While most of us grew up safe in the knowledge there were nine planets orbiting our sun, recent developments have left things more confused, after scientists decreed Pluto was in fact only a dwarf planet.
As if this wasn't complicated enough, a Cambridge scientist has now suggested there could in fact be as many as 10 or 11 planets in the Milky Way, after his computer analysis hinted at the existence of unknown mystery planets at the far edges of our solar system.
The motions of the extreme trans-Neptunian objects suggest that there is an unknown planet in the confines of the Solar System
In January, astronomers in California predicted the existence of a ninth planet after discovering 13 objects in the Kuiper Belt – an area beyond Neptune – were all moving together as if 'lassooed' by the gravity of a huge object.
Now, working with Spanish astronomers Carlos and Raúl de la Fuente Marcos, Dr Sverre J. Aarseth from Cambridge University's Institute of Astronomy, discovered the paths of the dwarf planets are not as stable as first thought, meaning they could be falling under the influence of more planets further out.
