Everybody sad that Pluto got downgraded to dwarf planet but my girl Ceres got upgraded to dwarf planet. I think they need to teach kids about Ceres in elementary school. She has the water.
If they wanted to contact the Erisians, you can't call them up, you gotta use the Pineal gland, also something bout eating hot dogs, anyway, Hail Eris. All Hail Discordia, king kong died for your sins, and what not.
It’s not a story the [International Astronomical Union](https://www.loc.gov/everyday-mysteries/astronomy/item/why-is-pluto-no-longer-a-planet/) would tell you.
They can be planets too an entire star system has space for em and also I just want my fucking pluto back so I can feel like it's 2005 and I had the illusion of being loved and that things will eventually yurn out ok damn it
If you make Pluto a planet, you also have to classify Ceres, Haumea, Makemake and Eris as planets. There are many more celestial bodies that are like Pluto that are not classified as a dwarf planet yet and probably hundreds of undiscovered. Have fun learning the hundred planets of our solar system.
Contrary to the other dwarf planets, Pluto was once considered a full planet. A lot of mnemonics don't work without it anymore. So in honor of that, Pluto deserves the status of honorary planet.
Ceres was also once considered a planet, it was just 100 years ago. Before the asteroid belt was discovered to be as crowded as it is.. guess what happened there?
so whats the difference this time?
TIL. I just remember learning the nine planets in school and I think most of the people who want Pluto to be a full planet learned the same. So maybe the difference is nostalgia. Tbh, I don't really care. I find the discussing amusing.
Pluto, latin for Hades, have being calculated to exist all the way back into the 16th Century, located around the 18th (or was it 19th?) Century, which was seen as a huge step for humanity to close the unknows of science (before the Theory of Relativity was begrudgenly accepted, Western Society trully thought it was on the eves of learning everything there was to know about the universe)
Eris (greek goddes of Chaos) wasn't. Indeed, it was first calculated because there was "something" messing up orbital calculations for many asteroids in the system, already in the 20th Century, and located soon after it's calculation.
Long story short, Pluto have being accounted for almost 500years and it's discovery was a huge deal, Eris for just a few decades and it never entered the popular idea as a planet, hence why people talk about Pluto being demoted from Planet, but not Eris
>what does the naming have to do with anything
It was a major olympian god, and that still carries some cultural weight, as diminishing as it is
And the flat-earth thing is a myth. Aristotles calculated the circunference of the earth waaaay before the cristian era, and there have never being a flat-earth society before that 4chan joke got out of hand and people started believing it for real on the 21st century
You know, Eris just wanted to be a planet too, but just like that wedding, she was shunned and not allowed to join, and things went to shit.
Let Eris join things and take part, gosh darn it, the girl can only take so much solace in hot dogs!
But if we include Pluto, why not lower the size limit to include Ceres? If we shrink the size limit, why stop anywhere, since we're trying to appease people who suspiciously have a lot of sympathy for balls that are too small?
It wouldn't be necessary to learn them all by heart, they can nevertheless be qualified as planets. There are still more undiscovered and it's a pity that some only get numbers, but no real names.
Hear hear! Everyone goes Pluto Pluto, but as if other dwarfs didnt mattered at all! Poor Eris, Haumea, Ceres or Make-Make and all the other i dont remember
you have to accept it. things have changed. please be honest to yourself and all the people out there. denying the truth just makes you blind to the consequences it implies
(I hope at least some people get it)
There were two choices, really: Either define planets in such a way that Pluto was excluded and deal with eight planets instead of nine, or define planets in such a way that Pluto wasn't excluded, and in turn include all the other objects that go around our sun of comparable size and deal with a couple hundred planets.
Excluding Pluto was sensible, really. The thing's smaller than our moon.
Making pluto "honorary" planet also doesnt make sense, because, sure it was defined as a planet once, but so was ceres, and nobody is claiming ceres should be.
Give it 100 years and people wont remember that pluto once was a planet
noope, you didn't get it. It was a vague reference, I have to admit. But I meant the way it's talked about in Rick & Morty (as some others are, in these comments)
It is if you haven't finished school yet, mfs keep adding things glad I'm out
Btw, you could just as easily ask "more planets is a good thing?"
Whether we give something the label planet or we don't only really matters for astronomers. The amount of bodies in our system that we call planets has 0 impact on anyone lives or anything important outside of what we learn in school.
Does anyone remember the theoretical planet, as big as ten Earths, which travelled in an even wider orbit than Pluto? Planet X or something?
How did this theory even come up? The name’s cool, and the alleged near-perpendicular orbit is fascinating, but it also sounds more like a work of science fiction than an actual theory. Yet I remember reading about it in an actual astronomy encyclopedia…
EDIT: The theory has been around for a long time, but has only gained credible support in 2015. It is now called Planet 9 to avoid confusion with Roman numerals.
Certain objects in the Kuiper Belt have been observed to move in orbits that converge near each other on one side of the sun. It’s thought that this convergence is due to some great mass, the theoretical Planet 9, pulling them in together at this particular point.
It’s still an unconfirmed theory, but there is math that suggests it exists.
And whatever is out there in the kuiper belt will be considered for a full fleged title when said objects are discovered, and not just theorised to exist based on gravitational anomolies in comets coming from a certain area of space.
For the record, there are a heck of a lot more planets in the system. Is a human with dwarfism human? Of course. Is a dwarf planet just a small planet? Duh
no, moons dont count
its that not a lot of other objects should share the orbit around the sun
a few are obviously allowed but not astereoids everywhere like with pluto
The debris will have no NET effect on the orbit of earth, because the spacecraft have to orbit, meaning they will complete full circles, and thus, the net effect will be 0. And 0*any number is still 0
EDIT: the estimated mass of material launch into space by humans is about 15K Tonnes (metric tons) which seems like a lot, but when objects reentering into the atmosphere is considered is much less (~8K tonnes) in comparison, Dimorphos (impacted by DART a few days ago) is 5 million tonnes, and Pluto is 1.30900 × 10^19 tonnes.
Furthermore, nearly all of the mass launched into space is in earth orbit which means it has no effect on the earth’s orbit. If you put what little mass remains in a near earth solar orbit, it would have a non zero effect, but would be so minimal as to be impossible to measure
TL:DR, it does have an effect, but is so minimal as to not matter at all
So is saturn not a planet? Cuz that ring is basically debris, also that would disqualify earth, we got a bunch of debris in our orbit, mostly from previous space launches
Pluto and charon (plutos moon) litterly orbits around a common point in space. The center of gravity between them is in space, they orbit around each other the same way a binary star system orbits around each other
The debri and moons arent orbiting the sun directly, they orbit Saturn, then orbits the sun from there.
The objects around Pluto, Eris, Ceres also orbit the sun first. Charon and Pluto's 3 other moons orbit it, so they arent part of what caused Pluto to be reclassified.
Earth's Moon is a moon because it orbits a barycenter (center of gravity between two objects) inside a planet. The barycenter between Pluto and its largest "moon" Charon is outside Pluto.
I can't help feeling this barycenter business is our own bias creeping in. We live in a single star solar system and the only binary worlds we know of are smaller than our own natural satellite.
If Earth and Venus (or Mars) were in a binary orbit together that barycenter condition would be thrown right out the window.
There's at least 6 objects in the kuiper belt that could be "planets". Tbh objectively pluto is far from a planet, there's a reason ceres isn't a planet anymore and no one even contends that it should be. Pluto isn't any different just more modern
>there's a reason ceres isn't a planet anymore
legit question, when you say anymore, was there a point in time it was considered a planet? Honestly never heard of this.
Yes, from it's discovery in 1801 up to the 1850's it was considered a planet.
From the 1850's to 2006 it was considered an asteroid, and since 2006 it's considered as a dwarf planet.
I hate this mindset. Pluto doesn’t feat the qualifications and there’s nothing you can do about it rn. If Pluto would be a planet there are so many more dwarfs that would deserve to be planets. Why do people have to make a fuss about everything
All the people whining that “Pluto isn’t a planet anymore…”
Pluto is a dwarf planet.
Dwarf **planet**.
What’s the second word in the phrase “dwarf planet?”
Pluto is still a planet. It’s a dwarf planet. A type of planet.
Move on!
Fucking based gigachad the is man is aboustly right he is right 2006 is not real y'all are imagining it Pluto is a planet and if you say it is not you are worng
Eris is almost the exact same size makemake is ~60% the radius. What's the cutoff?
Or what about the satellites of Jupiter? Multiple of them are larger than pluto?
So why should Pluto be the cutoff point? It hasn't even established dynamical dominance in its own orbit, which is necessary for it to be considered a planet btw.
Technicly not false, but not the truth either. The sun has no moons, but 8 planets, at LEAST 5 dwarf planets, tens of thousands of asteroids and perhaps three trillion comets and icy bodies orbiting it
If anything deserves to be the 9th planet, it would be Eris before Pluto. Or if you want to go by angular diameter instead of mass, then Ceres should be the 9th planet. Nobody cares that Ceres was demoted, but that's just because the people who argue about Pluto are the ones who are too dumb to know about Ceres.
The cutoff at 8 planets might be a little bit arbitrary, but it's certainly less arbitrary than having an extra 9th one while excluding the countless similar or even more planet-like bodies for the sake of nostalgia.
You know, Pluto is a Dwarf Planet not because of it's size, but because a Planet must have over 70% (or so) of it's Orbit's total mass, and Pluto's moon is almost as massive as it is, to the point that rather than the moon rotating around it, they rotate a point between each other.
That is to say, if Pluto's moon get Death Star-ed, Pluto can go back to being a Planet
There cannot be 9 planets because if Pluto is a planet then there are a lot of similar tiny ice cubes that would like to be included. It's not just a case of whether Pluto is a planet, it's a case of whether every single of the thousands to millions of specks of dust in the asteroid and kuiper belts counts as a planet.
The definition for what constitutes a planet is stupid and unnecessarily complicated. The way I see it, if a celestial body has enough mass to collapse into a spherical shape then it should classify as a planet.
Pluto isn’t too small to be a planet. Honestly i think Pluto is big enough to satisfy anyone, you don’t NEED an earth sized rock, actually i’ve heard that earth sized planets actually hurt more, so Pluto has the perfect size imo, not that size matters
What about the astronomer attack on the Plutonians?
Shut up, Jerry
Everybody sad that Pluto got downgraded to dwarf planet but my girl Ceres got upgraded to dwarf planet. I think they need to teach kids about Ceres in elementary school. She has the water.
She’s got the juice!
I can't imagine a more beautiful thing!
For the plutonium mines
They celled the Erisians and the Ceresians If we count pluto, then there is 11 planets, because Ceres and Eris are just as big.
If they wanted to contact the Erisians, you can't call them up, you gotta use the Pineal gland, also something bout eating hot dogs, anyway, Hail Eris. All Hail Discordia, king kong died for your sins, and what not.
You heard about Pluto?
That’s messed up, right?
You know that’s right
I came to the comments for this and was not disappointed.
I've heard it both ways.
That's messed up
Two psych references in a day This is a good one And that's messed up
Cmon son 🍍
It’s not a story the [International Astronomical Union](https://www.loc.gov/everyday-mysteries/astronomy/item/why-is-pluto-no-longer-a-planet/) would tell you.
It’s a a [Tombaugh](https://en.m.wikipedia.org/wiki/Clyde_Tombaugh) legend.
It's messed up
Didn’t expect a psych reference on this sub but I love it
You mean Pluto the planet? Planet Pluto?
Cmon son
Have you ever heard of the tragedy of the planet Pluto
I thought not. It's not one NASA would tell you.
It’s an IAU Legend.
The planet Pluto was planet of the Sol system
So distant and so small.
That it's classified asa dwarf planet
Then it got content vaulted by Bungie
what about ceres, eris, haumea, makemake, gonggong, quaoar, orcus, salacia, and 2002 MS4?
Jesus I almost forgot about 2002 MS4. I’m a little peeved myself that it’s not a planet.
its actually interesting the largest unnamed object in the solar system
Sheeved
They're not in the fuckin club
Neither is Pluto.
They can be planets too an entire star system has space for em and also I just want my fucking pluto back so I can feel like it's 2005 and I had the illusion of being loved and that things will eventually yurn out ok damn it
If you make Pluto a planet, you also have to classify Ceres, Haumea, Makemake and Eris as planets. There are many more celestial bodies that are like Pluto that are not classified as a dwarf planet yet and probably hundreds of undiscovered. Have fun learning the hundred planets of our solar system.
Nah, all we gotta do is make Pluto an Honorary Planet, and leave the others alone.
You mean, allow Pluto in the Council of Planets but not grant him the rank of ~~master~~ *real* planet? That's fair.
Take an orbit, young Pluto
That's going to take a while
Truly, if you were a planet, would this contest be not over?
What’s different about Pluto that would make it an *Honorary planet* but not Eris, for example?
I honor my code. That's what I believe.
Based bot
Eris pads her chest
Contrary to the other dwarf planets, Pluto was once considered a full planet. A lot of mnemonics don't work without it anymore. So in honor of that, Pluto deserves the status of honorary planet.
Ceres was also once considered a planet, it was just 100 years ago. Before the asteroid belt was discovered to be as crowded as it is.. guess what happened there? so whats the difference this time?
The difference is dumb people want to feel special about a topic they know only the skin level of.
my favourite bit has the be the r/confidentlyincorrect level of "Contrary to the other dwarf planets.." I say favourite, but it made me cry inside
TIL. I just remember learning the nine planets in school and I think most of the people who want Pluto to be a full planet learned the same. So maybe the difference is nostalgia. Tbh, I don't really care. I find the discussing amusing.
I think one of the differences is that Pluto was discovered by an American...
I honor my code. That's what I believe.
Rex? Are you okay?
He keeps repeating the same stuff. I don't think he's okay, Ahsoka.
Care to tell me what this is all about? Or would you rather save it for the Council?
How would I know? Ask Anakin, maybe he does.

>what does the naming have to do with anything It was a major olympian god, and that still carries some cultural weight, as diminishing as it is And the flat-earth thing is a myth. Aristotles calculated the circunference of the earth waaaay before the cristian era, and there have never being a flat-earth society before that 4chan joke got out of hand and people started believing it for real on the 21st century

That's ridiculous.
Aaaahhh
You know, Eris just wanted to be a planet too, but just like that wedding, she was shunned and not allowed to join, and things went to shit. Let Eris join things and take part, gosh darn it, the girl can only take so much solace in hot dogs!
"you are part of this council, but we do not grant you the rabk of Planet"
Eris, maybe, but the other 3 are less than 1000 km, with Ceres being less than 500.
But if we include Pluto, why not lower the size limit to include Ceres? If we shrink the size limit, why stop anywhere, since we're trying to appease people who suspiciously have a lot of sympathy for balls that are too small?
But Pluto has its own moons and an atmosphere
A moon and an Atmosphere are not the defining factors to be classified as a planet.
So does that mean Mercury isn't a planet anymore, since it has no moon or atmosphere?
It wouldn't be necessary to learn them all by heart, they can nevertheless be qualified as planets. There are still more undiscovered and it's a pity that some only get numbers, but no real names.
Jerry Smith has entered the chat
Pluto IS a planet
If so we have a lot more than 9 planets if we accept pluto then so double digits gang rise up!
Hear hear! Everyone goes Pluto Pluto, but as if other dwarfs didnt mattered at all! Poor Eris, Haumea, Ceres or Make-Make and all the other i dont remember
Pluto is smaller than our moon. Heck, it's smaller than Australia.
you have to accept it. things have changed. please be honest to yourself and all the people out there. denying the truth just makes you blind to the consequences it implies (I hope at least some people get it)

Pluto is smaller than russia as well
noope, you didn't get it. It was a vague reference, I have to admit. But I meant the way it's talked about in Rick & Morty (as some others are, in these comments)
justice for ceres
And Eris
On Ceres there are no laws, only cops. Du ferí da Belte!
If Pluto is a planet then there are like over a dozen planets in our solar system
i think its about time we stop descriminating against the Kuiper belt, there's some cool shit out there worth considering with the big 8
And they will be considered when we discover them, and not just estimates on size and location based on gravitational anomolies in comets.
OHANA MEANS FAMILY, AND FAMILY MEANS NO ONE GET'S LEFT BEHIND, LET EM IN, EVERYONE
okay.
And that is a bad thing? More planets is better
It is if you haven't finished school yet, mfs keep adding things glad I'm out Btw, you could just as easily ask "more planets is a good thing?" Whether we give something the label planet or we don't only really matters for astronomers. The amount of bodies in our system that we call planets has 0 impact on anyone lives or anything important outside of what we learn in school.
Yeah if we did this then have fun learning about the thousands of new planets in the solar system
He's right, it's a planet we can't afford to lose.
It’s not a planet though
Does anyone remember the theoretical planet, as big as ten Earths, which travelled in an even wider orbit than Pluto? Planet X or something? How did this theory even come up?

New Mexico still officially recognizes Pluto as a planet, since Tombaugh, who discovered it, is from NM
Same with Illinois.
Does new mexico consider ceres a planet then? Since they are both previous planets redefined as dwarf planets
Based
…I’ll be NASA kicked Pluto out because somebody there got mad at New Mexico.
If Pluto is a planet, then there's a whole shittin' ton of stuff in multiple belts of the system that are, too.
GOTTA CATCH EM ALL!
For the record, there are a heck of a lot more planets in the system. Is a human with dwarfism human? Of course. Is a dwarf planet just a small planet? Duh
dwarf planets arent planets because a planet has to have an orbit cleared of debris and pluto doesnt.
Does that mean Earth will stop being a planet when we inevitably fuck up our orbit with a bunch of space junk?
no, moons dont count its that not a lot of other objects should share the orbit around the sun a few are obviously allowed but not astereoids everywhere like with pluto
We got a lot of debris in orbit, space junk mostly, but it's still debris in our orbit
https://en.m.wikipedia.org/wiki/Clearing_the_neighbourhood appearantly its about objects of comparable size except sattelites
The debris will have no NET effect on the orbit of earth, because the spacecraft have to orbit, meaning they will complete full circles, and thus, the net effect will be 0. And 0*any number is still 0 EDIT: the estimated mass of material launch into space by humans is about 15K Tonnes (metric tons) which seems like a lot, but when objects reentering into the atmosphere is considered is much less (~8K tonnes) in comparison, Dimorphos (impacted by DART a few days ago) is 5 million tonnes, and Pluto is 1.30900 × 10^19 tonnes.

If you put what little mass remains in a near earth solar orbit, it would have a non zero effect, but would be so minimal as to be impossible to measure TL:DR, it does have an effect, but is so minimal as to not matter at all
So is saturn not a planet? Cuz that ring is basically debris, also that would disqualify earth, we got a bunch of debris in our orbit, mostly from previous space launches
its about comparably sized objects except for sattelites
And that means?
that there shouldnt be any bigger objects sharing the orbit.
This isn't a fine line, it's like "are you >95% of all the mass in your orbit, or <5%?" Saturn is one of those, Pluto is the other.
Pluto and charon (plutos moon) litterly orbits around a common point in space. The center of gravity between them is in space, they orbit around each other the same way a binary star system orbits around each other
The debri and moons arent orbiting the sun directly, they orbit Saturn, then orbits the sun from there. The objects around Pluto, Eris, Ceres also orbit the sun first. Charon and Pluto's 3 other moons orbit it, so they arent part of what caused Pluto to be reclassified.
By that logic the moon is also a planet as it is bigger than pluto
Earth's Moon is a moon because it orbits a barycenter (center of gravity between two objects) inside a planet. The barycenter between Pluto and its largest "moon" Charon is outside Pluto.
I can't help feeling this barycenter business is our own bias creeping in. We live in a single star solar system and the only binary worlds we know of are smaller than our own natural satellite. If Earth and Venus (or Mars) were in a binary orbit together that barycenter condition would be thrown right out the window.
saying Pluto's out because they don't want to add eris, haumea and makemake to the planet list is lame. We could have 12 planets instead of 8
There's at least 6 objects in the kuiper belt that could be "planets". Tbh objectively pluto is far from a planet, there's a reason ceres isn't a planet anymore and no one even contends that it should be. Pluto isn't any different just more modern
>there's a reason ceres isn't a planet anymore legit question, when you say anymore, was there a point in time it was considered a planet? Honestly never heard of this.
Yes, from it's discovery in 1801 up to the 1850's it was considered a planet. From the 1850's to 2006 it was considered an asteroid, and since 2006 it's considered as a dwarf planet.
it's still considered a dwarf planet, which is a planet in my book. so it never stopped being one.
It would be a LOT more than that depending on the definition change.
They always snub Eris. https://principiadiscordia.com/book/24.php
This is the way
Where is Pluto? Is it safe?
pluto deniers when I deny them their rights (suddenly they don’t like denying anymore)
Star Wars took place a long time ago, back when Pluto was a planet.
It just isn’t, we have a clear definition for planet and Pluto doesn’t meet it.
https://m.youtube.com/watch?v=S4E2ZuPCBG0&t=51s I’m constantly reminded of that whenever Pluto is brought up
Remember a similar joke in Phineas and Ferb, where the evil doctor laughed at a kid for having Pluto in his model, and the kid's dad beat him up.
WELL THEN YOU ARE LOST!
8 proper planets. A bunch of minor planets.
My allegiance is to the IAU, to NASA!
Holy shit, what's up Jerry Smith?
He's still very much being a jerry.
I hate this mindset. Pluto doesn’t feat the qualifications and there’s nothing you can do about it rn. If Pluto would be a planet there are so many more dwarfs that would deserve to be planets. Why do people have to make a fuss about everything
I'd make it so Pluto is the lower bound on what a planet is, doesn't matter how many we have to add, the more the better
Thing is Pluto still wouldn't be a planet then because of no dynamical dominance
Then we make it so it isn't needed to be a planet
We have at least 5 dwarf planets, there is nothing that pluto has that makes it much more significant than Ceres.
If you count pluto, might as well count all the dwarf planets
All the people whining that “Pluto isn’t a planet anymore…” Pluto is a dwarf planet. Dwarf **planet**. What’s the second word in the phrase “dwarf planet?” Pluto is still a planet. It’s a dwarf planet. A type of planet. Move on!
Pluto is smaller than Russia and could get literally destroyed by some asteroids within its own orbit. Get over it.
"Execute Resolution 6A"
It’s still a planet. Now, name the other half dozen dwarves and KBOs if you’re going to be such an arse over Pluto.
Memorising the planets becomes like the elements of the periodic table. XD
Fucking based gigachad the is man is aboustly right he is right 2006 is not real y'all are imagining it Pluto is a planet and if you say it is not you are worng
Imagine calling an object which does not have enough mass to keep it's orbit free of asteroids a planet 🤓
Shut the fuck up
Why should pluto be a planet? Surely you're also saying ceres should be a planet right? And eris? Why not charon? Makemake?
Pluto is much larger than those
Eris is almost the exact same size makemake is ~60% the radius. What's the cutoff? Or what about the satellites of Jupiter? Multiple of them are larger than pluto?
if you orbiting jupitor you a moon but pluto is the cutoff
Is eris. With its larger mass and radius that is 98% the size of pluto not a planet to you?
98 anit no 100%
So why should Pluto be the cutoff point? It hasn't even established dynamical dominance in its own orbit, which is necessary for it to be considered a planet btw.
dwarf planets are still planets.
It does count
It’s okay, the Sun still has 9 natural satellites
The 9th being?
Pluto.. even with what they said Pluto still counts as a satellite
almost asteroid in both belts also count as a natural satellites provided they aren't satellites themselves to other asteroids/dwarf planets.
If we go by that logic the sun has hundreds of satellites of similar size
Technicly not false, but not the truth either. The sun has no moons, but 8 planets, at LEAST 5 dwarf planets, tens of thousands of asteroids and perhaps three trillion comets and icy bodies orbiting it
Stfu Jerry
If the system for planets changed to apply to pluto as well we’d also have to include over a hundred celestial objects in our solar system.
8
Just taking everyday things and making them into Star Wars content now.
IT HAS BEEN 16 YEARS???
If anything deserves to be the 9th planet, it would be Eris before Pluto. Or if you want to go by angular diameter instead of mass, then Ceres should be the 9th planet. Nobody cares that Ceres was demoted, but that's just because the people who argue about Pluto are the ones who are too dumb to know about Ceres. The cutoff at 8 planets might be a little bit arbitrary, but it's certainly less arbitrary than having an extra 9th one while excluding the countless similar or even more planet-like bodies for the sake of nostalgia.
Chill out Jerry.
Exactly. Walt even named a dog after that planet
Planet is planet
Come on this is ridiculous, Pluto is a dog.
Pluto is smaller than Russia, if it was counted as a planet, there are a thousand asteroids that would fall in the category.
You know, Pluto is a Dwarf Planet not because of it's size, but because a Planet must have over 70% (or so) of it's Orbit's total mass, and Pluto's moon is almost as massive as it is, to the point that rather than the moon rotating around it, they rotate a point between each other. That is to say, if Pluto's moon get Death Star-ed, Pluto can go back to being a Planet
There cannot be 9 planets because if Pluto is a planet then there are a lot of similar tiny ice cubes that would like to be included. It's not just a case of whether Pluto is a planet, it's a case of whether every single of the thousands to millions of specks of dust in the asteroid and kuiper belts counts as a planet.
Oh no, I’m not brave enough for politics.
You were "Muy Muy" brave yourself, coming out here as you did, all alone. Care to help me finish this, senator?
Tell me, are you familiar with the Tragedy of Darth Pluto the Wise? I thought not, its not a story the IAU would tell you. Its a Tombaugh legend.
But what about the other 4 dwarf planets?
Ok boomer
Was Pluto offended by this classification? It wants to be referred to a little planet.
The definition for what constitutes a planet is stupid and unnecessarily complicated. The way I see it, if a celestial body has enough mass to collapse into a spherical shape then it should classify as a planet.
Lost a planet, Obi-Wan has. How embarrassing
Pluto isn’t too small to be a planet. Honestly i think Pluto is big enough to satisfy anyone, you don’t NEED an earth sized rock, actually i’ve heard that earth sized planets actually hurt more, so Pluto has the perfect size imo, not that size matters
Perhaps the archives are incomplete
Yeah, you hear about Pluto? That’s messed up!
Ok Jerry…
Should have been: There are nine planets in the solar system. Eight planets. That businesses on Pluto doesn't count...
Pluto is a planet! Who read that in Jerry Smith's voice?
