Isn't Pluto technically still a planet, but a dwarf planet because of its orbit or because it didn't clear other deep space objects or say pretty please can I be a planet again or something?

so, Pluto takes the role of the Afghanistan Clusterfark for the American Libby media?

If they allowed Pluto, they would've needed to add a lot more space rocks that are bigger than it.

They haven't found the Mass Effect drive yet.

For some reason, placing the definition of TNO in a photo caption at the end of the article seemed like a good idea.

In the near future, astronomers will benefit from the presence of next-generation telescopes like the James Webb Space Telescope (JWST) and the Nancy Grace Roman Space Telescope (RST).

I've already seen enough of Nancy Grace tyvm.

8 planets + 5 dwarf planets = 13. A dwarf planet can't be a proper planet because of triskaidekaphobia.

It is useful to categorize things. And adding potentially well over a hundred TNOs to the list of planets reduces the usefulness of that category. So you set up a new category, the same as was done for asteroids in the 1850s.

You then either end up with what we have now, eight planets and a bunch of dwarf planets or you come up with a new name for the eight planets and call everything planets.

For various cultural and practical reasons it makes more sense to have the right planets.

Not to mention Pluto would never have even been considered a planet in the first place if not for its size/mass being way overestimated from the start.

Dwarf planets are not planets. English is annoying but that's how it goes sometime

Every proper planet has "cleared its orbit" a few orders of magnitude more than Pluto according to every quantitative definition people use

It is the same reason why the asteroids are no longer called planets. When it became clear there numbers are legion, astronomers said "fark this" and said that they are no longer planets.

Well there are a lot of these things in the outer Solar System. From Mike Brown's web site:

As of Tue Feb 23 2021
there are:
10 objects which are nearly certainly dwarf planets,
27 objects which are highly likely to be dwarf planets,
68 objects which are likely to be dwarf planets,
130 objects which are probably dwarf planets, and
741 objects which are possibly dwarf planets.

There are undoubtedly many yet to be sighted. The once pst Neptune have more in common with each other than they do with the eight known planets.

TNOs?  I don't believe they exist.

Pluto is a planet.  A DWARF planet.

Just like four of our planets are Gas Giants.

Potato, pototo.

That used to be the terms used, but these days, Uranus and Neptune are considered to be ice giants.

/It's almost like terminology evolves as we understand more about things.

Yes.  It just make the universe MORE INTERESTING!

No, Dwarf Planets are not a subset of planets they are a separate class of objects.

There are eight planets in our solar system, divided between the four inner, terrestrial planets and the four outer giant planets.

Orcus and Vanth are in exactly the same orbit as Pluto and Charon just 120 degrees out of phase. Pretty much the same size too. So if Pluto is a planet then Orcus must be a planet.
On the other hand both can be thought of bits of debris orbiting in resonance to the planet Neptune in much the same way the Trojan Asteroids orbit in resonance with Jupiter. I personally think this is more elegant summation.
