Ihlabathi elibangela abaphengululi belanga bagqibe ukuba yintoni iplanethi, nesizathu sokuba iPluto iphinde yahlukaniswa.
I-Eris yafunyanwa ngo-2005. Its highly eccentric, steeply inclined orbit takes it from about 38 to 98 au from the Sun, and one orbit takes about 560 years.
Incinci kakhulu kunePluto. Ukufumana isiqu esingaphezulu kweNeptune kwatyhala i-International Astronomical Union ukuba ichaza igama leplanethi ngo-2006. Inyanga yayo iDysnomia yayenza ukuba ibe lula ukulinganisa ubunzima bayo.
