Eris, Makemake and Haumea / Eris, Makemake y Haumea
Eris, Makemake and Haumea are dwarf planets located behind Pluto, in areas of the solar system known as scattered disk and Kuiper Belt. They are known as dwarf planets likewise Ceres and Pluto, but unlike these two have not been seen in sufficient detail to show that completely fit the definition of planets. Eris has a mass larger than Pluto and Makemake and Haumea are still under investigation. Besides these three bodies fall into a new category called "plutinos" or "trans-" by many. Although the IAU does not specify a specific name, are often referred to by the abbreviation TNO (Trans neptunian object). This category of objects similar to Pluto only applies to dwarf planets if they are trans-Neptunian objects and their periods, inclinations and eccentricity are similar to those of Pluto and therefore are on the scattered Disk, the Kuiper Belt or the Oort Cloud. In addition, there are a few bodies who are candidates for recognition as "dwarf planets"
