I read that part of the planet 9 claim is that the planets orbit 6 degrees off from the rotation of the sun. Since we're we're made from the same disk, it should be the same. Isn't a simpler explaination for at least that claim that the sun itself simply turned? Don't all spinning object go through precession or are stars super stable? The sun probably was hit by proto-planets of various sizes in its early days, shouldn't that start it wobbling?
