That's the astonishing claim contained in a new piece of research about Planet 9, a mysterious object thought to be hidden in an area of space beyond Neptune.
Alexandar Mustill , an astronomer from the Lund Observatory in Sweden, claimed Planet 9 was nicked from another star and then found itself locked in an eccentric orbit around the Sun.
The Sun first formed in a cluster of between 1,000 and 10,000 other stars, meaning it is likely that planets could easily travel between them.
"While the existence of Planet 9 remains unproven, we consider capture from one of the Sun's young brethren a plaAn "alien world" lurking at the edge of our solar system may have been stolen from another star.
