28978 Ixion is a plutino (an object that has a 2:3 orbital resonance with Neptune). It is very likely to be a dwarf planet,<ref name="Brown-dplist" /><ref name="tancredi" /> although the IAU has not officially classified it as such. Light-curve-amplitude analysis shows only small deviations, which suggests that Ixion is a spheroid with small albedo spots and hence a dwarf planet.<ref name="SSDwarfs" /> It has a diameter of approximately {{safesubst:#invoke:val|main}}, making it about the fifth-largest plutino. It is moderately red in visible light and has a surface made of a mixture of tholin and water ice.

It was discovered on May 22, 2001 by the Cerro Tololo Inter-American Observatory (807).<ref name="MPEC2001-N01" /> It is named after Ixion, a figure from Greek mythology.
