(15874) 1996 TL66 (also written (15874) 1996 TL66) is a trans-Neptunian object (TNO) that resides in the scattered disc. 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.
