Newton's Laws of Gravity Are Working

A new planet, uranus, is farther away than the then farthestmost planet, saturn. They've found out that it's not following newton's laws of gravity. So they said, maybe there's an object out there remains to be discovered whose gravity is influencing the trajectory of uranus. And so they looked. Sure enough, discovered a new planet that became neptune. The planet neptune, o ks, good to us.
