It’s not really big. There are multiple Pluto like planetoids. Also there is a hunk of rock in the asteroid belt youcould name a planet.

How can we even know it’s a planet when we haven’t observed a single orbit, yet?
Maybe it’s just a really big comet.

By measuring how fast it’s moving and where it is you can find the orbit

We’ve observed enough of its orbit to know what shape it is.

And who could blame it?
