“Planet” is about an astronomic object’s relation to other objects. That’s why it’s called a planet - a wanderer. If you want a convenient term for spherical astronomic bodies that aren’t stars, white dwarfs, black dwarfs, brown dwarfs, neutron stars, black holes, or tennis balls shot from a spaceship’s airlock, invent your own. It’s a free language.

That said, I don’t think you understand what a majority is, since it answers or contradicts half your remarks. A double planet might have one planet and a moon or two dwarf planets. A planet may have a dwarf planet in its L3 point. A planet ejected from a star system becomes a rogue planet.

Dwarf planets, rogue planets, double planets, and planetoids all aren’t planets.
