# If “9 th planet” is ejected by Jupiter or Saturn, why does it have a very far perihelion?

If the "9 th planet" is ejected by Jupiter or Saturn, I think the perihelion should be near Jupiter and Saturn, but now the predicted orbit is very far away from Netpune, why would that happen?

• Sorry for my ignorant comment, but I'd guess it must've had two major disturbances, perhaps one interstellar. The formation and ejection of a fifth gas giant, larger than Nine (plutwo:-)) fits some simulations. Maybe that event brought something intersting about. – LocalFluff Apr 12 '16 at 13:42
