1999 TR11, also written as 1999 TR11, is a plutino (a trans-Neptunian object in 2:3 mean-motion resonance with Neptune). It was discovered on October 9, 1999 by Scott Sheppard observing from Mauna Kea with the 2.2 University of Hawaii reflector. It has a perihelion at 29.775 AU and an aphelion at 49.647 AU, so it moves in a relatively eccentric orbit (0.25) and it crosses the orbit of Neptune the same as Pluto.
