Goddess of Discord Explained: Everything You Need to Know About Eris

Dive deep into Goddess of Discord Explained: Everything You Need to Know About Eris in our detailed breakdown.

When Roman writers adapted Hellenic myth, they recast Eris as Discordia. Roman poets, particularly Virgil in the Aeneid, placed Discordia among the terrifying figures lurking at the gates of the underworld, her viper-braided hair bound with blood-stained fillets. The Romans viewed Discordia less as a capricious force and more as a lethal civic disease, the terrifying impulse toward civil war that nearly extinguished Rome before the rise of Augustus.

Millennia later, the concept of discordant disruption migrated from epic poetry into planetary science. In January 2005, an observational team led by astronomer Mike Brown at the Palomar Observatory identified an object deep beyond Neptune, designated catalog number 2003 UB313. It was dense, frozen, and initially calculated to be larger than Pluto. The astronomical world fractured over whether to label it the solar system's tenth planet.

The name assigned to the icy sphere was deliberate. By forcing astronomers to formally define what a planet actually is, the object sowed absolute chaos across textbook publishing houses, museum exhibits, and academic departments. When the International Astronomical Union (IAU) voted in August 2006 to reclassify Pluto, Mike Brown accepted the poetic justice: the object was named Eris, and its newly discovered moon was christened Dysnomia, after the mythic daughter of strife who embodied lawlessness.
