This guy never got the memo: https://youtu.be/mWKDZRJWdF4
I mean, can you imagine if it changed?
Pluto is hot shit.
They say “Pluto’s not a planet,” Do you think that Pluto gives a shit?
Now and then, we all get a thought
That stops us in our tracks
Came here to make sure that was posted, LOL
people in the year 400 million when pluto explodes: this meme aged like milk
If milk still spoils in year 400m I’m out
Problem is that it doesn’t really circles but ellipses.
Every planet ellipses.
Not to the degree of Pluto, which also can’t be bothered to orbit in the solar plane
Neither can Eris, but it’s also not a planet probably
It’s more deserving of being a planet than Pluto
Stupid care bear belly lookin mf
Is this for people identifying as planets but are not read as such?
The good thing about Pluto is it’s a planet whether you believe in it or not.
What are your thoughts on Ceres?
There’s not clearing your orbit, and then there’s whatever Ceres is doing.
Typical lazy Beltalowda.
OK, how about Eris
This is all Eris’s fault, so I’m tempted to say not a planet out of spite.
Pluto is Chiron’s moon
“Pluto is not a planet”
“What is it then?”
“It’s a dwarf planet”
“A dwarf what?”
“Planet”
“So it’s a planet”
If we include Pluto, we will have 14 planets in our solar system, and I’m okay with that.
In order of proximity to the sun, we have Ceres, Pluto, Huema, MakeMake, and Eris.Granted, there’s currently only 5 officially recognized, and the IAU says there may be more than 100 objects in our solar system that qualify that are yet to be discovered.

It was reclassified, not decommissioned.
The current classification is a mess.
IMO, it should be a planet iff it can hold an atmosphere. I.e., it doesn’t actually have to have an atmosphere, but if it had any, it should have enough surface gravity to hold that one.
If you define it that way, Pluto is just barely a planet.
So whatever hypothetical density constitutes an atmosphere becomes the arbitrary line in the sand.
Well, yeah. But even so, it’s still better than the current definition. Many “planets” have not, in fact, cleared their orbit.
Planet has never been very well delineated. The Sun was a “planet”. Ceres was a “planet”.
When we find enough things to break up the classification, we make a new classification. Like “asteroid” or “dwarf planet” or “gas giant”.
I don’t think the sun is in orbit around the sun.
Similar to the arbitrarily defined density of other stuff in the same orbit. We need to draw lines somewhere to impose categories on nature.
Still a sailor guardian bitches!
The problem with recognizing Pluto is that Eris, Haumea, Makemake, Gonggong, Quaoar, Sedna, Ceres, Orcus, and perhaps also Salacia also should probably be included, and that makes for a nightmare of a mnemonic. As we all know, classification is decided on mnemonic plausibility.
Yeah, there never was an option to keep 9 planets. It was either 8, all of which are already familiar, or many many more. And they wouldn’t all be added neatly at the end either. Removing Pluto was the sensible choice.
What’s the problem with having many many planets in our solar system? You don’t have to remember them all.
We also have many many stars in our galaxy. We don’t have to know their names for them to still be stars.
You don’t ever see people calling for Ceres to be proclaimed planet, all they care about is Pluto.
I think Pluto having been widely regarded as a planet before and having a visible heart shape on it’s surface is an easier sell. I say they are both planets.
What’s the problem with having many many planets in our solar system?
You also can’t find a good problem with this, can you?
I say they are both planets.
Cool. Can you name all planets in the Solar System, in the correct order?
I can’t.
Yeah. To answer your question, I see that as the problem. If you don’t, well, we’ll have to agree to disagree on that one.
Possibly over 100.
The problem with recognizing Pluto is that Eris, Haumea, Makemake, Gonggong, Quaoar, Sedna, Ceres, Orcus, and perhaps also Salacia also should probably be included
If one uses diameter as the cutoff, then Pluto is larger than all of those.
Nah, the cutoff is “is it mostly spherical due to its own gravity?” and “has it cleared its orbit from other bodies?”
Pluto is massive enough to be spherical but did not clear its orbit from other bodies. Now its the head of its own family, the dwarf-planets.
Indeed, but Eris is only marginally smaller and a fair bit more massive, and the latter is generally more important in categorization.
Ok so we’re adding new arbitrary qualifications to hold onto the simplified image of the solar system that we learned growing up.
Pluto and the others are planets even without including them all in the mnemonic. The mnemonic is for the first 9 planets, just like you only remember the first few digits of pi.
Ceres is between Mars and Jupiter.
Pluto was not the first 9th planet. Then again we were up to 13(?) at one point.
Pluto was
Because Pluto is the 9th planet?
How are you counting?
The moons of Jupiter and Saturn were called satellite planets from their discovery until sometime in the 20th century.
The first several asteroids were called planets, until enough were discovered that the term ‘asteroid’ was invented and they were renamed.
The first Kuiper belt objects were called planets, until enough were discovered that it turns out Pluto is mostly just a particularly reflective example.
They actually know their history, which you clearly don’t

Now, you only have to remember that Makemake and Orcus are in the Kuiper belt (past Neptune’s orbit), and that maybe that Salacia is optional, and you can puzzle out the two repeated letters.
I spent too long on this.
…where’s eris?..
“Educated”
We eliminated Earth by accident.
Of course we didn’t. The International Earth-Destruction Advisory Board would have reported that…
Shit.
Not too much, what’s eris you?
It’s only a problem when you reach a certain level of astronomical knowledge. 99% of us don’t and won’t give a shit and think the people who decided Pluto’s no longer a planet are simply assholes.
All adults know what a “grandfather clause” is and are capable of applying that to Pluto.
Pluto is and will always be Hot Shit.
Pluto is and will always be Hot Shit.
Actually, it’s very cold on Pluto. Which makes Pluto cooler than Fonzie
Technically, you don’t know Fonzie’s temperature. And before you go and say “human temperature,” the Fonz is a fictional character, so all bets are off.
the people who decided Pluto’s no longer a planet
Yes. Fuck Mike Brown. I don’t know why many people still let him dictate what to think of as a planet. The concept of “planet” is entirely man-made and doesn’t follow any god given or universal criteria. While some astronomers argue that our moon is a planet too, the current criteria would even de-classify earth as a planet, should it get knocked out of our solar system.
I see Pluto as a Planet, and have yet to see a good argument against it.
Yet Mercury is in the same category as Jupiter…as though they are similar in any way. “Planet” is one of the few times science has decided to change something for the sole purpose of keeping the Earth important in its classification. I suppose we could not have 15 or 20 or 40 planets because that would be confusing…yet we have almost 1000 moons. It is ONLY because it is the Earth’s classification…no other reason. It doesn’t make anything easier or less confusing.
They could have easily made mercury, pluto, and a dozen others dwarf planets, Venus Earth and Mars terrestrial planets and the others gas planets… but that would demote Earth.
Weird left over geocentrism remaining in science like it’s the 1300s.
Er… Are you saying that scientists won’t classify Earth as a Terrestrial Planet? Because they do.. The next 4 are Jovian Planets, while others including Asteroids are called Minor Planets.
If you check the wiki article https://en.wikipedia.org/wiki/Terrestrial_planet you’ll notice some scientists consider Earth’s Moon, plus Io and Europa terrestrial planets as well.
I don’t see how it would be a demotion. Pluto is a planet, but not one of the terrestrial or Jovian Planets, but instead a minor planet, a dwarf planet. The people who insist on the 9 or 8 planets is less scientists and more about what we teach as the main planets in the solar system to like kids and such.
I’m a bit confused on your idea of scientists. They love being more specific about definitions, as do many other technical fields. Ask medicals scientists about Cancer or heart disease and they’ll explain they’re very broad terms that have many subcategories and differences, which is why there isn’t 1 easy cure. Similarly, “the common cold” is just a description of symptoms carried out by a number of different viruses from different families that our bodies just tend to react to in the same way, which is why a cure for the common cold is a ridiculous thing to hope for.
These definitions aren’t usually for scientists, but instead generalizations the public settle on because remembering everything would be too much for people who aren’t interested or involved.
I understand and completely agree wiyh your point except there are no sub categories of planets. This move was specially made (by a super minority of voters at a last minute end of the conference vote) to keep Earth’s classification as a planet more important. First of all, and frankly insane, Pluto is not under the classifocation of a planet. It is a dwarf planet that, contrary to logic, is NOT a sub category of a planet. If you look at the Euler diagram on the wiki page for dwarf planets you can see they specifically made sure planets were a stand alone category. Sub categories like you mentioned make perfect sense but would slightly diminish Earth’s “special” classification.
I would love for all of the bodies to be under a large hierarchical classification as you suggested but oddly they are not. It’s disjointed and I think done in a way specifically to spite others in a bit of a power fit.
I still classify you as a planet, Pluto. So did the old ones.
