Dwarf Planets: The Lesser Worlds

The Solar System is home to eight main planets, but this is far from the full picture. Hidden beyond the orbit of Neptune are dozens of small, icy worlds, known as Dwarf Planets, or Minor Planets! The best example is Pluto, but there are dozens more orbiting within the same band of material at the outer Solar System. Today, we will visit these frozen, far out worlds first hand.

Pluto lost its status cause it didnt clean its backyard

[@LeoStaley]

The problem is, the hypothetical planet 9, despite being up to 10x the mass of the earth, would be classified as a dwarf planet, because all these other dwarf planets that are still technically it its neighborhood. Shit, neptune should be a dwarf planet because it hasn't cleared pluto out of its neighborhood.

[@fotnite_]

@@LeoStaley Not necessarily. Planet 9's theoretical orbit is tilted pretty far off axis, the major evidence of which is the lack of trans-neptunian object orbiting in that region, and the disturbance of objects that approach. Thats why we're calling it Planet 9, and not a theoretical gaseous dwarf planet. Additionally, the area around a planet doesn't have to be completely clear. If it did, then only Mercury would count as a planet, since all of the other planets drag significant debris around with them at their Lagrange points, or even as satellites.

[@LeoStaley]

@@fotnite_ those are all just several more reasons why "cleared its neighborhood" is a terrible criterion. A clearer, more substantive, and more useful criterion, which would have distinguished pluto and other TNOs from the planets, would have been based on whether the object orbits on the regular orbital plane of the star or not. The vote for changing the planet definition was actually controversial, and did not provide any kind of adequate debate, or even reach anything like a consensus among astronomers.
