For a period of time, the object became known to the wider public as Xena. "Xena" was an informal name used internally by the discovery team, inspired by the title character of the television series Xena: Warrior Princess. The discovery team had reportedly saved the nickname "Xena" for the first body they discovered that was larger than Pluto.
Observations made by New Horizons subsequently found Pluto to be marginally larger than the object, which was ultimately named Eris. The object's nickname "Xena" was used in the press. New Scientist magazine polled the public on their preferred final name for the so-called tenth planet; "Xena" ranked number 4. [59]

It is about half the diameter and an eighth the mass of Pluto, a dwarf planet that resides in a frigid region of the outer Solar System called the Kuiper Belt, beyond the most distant planet Neptune.

The last major TNO, Eris, was at first considered by him, his team, NASA, and many others to be the tenth planet, [4] but the International Astronomical Union assigned it to the new classificatory category of dwarf planet.

Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. It is the ninth-largest and tenth-most-massive known object to directly orbit the Sun. It is the largest known trans-Neptunian object by volume, by a small margin, but is less massive than Eris.
