala, more than 3 years prior to its official first observation. [1] Its orbit still has a high uncertainty . [1] [2]
Numbering and naming
This minor planet was numbered by the Minor Planet Center on 25 September 2018 ( M.P.C. 111779 ). [5] As of 2018, it has not been named . [1]
Physical characteristics
Based on an absolute magnitude of 4.4, [2] and an assumed albedo of 0.09, the Johnston ' s archive estimates a mean-diameter of approximately 584 kilometers (363 mi) . [3]
As of 2018, no rotational lightcurve of this object has been obtained from photometric observations. The object's rotation period , pole and shape remain unknown. [2]
