No, this is not evidence of the mysterious ‘Planet X’ or Nibiru – but scientists think that there could be ‘at least two’ unknown planets beyond Pluto in our own solar system.
Astronomers suggest that there are ‘probably more’ planets yet to be found in a little-studied area at the ‘fringe’ or our solar system, known as the ‘inner Oort cloud’.
If confirmed, the new observation could change our view of the solar system forever.
The new theory comes from observations of space rocks beyond Neptune – which orbit at angles which don’t make sense unless there is something else there.
Astronomers have debated for decades whether there is an unknown, dark, trans-Plutonian planet in our solar system – but calculations made by scientists at the Complutense University of Madrid and the University of Cambridge suggest there could be more than one.
