i was briefly on the train of "pluto is a planet and so is EVERY DWARF PLANET" when i was little, but thinking back, it was definitely just an excuse for me to name all the dwarf planets i knew so ppl would be impressed with me for knowing all the secret ones like ceres and haumea and quaoar.

out of curiosity... did you make this post as an excuse for you to name all the dwarf planets you knew so people would be impressed with you? because if so it worked.

no, if that was my aim then i would have also named Eris, Sedna, Varuna, Makemake and Gonggong.

sedna is my favourite solar system body hands down. why is its orbit like that.

i love it so much it's beautiful, i'm glad to see it recognized

the leading theory is some bully planet way out there is skewing up all the orbits. sedna's orbital period is 11,000 years btw

Turn your heart to the stars

Fun fact: Those of us taught the "nine planets" thing between 1979-1999 were lied to (in a way). Not just because of Pluto's weird status, but because it was the eighth planet from the sun during those two decades. Its orbit is so off kilter to the rest of the planets that it switches positions (relative to the sun, not orbits) with Neptune.

And remember kids, Pluto isn't a planet unless Ceres, Makemake, Haumea and Eris are, too! Ceres was discovered a 129 years before Pluto (1801 vs 1930), Eris is slightly bigger (and was going to become the 10th planet, which sparked the need for further classification in what constitutes a planet), Makemake and Haumea are bigger than Ceres.

Ceres and Makemake don't have moons, so maybe you can ignore them for being little and moonless (rude--Ceres was originally classified as a planet, just like Pluto!), but Eris definitely deserves its name remembered.

We may actually have up to fifty dwarf planets (which are still planets, just little) in our solar system, and either a massive exoplanet that we can't see yet or a teeny black hole (5cm) out past Neptune, based on the same kind of data that originally found Pluto! (It wasn't actually seen for quite a while after its existence was hypothesized by its effects on the orbits of Neptune and Uranus).

Anyway, hope you enjoyed learning with me!
