The newly discovered dwarf planet numbered 2003 UB313 has now been officially named as Eris and its satellite has been named as Dysnomia.
Eris’ discoverer, Michael Brown of the California Institute of Technology, said the name was an obvious choice, calling it “too perfect to resist.”
In mythology, Eris caused a quarrel among goddesses that sparked the Trojan War. In real life, Eris forced scientists to define a planet that eventually led to Pluto getting the boot. Soon after Pluto’s dismissal from the planet club, hundreds of scientists circulated a petition protesting the decision.
Eris’ moon also received a formal name: Dysnomia, the daughter of Eris known as the spirit of lawlessness.
Eris, which measures about 70 miles wider than Pluto, is the farthest known object in the solar system at 9 billion miles away from sun. It is also the third brightest object located in the Kuiper belt, a disc of icy debris beyond the orbit of Neptune.
Meanwhile the newly downgraded to dwarf planet Pluto has been given a number – 134340
Pluto has been given a new name to reflect its new status as a dwarf planet.
On Sept. 7, the former 9th planet was assigned the asteroid number 134340 by the Minor Planet Center (MPC), the official organization responsible for collecting data about asteroids and cometsin our solar system.
