But another theory suggests that something bigger lies beyond the belt: some believe that a rogue planet that was ejected from the inner solar system dragged the sednoids with it.VP113 shares some parameters with Sedna, which suggests the gravitational influence of a larger planet. A computer simulation showed that there could be an unseen planet five times the size of Earth lying 23 billion miles away from the sun, influencing VP113 and maybe even other sednoids that have yet to be discovered. That, however, is just a theory, and researchers say that while they believe something is happening in the far corners of space, they'll need to find many more planetoids like VP113 to definitively prove anything.
