US astronomers say they may have discovered a new planet in the solar system about 10 times bigger than earth. The object is named planet 9. Jonathan Amos has more.

“The idea that there might be a so-called planet-x moving in the distant reaches of the solar system has been dated for more than 100 years. It's fallen in and out of vogue, the latest claim is based on the analysis of the movements of objects in the band of icy material orbiting more than 3 billion miles away, known as the Kuiper belt. The only way these alignments can be explained, said the Cal tech team, is for an object 10 times as massive as the earth is out there somewhere moving perhaps 20 times as far away as Neptune, the current most distant planet.
