Yes. "Xena" was a provisional name given to Eris.
Xena was the provisional name for Eris. So yes
Before it was officially named, Eris was nicknamed Xena.
UB313 was the unofficial name for Eris the largest known dwarf planet. Xena was used by the discovery team to denote UB313. So yes - Xena is UB313 is Eris
No. scientists have found dozens of planets about the same size as Eris and Pluto. I think they should just be Dwarf planets.
The dwarf planet "Eris" was originally nicknamed "Xena". So, Xena was the name of something that was thought to be a new planet, but is now classified as only a dwarf planet, like Pluto.
Astronomers searching for additional planets beyond Neptune had reserved the name "Xena" for the "warrior princess" of the 1990's TV show. When they discovered a planet larger than Pluto, they assigned that as a provisional name. After the IAU demoted Pluto from "planet" to "dwarf planet", the object tentatively named "Xena" received a permanent name of "Eris". Eris is believed to have one moon.
The dwarf planets in our solar system are Pluto, Eris, Haumea, Makemake, and Ceres. These objects are similar to planets in size but have not cleared their orbits of other debris, which is one of the criteria for being classified as a planet.
Ceres and Eris are not planets; they are dwarf planets. Eris is much larger than Ceres.
No, they are two different "dwarf Planets".
Xena and Gabrielle were Xena : Warrior Princesscharacters played by Lucy Lawless and Renée O'Connor. These names were not adopted by the International Astronomical Union for the dwarf planet "2003UB313" and its moon. In August, 2006, the IAU chose "Eris" (Grek goddess of discord) and "Dysnomia" (Greek for 'lawlessness') as the names of the objects. The objects were photographed in 2003 and identified as solar-system objects in January, 2005. During the period between discovery and naming, the Palomar Observatory team (Mike Brown, Chad Trujillo, and David Rabinowitz) had used the TV names as interim designations for the faraway planetoids.
The three celestial bodies redefined as dwarf planets by the International Astronomical Union (IAU) are Pluto, Eris, and Haumea. They are recognized as dwarf planets due to their size, shape, and inability to clear their orbits of other debris.
You probably mean "Xena". When you say Xena, it sounds like Zena. It is now called "Eris" and is classed as a "dwarf planet".
