“Planet Nine” is a hypothetical planet, way far out beyond the orbit of the last planet Neptune, that many think may influence the orbits of small objects beyond, perhaps causing them to fall in towards the Sun—and the rest of the solar system—every now and then. YouTube creator Mark Rober gives a pretty concise video, demonstrating just how far would a potential Planet Nine be, in a scale model of the solar system where the Sun is the size of a soccer ball.
