Eris is a dwarf planet, because it is sufficiently massive that it's formed into a spheroid due to its own gravity, but it has not cleared its orbital path, as it would need to in order to be considered a planet.
Eris is the largest known object in the Kuiper Belt.

∙ 12y agoEris is the largest known dwarf planet in the Solar System, and the ninth-largest body known to orbit the Sun directly. It is approximately 2,500 kilometres in diameter and 27% more massive than Pluto. It is named after the Greek goddess of strife and discord.

∙ 8y agoEris is a dwarf planet. It is the celestial object that made astronomers write a definition for what is a planet. It appears to be larger and denser than Pluto so astronomers speculate that it is made of mostly rocky materials and has a frozen methane surface. We should learn more in July of 2015 because New Horizons, a space probe, will be flying past Pluto.

∙ 14y agoIt's not likely that there are any (solar) planets waiting to be discovered out there, though it can't be definitely ruled out. With dwarf planets it gets a little more complicated. Currently Eris is the furthest known dwarf planet, and in fact one of the most distant known objects in the solar system. However, Sedna is probably a dwarf planet (the question is whether it's in hydrostatic equilibrium or not), and gets considerably further away from the sun than Eris ever does (right now Sedna is nearly as close to the sun as it ever gets, while Eris is nearly as far away from the sun as it ever gets, so at the moment ... and for the next hundred years or so ... Eris is a bit more distant). Sedna has a semimajor axis of around 500 AU (Eris: 70 AU) and an aphelion of nearly 1000 AU (Eris: 100 AU), so on average it's quite a bit further out.

∙ 8y agoEris is considered a dwarf planet rather than a planet because it can not been able to "clear the neighborhood" of other objects.

∙ 15y agomainly because most people think that ummm there should only be 8 planets but really i dont think it should be concidered as a dwarf planet but a real planet because it is really big actually

∙ 8y agoEris is a dwarf planet. It is not yet certain if it is larger than Pluto or not. It has surface methane. It is denser than Pluto so scientists feel it has more rocky particulates.
