mp|(15874) 1996 TL|66 (also written (15874) 1996 TL66) is a trans-Neptunian object that resides in the scattered disc.

Discovered

Discovered in 1996 by David C. Jewitt et al., it was the first object to be categorized as a scattered disk object (SDO), although mpl|(48639) 1995 TL|8, discovered a year earlier, was later recognised as a scattered disk object. It was one of the largest known Kuiper belt objects at the time of the discovery.

Orbit and Size

mp|1996 TL|66 orbits the Sun with a semi-major axis of 85.33 AU. Its diameter has been estimated at around 630 km by combined optical/thermal observations.cite web
