Caltech scientists have found evidence of a ninth planet at the edge of the solar system. They noticed some space rocks in the Kuiper Belt—a region of the solar system beyond Neptune—were travelling along highly unusual orbits. This, they said, could be explained by the presence of a massive planet, the gravity from which was pulling the objects into these orbits.
