in France and his team discovered a potential rogue alien planet CFBDSIR2149 using the Canada-France-Hawaii Telescope, wandering alone just 100 light-years from Earth, suggesting that such starless worlds may be extremely common across the galaxy.The free-floating object, called CFBDSIR2149, is likely a gas giant planet four to seven times more massive than Jupiter, scientists say in a new study unveiled today (Nov. 14). The planet cruises unbound through space relatively close to Earth (in astronomical terms; the Milky Way galaxy is 100,000 light-years wide), perhaps after being booted from its own solar system. The new found object appears to be among a stream of young stars called the AB Doradus moving group, the closest such stream to our own solar system. Scientists think the AB Doradus stars all formed together between 50 million and 120 million years ago. If CFBDSIR2149 is indeed associated with the group — and researchers cite a nearly 90 percent probability — then the object is similarly young.
