Astronomers in France have managed to narrow down the area in which the new planet could be located.
Nobody knows exactly where it is, how big it is or if it even exists at all, but when researchers at the California Institute of Technology revealed earlier this year that the existence of a ninth planet in our solar system was a very real possibility, the hunt for this enigmatic new world began in earnest.
Scientists believe that if it does exist, the new planet is likely to be around ten times the mass of the Earth and could take up to 20,000 years to complete a single orbit around the sun. It is also likely to be twenty times further out from the sun than the current furthermost planet, Neptune.
