New Planet Spotted... Hopefully Will Have a "P" Name

From Yahoo! News:

Scientists at a Japanese university said Thursday they believed another planet up to two-thirds the size of the Earth was orbiting in the far reaches of the solar system.

The researchers at Kobe University in western Japan said calculations using computer simulations led them to conclude it was only a matter of time before the mysterious "Planet X" was found.

"Because of the very cold temperature, its surface would be covered with ice, icy ammonia and methane," Kobe University professor Tadashi Mukai, the lead researcher, told AFP.
"If research is conducted on a wide scale, the planet is likely to be discovered in less than 10 years," it said.

Planet X -- so called by scientists as it is yet unfound -- would have an oblong elliptical solar orbit and circle the sun every thousand years, the team said, estimating its radius was 15 to 26 billion kilometres.

The study comes two years after school textbooks had to be rewritten when Pluto was booted out of the list of planets.
