A bit jealous that the dinosaur guys got Nanotyrannus back but we’re still here in the big 2026 saying that Pluto isn’t a planet.

It’s outrageous it’s unfair.

@konstructivizm I'm sure this is friggin' AI generated rubbish. I've looked at the actual images of the nebula and none of them look something like this.

@_MoonArt__ By the way, the boy's name is Sanny.

@_MoonArt__ Thanks for the opportunity! Try this young boy.

@Skullz_Skeleton TikTok. I never use it, and as for Discord, I used to but I'm not used to it anymore.

Earth's axis isn't fixed - it slowly wobbles (precession) against the distant stars. Every ~26,000 years, Polaris, Alderamin, Vega, and Thuban take turns as the North Star.

@AsteroidEnergy @GregWAutry Since we don't really have very sophisticated advancements to our technology, for now we won't know whether some exoplanets have cleared their orbits or not, especially terrestrials or smaller. If there is no debris around Pluto-sized exoplanets when we find any, what then?

[Jack Mitch Culberson @JackMtCulberson]

@AsteroidEnergy @GregWAutry Orbit-clearing would have to depend on the distance of the object around the star. If there are exoplanets about the size of Pluto around a red dwarf star, how can you apply orbit clearing when you don't see any form of debris around it?

[Jack Mitch Culberson @JackMtCulberson]

@AsteroidEnergy @GregWAutry Interesting, but that leaves behind rogue planets.

The most problematic here is orbit-clearing or gravitational dominance, which would have to depend on the star it orbits. If so, what would happen if dwarf planets beyond our Solar System are discovered?

@Dominos_UK Anchovies always belong on pizza. I will not change my stance; their saltiness goes well with the tomato sauce. (but if you don't like anchovies; your taste, your preference)

Love my Marinara pizza all the way.

The geophysical definition is the only definition that makes sense.

@Kraftitain All dwarf planets are true planets

@Twooneart21 Thanks for the opportunity!

Here's my latest:

[Laurel Kornfeld @plutosavior]

@JackMtCulberson @ThePrimalDino @AlanStern Many people, including many planetary scientists, never stopped considering Pluto a planet. The IAU definition is just one view in an ongoing debate. @AlanStern @DrPhiltill @nasaman58

[Jack Mitch Culberson @JackMtCulberson]

@Mary_ork I have several but I have some that are still work-in-progress and I'm trying to fix as much of the plot as I possibly can.

[Jack Mitch Culberson @JackMtCulberson]

@plutosavior @AlanStern @DrPhiltill @rookisaacman Sir Isaacman, you might want review this journal article that I wrote about this issue on the IAU's planet definition. I would like to hear your opinion about this. Thank you!

"Nearly 20 Years Later, Planet Definition Issue Still Lingers"

I genuinely believe something has to overthrow the IAU definition since there is no definitive answer to its third criterion.

[Jack Mitch Culberson @JackMtCulberson]

@ThePrimalDino This needs to change. If it's all about keeping the number of planets small, then that cannot be a good enough excuse just to exclude Pluto. But it shouldn't be only about Pluto; it should be all non-stellar objects rounded enough by their own gravity. @plutosavior @AlanStern

[Greg Autry🚀 @GregWAutry]

Pluto is a planet, as are all non-star objects that have sufficient mass to be gravitationally pulled into a sphere. WHAT things - their characteristics - are is the basis for scientific classification and why planetary scientists generally agree that Pluto is a planet. Where things are observed obsesses astronomers but is not a basis for classification of those things. (A penguin is a penguin regardless of if is in the Southern Hemisphere or Sea World.)
