Spooky! Solar System's Planet NINE could be discovered in the next NINE years (plus one to six), say astroboffins

Wasn't this how Newtonian mechanics was disproved?

Newtonian - i.e. Classical - mechanics hasn't been dis-proven.

It is still a perfectly valid and accurate theory for describing a lot of macroscopic situations. You don't need anything more than Classical mechanics to, for example, send a probe into orbit around Saturn via several planetary sling-shot maneuvers.

Newtonian Gravity never explained why things moved as they did, it merely gives a means (formulas) of calculating it.

GR gave us the why, and more detailed and more accurate formulas to explain and calculate the cases that Newtonian couldn't.
