Deci este planeta ce nu orbiteaza nici o stea si nu provine dintr-o pitica bruna e prea mica s-au ce spune aici.

And yet PSO J318.5-22 is all by itself, without a host star.


the team concluded that PSO J318.5-22 belongs to a collection of young stars called the Beta Pictoris Moving Group that formed about 12 million years ago. In fact, the eponymous star of the group, Beta Pictoris, has a young gas-giant planet in orbit around it. PSO J318.5-22 is even lower in mass than the Beta Pictoris planet and probably formed in a different fashion
