(523683) 2014 CP23 (provisional designation 2014 CP23) is a trans-Neptunian object from the scattered disc located in the outermost region of the Solar System It was discovered on 29 October 2011, by astronomers with the Pan-STARRS survey at Haleakala Observatory, Hawaii, United States. [1] The dwarf planet candidate measures approximately 267 kilometers (170 miles) in diameter.
2014 CP23 orbits the Sun at a distance of 38.1–66.5 AU once every 378 years and 5 months (138,225 days; semi-major axis of 52.32 AU). Its orbit has an eccentricity of 0.27 and an inclination of 29° with respect to the ecliptic. [2] It is a scattered-disc object on a moderately eccentric orbit that never comes closer than 8 AU to the orbit of Neptune.
The body's observation arc begins with a precovery taken by the Sloan Digital Sky Survey in January 2003, or more than 8 years prior to its official discovery observation at Haleakala Observatory. [1]
This minor planet was numbered by the Minor Planet Center on 25 September 2018 and received the number 523683 in the minor planet catalog ( M.P.C. 111779). [5] As of 2018, it has not been named. [1]
According to American astronomer Michael Brown and the Johnston's archive, 2014 CP23 measures 266 and 267 kilometers in diameter based on an assumed albedo of 0.08 and 0.09, respectively. [3] [4] 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. [4] As of 2018, 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. [2] [6]
