(15874) 1996 TL66 (provisional designation 1996 TL66) is a trans-Neptunian object of the scattered disc orbiting in the outermost region of the Solar System.
The Spitzer Space Telescope has estimated this object to be about 575 kilometres (357 mi) in diameter, but 2012 estimates from the Herschel Space Observatory estimate the diameter as closer to 339 kilometres (211 mi). It is not a detached object, since its perihelion (closest approach to the Sun) is under the influence of Neptune. Light-curve-amplitude analysis suggests that it is a spheroid.
