Scoperto un nuovo potenziale pianeta nano ai confini del Sistema solare: l’oggetto, che si trova oltre l’orbita di Nettuno, è stato provvisoriamente denominato 2017 OF201, ha un diametro stimato di 700 chilometri e gira attorno al Sole lungo un’orbita estrema che completa in 25.000 anni.
Il suo ritrovamento è stato ufficializzato dal Minor Planet Center dell’Unione Astronomica Internazionale e potrebbe sconfessare la presenza di un ipotetico e gigantesco nono pianeta ancora da scoprire, il cosiddetto Pianeta X.
Il nuovo corpo celeste, potenziale “cugino” di Plutone, è stato individuato da un gruppo di astronomi di Princeton in 19 immagini astronomiche catturate nell’arco di sette anni dal Victor M. Blanco Telescope e dal Canada France Hawaii Telescope.
