, prov. designation:, is a trans-Neptunian object from the outermost region of the Solar System. It was discovered on 9 July 2013, by astronomers with the Pan-STARRS survey at Haleakala Observatory, Hawaii, United States. It is a dwarf planet candidate, as it measures approximately 350km (220miles) in diameter.
orbits the Sun at a distance of 31.3–55.1 AU once every 283 years and 9 months (103,645 days; semi-major axis of 43.18 AU). Its orbit has an eccentricity of 0.28 and an inclination of 19° with respect to the ecliptic. The body's observation arc begins at Haleakalā with a precovery taken in August 2010, nearly 3 years prior to its official discovery observation.
This minor planet was numbered by the Minor Planet Center on 5 October 2017 and received the number in the minor planet catalog . As of 2021, it has not been named.
According to American astronomer Michael Brown and the Johnston's archive, measures 344 and 352 kilometers in diameter based on an assumed albedo of 0.08 and 0.09, respectively. On his website, Brown lists this object as a "possible" dwarf planet (200–400 km), which is the category with the lowest certainty in his 5-class taxonomic system. As of 2021, no spectral type and color indices, nor a rotational lightcurve have been obtained from spectroscopic and photometric observations. The body's color, rotation period, pole and shape remain unknown.
