1994 TB
Discovered 1994 Oct. 2 at Mauna Kea. A compromise circular orbit is given.
The observations can be satisfied equally well by a perihelic Neptune 2:3
orbit (a = 39.3 AU, e = 0.22, minimum distance 15 AU from Neptune) or by an
aphelic Neptune 1:1 librating orbit (a = 30.0 AU, e = 0.07, minimum distance
25 AU from Neptune).
