- Izkata 3y ago> Batygin and Brown nicknamed their predicted object "Planet Nine," but the actual naming rights of an object go to the person who actually discovers it. The name used during previous hunts for the long suspected giant, undiscovered object beyond Neptune is "Planet X." It's the same thing. These researchers just chose a different name. And the article does use "planet X" more than "planet 9"/"planet nine".
