Researchers predict: " The gravity of the 9th planet may be the cause of the Kuiper belt object group being pulled into orbit perpendicular to the orbit of the 9th planet (blue elliptical path). 5 previously discovered objects will soon adapt to this . "

If a planet is 10 times more massive than the Earth, orbits the Sun and is farther away than Neptune, it will affect the trajectory of objects near it. "The five objects identified will soon match the predicted orbit (as shown in the figure below), " the researchers said.
