This Greek goddess's name was chosen for the dwarf planet responsible for discord on Pluto's classification amongst astronomers.

The reason why the Greek goddess's name chosen for the dwarf planet responsible for discord on Pluto's classification amongst astronomers is Eris is because Eris is the goddess of discord and strife in Greek mythology. In 2005, astronomers discovered a dwarf planet beyond Pluto and named it Eris due to its ability to cause disagreement and controversy about Pluto's classification as a planet. This name reflected the discord and disagreement among astronomers regarding the criteria for categorizing celestial bodies, resulting in the reclassification of Pluto as a dwarf planet.
