Dropping Some Knowledge

XENA--Tentative name for the newly-discovered tenth
planet of our solar system, currently given the
designation 2003 UB313.

On July 30, 2005, it was offically announced that
astronomers at the California Institute of Technology
(ie. CalTech) discovered the planet, which is twice
the size of Pluto, which until now had been the
furthest planet from the sun in our solar system.
Xena's size helped in deciding the object was a true
planet and not an asteroid (sometimes called a minor
planet); this is not the case with the
previously-discovered Sedna, which is generally agreed
to be too small to be a true planet.

Xena was discovered in the Kuiper Belt after a five
year search by the CalTech team headed by Dr. Michael
Brown. It was photographed in 2003 by Brown, Chad
Trujillo of the Gemini Observatory and David
Rabinowitz of Yale University using a 48-inch
telescope at the Palomar Observatory. However, Xena
moves so slowly that movement wasn't detected until
this past January.

The Facts:
Size: 1,700 miles in diameter.
Distance from the Sun: 9 billion miles.
Orbit: 560 years.
Temperature: -240° C.
