2015 FG415

 is a trans-Neptunian object from the scattered disc, located in the outermost region of the Solar System. It was discovered on 17 March 2015, by American astronomer Scott Sheppard at the Mauna Kea Observatories, Hawaii, and received the provisional designation. , it is the 9th-most-distant object from the Sun at 87.2 AU and measures approximately 280 km in diameter.

Orbit and classification
orbits the Sun at a distance of 36.0–91.9 AU once every 511 years and 7 months (186,866 days; semi-major axis of 63.97 AU). Its orbit has an eccentricity of 0.44 and an inclination of 5° with respect to the ecliptic.

It is classified as a scattered disc object, or "near-scattered" in the classification of the Deep Ecliptic Survey, that still interacts gravitationally with Neptune (30.1 AU) due to its relatively low perihelion of 36.0 AU, contrary to the extended-scattered/detached objects and sednoids which never approach Neptune as close.

Most distant objects from the Sun
will come to perihelion in 2209, moving towards the Sun, currently located at a distance of 87.2 AU, which makes it the 9th-most-distant known minor planet in the Solar System, after, , , , , , , and Gonggong, (also see ).

Physical characteristics
Based on a generic magnitude-to-diameter conversion, measures approximately 280 km in diameter, for an assumed albedo of 0.9 with an absolute magnitude of 6.0. Mike Brown considers this object to be a weak dwarf planet candidate ("possibly") estimating a mean-diameter of 277 km., no rotational lightcurve for this object has been obtained from photometric observations. The body's rotation period, pole and shape remain unknown.
