just wait for the 9th planet
If the hypothetical planet that messes up Kuiper object orbits gets actually discovered, it will almost certainly be
1. a gas/ice giant, and
2. a dwarf planet under the current definition (because of not "having cleared its orbit")
Then the whole system will probably collapse under the silliness of having a dwarf giant planet.
By the way, the Moon is not a moon, it's one half of a binary planet. Not sure which idiot called it Moon but it should obviously be renamed. I propose to call it the planet Minerva going forward.
