Planet 9 ‘stolen’ by our Sun
Planet 9 ‘stolen’ by our Sun
June 20, 2016
Scientists in Sweden have said it’s highly likely that Planet 9 was stolen from the orbit of another sun by our own almost five billion years ago.
Researchers from Lund and Bordeaux University believe that Planet 9 was an exoplanet – a planet that orbits a star outside the solar system. Using a computer model, they have suggested Planet 9 was captured by our young sun and remained undetected until recently.
Alexander Mustill, lead author and astronomer at Lund University said: “It is almost ironic that while astronomers often find exoplanets hundreds of light years away in other solar systems, there’s probably one hiding in our own backyard.”
Stars are born in clusters, often passing each other by. It is during these periods that stars can steal planets from an orbit around another star, if for example, its original orbit was too wide around the first sun it was circling.
