 As of 2008 there were approximately forty known TNOs, most notably , and , that are currently closer to the Sun than Eris even though their semimajor axis is larger than that of Eris (67.8 AU).Eris's orbit is highly eccentric, and brings Eris to within 37.9 AU of the Sun, a typical perihelion for scattered objects.This is within the orbit of Pluto, but still safe from direct interaction with Neptune (~37 AU).
