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.
Eris is NOT the largest dwarf planet in our solar system. It was initially thought to be so, but in November 2010, a team of astronomers led by Bruno Sicardy observed Eris occult a star and determined it is marginally smaller than Pluto though 27 percent more massive.he discovery of Eris was so important because it was a celestial body larger than Pluto, which forced astronomers to consider, for the first time in history, what the definition of a planet truly is.
