Eris was first photographed in October 2003, and was officially labelled UB2003. It wasn't until January 2005 that an ecstatic Mike Brown realised he had a big planet on his hands and unofficially called the planet Xena and her moon Gabrielle. The nickname had been taken from the hit TV series 'Xena the Warrior Princess', and the name Gabrielle from her sidekick in the show.
Eris is also known as the asteroid of discord. This sign helps you understand yourself and know more about your strife, needs, energy, quarrels and discord. Along with the sun sign and moon sign, the Eris sign also helps you understand yourself better. Eris in Greek means "Discordia". This has given rise to a most unconventional kind of astrology. Eris is known to be a troublemaker and responsible for a lot of problems. In general it is associated with hardships, quarrels, fights, battles, jealousy, rivalry and revenge. But there are positive effects too like energy, resourcefulness, ability to have a clear mind in emergencies and the wish to work for happiness. This is a very slow moving planet and the effects will be seen only in relation with other planets it aspects.
The solar system's newest planet, formerly known as 2003 UB313 or Xena, now has an official name, Eris, and the name is pronounced EE-ris. Named after the goddess of discord, Eris held true to her name, creating such controversy about her planetary presence that the veteran planet Pluto was demoted to dwarf planet status by astronomers as they grappled with naming the new planet.
Breathless scientists announced her discovery as the Solar System's 10th planet on July 29, 2005, and promptly nicknamed it Xena, after the warrior princess from TV series of the same name. Mercury was retrograde at that time, so you just knew something would get snarled up and it did.
While the name, Xena, captured the media's fascination, it was only intended to be an interim nickname according to Michael Brown (no relation to your humble webmaster), a member of the team that made the discovery using telescopes at the Palomar Observatory, outside San Diego, California. The team has discovered several new planets in recent years, including Quaoar, Sedna, and Orcus. Eris was originally identified on October 31, 2003, but the announcement was held back for almost two years while astronomers did further studies.
