What do you define as a planet though? If you consider our sun a frame of reference, you might find that technically some far away objects bigger than the sun have complex periodical movements around the sun.

Well the definition that removed pluto from being a planet is this:

I think that's an interesting question, but the search being described is for a fairly specific kind of object with constrained parameters: https://en.wikipedia.org/wiki/Planet_Nine

I'm pretty sure the definition would include having the sun as the major gravitational force acting on the object.

Are you suggesting that the galaxy revolves around the sun? Heresy!

definition of a planet as follows: a planet is what ever arbitrary metrics Brown can come up with that demotes Pluto and includes the other 8 (sort of) so that he can write papers / gain fame / etc. They didn't come up with criteria and found Pluto didn't fit, they kept coming up with criteria UNTIL Pluto didn't fit and the other planets did fit.

Brown has no army over me, and I don't buy into the academic nonsense. Pluto is a planet.
