{{mp|2014 FC|69}} is a trans-Neptunian object orbiting in the scattered disc, approximately 533 kilometers in diameter. It was first observed on 25 March 2014, by astronomers at the Cerro Tololo Inter-American Observatory in Chile. Because of its great distance and short observation arc of 302 days, the object's orbit is too poorly determined to know whether it is in an orbital resonance with Neptune.

Distance

{{see also|List of most distant trans-Neptunian objects}}

Based on the best-fit (albeit uncertain) orbital solution, {{mp|2014 FC|69}} last came to perihelion around 1869, and is currently ({{asof|2016|2|lc=y}}) about 84.2 AU from the Sun. Other than long-period comets, it is the fifth-most-distant known large body in the Solar System (see table below).
