Eris (minor-planet designation: 136199 Eris) is the most massive and second-largest known dwarf planet in the Solar System. [22] It is a trans-Neptunian object (TNO) in the scattered disk and has a high-eccentricity orbit. Eris was discovered in January 2005 by a Palomar Observatory–based team led by Mike Brown and verified later that year.

They were not generally thought to be planets on their discovery, and planetary symbols had in any case mostly fallen out of use among astronomers by then. Denis Moskowitz, a software engineer in Massachusetts, [94] proposed astronomical symbols for the dwarf planets Quaoar, Sedna, Orcus, Haumea, Eris, Makemake, and Gonggong.

Dwarf planet Eris, similar in size to its better-known cosmic cousin Pluto, has remained an enigma since being discovered in 2005 lurking in the solar system's far reaches. While Pluto was ...
The number of dwarf planets in the Solar System is unknown. Estimates have run as high as 200 in the Kuiper belt [1] and over 10,000 in the region beyond. [2] However, consideration of the surprisingly low densities of many large trans-Neptunian objects, as well as spectroscopic analysis of their surfaces, suggests that the number of dwarf planets may be much lower, perhaps only nine among ...
