10th Planet Discovered
Astronomers from the Palomer Observatory, the Gemini Observatory and Yale University, have discovered the 10th planet in the solar system. The planet is located beyond the orbit of Pluto -- just over twice the distance from the Sun than Pluto, which puts it smack in the Kuiper Belt. The planet is currently the third brightest object in the Kuiper Belt. Astronomers are estimating that the planet is most likely larger than Pluto, based on the amount of sunlight it is reflecting. The temporary name of the planet is 2003 UB313. The IAU is determining the permanent name for the planet.
The announcement of the planet, follows the announcement of the discovery of another large Kuiper Belt object -- currently known as 2003 EL61. 2003 EL61 appears to be as large as Sedna -- although it appears that the verdict is still out on whether Sedna, Quaoar and Orcus (other Kuiper Belt objects) are really planets.
