About Eris
Eris is a dwarf planet located in the outer regions of the solar system. It is one of the largest known dwarf planets and was discovered in 2005. Eris is named after the Greek goddess of strife and discord, fitting for a planet that played a significant role in the debate surrounding the definition of a planet.
Discovery and Characteristics
Eris was discovered by a team of astronomers led by Mike Brown, Chad Trujillo, and David Rabinowitz. It is located in the scattered disc, a distant region of the solar system beyond the orbit of Neptune. Eris is about 27% more massive than Pluto and has a highly elliptical orbit that takes it from about 38 to 98 astronomical units from the sun.
Composition and Surface
The composition of Eris is believed to be similar to that of Pluto, with a rocky core surrounded by a mantle of water ice. The surface of Eris is extremely cold, with temperatures reaching as low as -240 degrees Celsius. Eris has a tenuous atmosphere composed mostly of methane gas.
Debate Over Planetary Status
When Eris was first discovered, it was initially thought to be larger than Pluto. This led to a debate within the scientific community about the definition of a planet. In 2006, the International Astronomical Union redefined the criteria for a celestial body to be classified as a planet, leading to the demotion of Pluto to dwarf planet status and the classification of Eris as a dwarf planet.
Future Exploration
Due to its distance from Earth and the outer regions of the solar system, Eris has not been explored up close by any spacecraft. However, with advances in space exploration technology, there may be future missions to study Eris and other distant objects in the outer solar system.
