First a new zodiac sign, now a new planet? The wonders of the cosmos never cease.

As Jesus Diaz at Gizmodo reports, University of Louisiana astrophysicists John Matese and Daniel Whitmire say there's a planet four times larger than Jupiter lurking in our solar system:
According to them, this colossus is hiding in the Oort Cloud -- the asteroid beehive that forms the outer shell of our home system, one light-year in radius.
For now the planet (or hypothetical planet) has been dubbed Tyche. The Independent has more details about its existence (or hypothetical existence). Here's what we know:
If it's real, Tyche probably consists of helium and hydrogen.
It's not hiding, exactly, it's just really far away. The astrophysicists reckon Tyche is 15,000 astronomical units from Earth. (For perspective, the Earth is one AU from the sun.)
Whitmire and Matese believe Tyche's atmosphere would be much like Jupiter's and that the super-planet would have bands, clouds and moons.
If it does exist, it may get renamed, because the International Astronomical Union has final say over planet names. In Greek mythology, Tyche (ty-kee) was a goddess who determined the fortune and prosperity of cities.
Data from NASA's outer space Wide-Field Infrared Survey Explorer, better known as WISE, will be the key to learning if Tyche exists or not. A first round of data from WISE will become available in April, and Matese and Whitmire say they expect to prove Tyche's existence within two years of studying data gleaned from the explorer's sky survey mission.

Interesting if this pans out to be true. I wonder if it will appear as a 'star' anytime soon.
