Eris (minor-planet designation: 136199 Eris), sab se jaada garrhu aur duusra sab se barraa bauna grah, Saur Mandal me hae. [6] Ii ek trans-Neptunian object (TNO) hae aur iske high-eccentricity orbit hae. Eris ke January 2005 me Palomar Observatory–based team, jike Mike Brown lead karis rahaa, paaais rahaa aur iske ek saal baad fir se verify karaa gais rahaa. Iska naam September 2006 me, GrecoTemplate:En dashRoman deota ke baad rakkhaa gais rahaa. Suraj ke parikrama kare waala chij me se, Eris 9th sab se garrhu hae, aur agar sab chaand ke lewa jaae tan ii 16th hae. Ii saur mandal ke sab se barraa chij hae jiske koi spacecraft visit nai karis hae. Eris ke diameter 2,326 ± 12 kilometres (1,445 ± 7 mi) hae; iske wajan dunia ke 0.28% hae aur Yamgrah se 27% jaada hae, jabki Yamgrah, by volume, thorraa barraa hae. Duuno Eris aur Yamgrah kesurface area Russia nai to South America ke baraabar hae.
