It's hard to justify counting Pluto without counting Eris:

- Eris is more massive than Pluto (1.6e22kg versus Pluto's 1.3e22kg)

- Eris is only slightly smaller than Pluto, at 2326km diameter (more than your arbitrary 2000km cutoff)

- The orbit of Eris crosses Pluto's, so it may be closer to the Sun part of the time https://solarstory.net/img/articles/big/orbit-of-eris.jpg

Agreed. Eris is the one I was referring to in my comment. Instead of removing Pluto, just add one planet(Eris).

On reread that probably wasn't clear, since I still think of Pluto as a planet.
