Scientists find planet that behaves like mysterious ‘Planet Nine’

Nasa's Hubble Space Telescope has spotted a world that behaves like the long-sought and still mysterious and unproven "Planet Nine".

For years, some researchers have been proposing the there is an undiscovered planet hovering at the edge of our solar system. While no such world has been directly observed, scientists have suggested that it would explain the unusual behaviour of other objects in the distant reaches of our planetary neighbourhood.

Now the Hubble Space Telescope has spotted a planet 336 light years away that could offer clues about Planet Nine. The planet, known as HD106906 b, may have experienced something of the same process that left our own hypothetical Planet Nine lingering at the reaches of our solar system.
