Evidence Continues To Mount For Ninth Planet

"We simulated the solar system’s motion. Planet 9 forces the solar system to slowly wobble. If Planet 9 is out there, we are in the process of wobbling right now, as we speak! But it happens very slowly, a few degrees tilt per billion years. Meanwhile the sun is not wobbling much,  so it looks like the sun is tilted. A range of Planet 9 parameters cause exactly the configuration of the sun that we see today.
