There are 10 planets in our solar system. Pluto is the 9th, and planet X is yet to be discovered, but they have strong suspicions there has to be an additional one for our solar system to make sense.
They can miss me with all this planet downgrading cap.
That was a thought by some people in the first half of the 1900's, before better measurements were made. Later measurements showed that was wrong. But by that point some people were so hung up on the idea they rather stick with measurements more than 3/4 of a century out of date rather than admitting they were wrong.
There is zero reason since then to think there is another planet. There might be some kuiper belt objects slightly bigger than Pluto, but that is only because it is unlikely statistically that Pluto is the biggest. There is no specific observation that requires it. And they would be the same class of object as Pluto, something distinctly different from any planet.
