Remember Planet X, that small planet just past Pluto used as a topic in old science fiction movies and cartoons? Well now that fictional planet is a reality! No, not that weird military base or whatever, this is the real thing! This Texas-sized planet is black as coal, and has an orbit more then double the length of Pluto's. Scientists believe that it was formed in the Oort Cloud, then was pulled into orbit around the Sun. Could there be other planets like this one in our galaxy? In our solar system? We can only guess.
