2014 FC69 is a trans-Neptunian object that resides in the scattered disc. It was discovered on 25 March 2014. Because of its great distance and short observation arc of 302 days, 2014 FC69's orbit is too poorly determined to know whether it is in an orbital resonance with Neptune.
Distance
Based on the best-fit (albeit uncertain) orbital solution, 2014 FC69 last came to perihelion around 1869,[1] and is currently about 84.0 AU from the Sun. Other than long-period comets, it is currently about the fifth-most-distant known large body in the Solar System, after V774104 (~103 AU), Eris and Dysnomia (96.3 AU), 2007 OR10 (87.4 AU), and Sedna (85.9 AU).
