Eris, the largest dwarf planet. Eris is a dwarf planet that lies at the outer reaches of our solar system. It was discovered in 2005 by professional astronomers who were examining images taken at California's Palomar Observatory two years previously.
If you mean the dwarf planet 136199 Eris then I can answer to the question. Eris has a rocky core and icy mantle like other large trans-Neptunian objects like 20000 Varuna, 28978 Ixion, 38628 Huya, 50000 Quaoar, 90377 Sedna, 90482 Orcus, 134340 Pluto, 136108 Haumea, 136472 Makemake and 225088 (2007 OR10) for example.
