2010 FX86, also written 2010 FX86, is a relatively bright trans-Neptunian object[2] with an absolute magnitude of about 4.65.[2][3][6]

It was first discovered on 17 March 2010, at Las Campanas Observatory in Chile, by S. S. Sheppard, A. Udalski and I. Soszynski. No earlier precovery images for it have been found. It is estimated to be about 520 kilometres (320 mi) in diameter,[6] with a rotation period of approximately 15.80 hours,[2] but as yet no detailed photometry has been taken to properly determine colour or albedo, or to better confirm its rotational lightcurve.
