(47171) 1999 TC36 (also written: (47171) 1999 TC36) is a system comprising three trans-Neptunian objects (TNOs). It was discovered in 1999 by Eric P. Rubenstein and Louis-Gregory Strolger during an observing run at Kitt Peak National Observatory (KPNO). Dr. Rubenstein was searching images taken by Dr. Strolger as part of the Low-Z Supernova Search program. It is classified as a plutino with a 2:3 mean motion resonance with Neptune, and, currently only being 30.7 AU from the Sun, is among the brighter TNOs.

(47171) 1999 TC36 is a triple system consisting of a central primary, which is itself a binary, and a small moon (component B). The combined observations by the infrared Spitzer Space Telescope, Herschel Space Telescope and the Hubble Space Telescope (HST) make it possible to estimate the sizes of the components and consequently provide the range of possible values for the objects’ bulk density. The single-body diameter (effective system size) of 1999 TC36 is currently estimated at 393.1 +25.2
