Astronomers claim Pluto should be a planet based on new research - Sensationalist Headlines

Personally I'd go with "large enough that gravity has made the object spherical and in a roughly spherical orbit around the sun" as the cutoff point for a planet, which would include several other dwarf planets like Ceres but not bodies like Eris which has a very elliptical orbit (aphelion of 98AU and perihelion of 38AU).

Pluto is a glazed timbit https://images.chickadvisor.com/item/48327/original/cbc03633b681307bb16ae87d393b2808.jpg

Doesn't the 'clearing its neighbourhood' requirement remove most of the asteroids, as well?

Adopting this definition would see roughly 110 objects in the solar system classified as "full-fledged" planets, including dwarf planets and moon planets such as Ceres, Pluto, Charon, and our own moon. Hmm, not so sure on this one.

it's not a planet

I don't know why people can't just be fine with it as a dwarf planet, it's still a planet but just of the dwarf variant.

pluto's a bitch

Pluto's just so different from the other planets, it makes things simpler to put it in a different category. It crosses the orbit of another planet, it's not orbiting on the same plane, and it's way smaller than any other planet (even smaller than our moon).

I don't know why people complained about it being classified as a Dwarf planet when it technically means it has the honor of being the first discovered Dwarf planet ever.

it's a tiny people planet and that's final

pluto you're doing great sweetie x

Leave it as a dwarf planet and be done with it

Are those like Munchkins?

There's nothing "intuitive" about 100 random moons and dwarf planets being considered actual planets. There's a meaningful distinction to be made here and calling every round thing that isn't a star a planet just confuses.

It's a sloppy definition they claim that labelling all 100+ spherical bodies 'planets' will make education and discussion more intuitive but how are school kids going to be taught about all 100+ bodies? schools will focus on the 'main' 8(9) and brush over the intricacies of the dwarf planets and smaller bodies, so the OG 8 will inevitably have a shitty new name like 'major planet' popularised, and we will have the same split with worse names, and whether or not pluto is included in your kid's model solar system will continue to be a raging debate I really respect the methodology in trying to align these official definitions with the way actual scholarly work refer to stuff, but I can't help but feel if your solution ends up counting the moon as a planet, you're kind of failing in that department? which is probably exactly the kind of shake-up and confusion which the IAU worked extremely hard to avoid in their recategorisation

Pluto is my spirit planet.

On all levels but physical, I am Pluto.

"Astronomers claim Pluto has somehow gotten a gun in its orbit, and is aiming it directly at us.'"

Someone didn't read the article... awkward...

Because anything Dwarf is weird and shouldn't be included with the rest of the class.

I don't think that's what any of these scientists care about. They just want it to be defined accurately

Wait a second, zoom in on that edge and enhance. https://files.facepunch.com/forum/upload/110884/c0a14dea-ecce-4181-b800-6a1c9648a14c/pluto.PNG

Mercury is smaller two moons: Ganymede and Titan. Pluto, on the other hand, is not only smaller than seven moons: (Ganymede, Callisto, Io, Europa, our Moon, Titan and Triton), but is lighter than another dwarf planet: Eris, the very dwarf plant that required Pluto's redefinition. http://www.coolspacefacts.com/wp-content/uploads/2015/11/planets-and-satellite-moons.jpg Pluto is tiny. It's diameter is half of that of the United States of America and it'd take more than 450 of them combined to come up short of the mass of the Earth. Eris is not shown here, but is nearly exactly as large as Pluto: both are 23XX km in diameter, but Eris is nearly a third heavier than Pluto's mass. By this regard, if Pluto is a planet, Eris is also a planet, as is any other discovered object of similar size, which we probably will find in addition to potentially a lost gas giant predicted by creation models and object trajectories. The current definition of a dwarf moon is excellent, concise and logical, and Pluto should remain a dwarf planet because it has not cleared the region of similarly-sized bodies.

You're not a planet

We grew up with nine planets, goddammit.

It's full of stars!

Well you either get eight or at least ten, you can't exactly have a nice solution here.

you heard about what they did to pluto? thats messed up right
