This plan of the outer solar system , produced by Gareth Williams of the Minor Planet Center housed at the CfA, shows the extraordinary orbit of 1996 TL66. The four light blue orbits denote Jupiter, Saturn, Uranus and Neptune. The swarm of orbits outside Neptune shows the extent of the "classical" Kuiper Belt at 50 AU. In contrast, the highly eccentric orbit of TL66 carries it as far as 130 AU at aphelion, suggesting that the outer solar system is populated at much larger distances than previously thought. TL66 was discovered (and is presently) near perihelion, at about 35 AU. The discovery reminds us that we still do not fully know the contents of our own solar system.
