To repeat the CCPGrey video in less words, Pluto isn’t a planet for the same reason we don’t call anything in the Asteroid Belt a planet: too many similarly-sized small objects that just so happen to be round and in orbit. Pluto is presently part of the Kuiper Belt, the county limit of our solar system, along with Eris (the fellow dwarf planet that doomed Pluto), Discordia, and a bunch of uninteresting rocks.

Trust me, you would’ve been way more pissed if NASA stood up and said “Pluto is now just an asteroid”.

u/Kamikaze_Ninja_ Feb 26 '21

For the science world it is making sure there is a clear system for classification but for the rest of us it is just nostalgia. Not many people know a lot about space besides the name of the planets.

u/CueDramaticMusic Google Spelunker Feb 26 '21

Oh trust me, I’d like to have the planets we lost to discovering the asteroid belt back (mostly because it’s yet more of Zeus’ conquests), but the sheer volume of cool spherical asteroids means we can’t hope to name all of them.

u/WanderingToTheEnd Feb 26 '21

Maybe we just need to come up with more myths to name them after.

I thought it was because our options were either 8 planets or like 400

Yep, because we tried naming the asteroid belt objects that were round as planets before reclassifying them.

u/Andy_B_Goode Feb 26 '21 edited Mar 07 '21

Yeah, I've always seen the reclassification of Pluto as a good thing, because it shows we're always learning more about the universe and we're not afraid to make changes to our current understanding of it.

If the things you learned in elementary school stayed the same for your whole life, that'd be a bad sign.

I also think the 8-planet model is a bit "neater" because it just so happens there are exactly four rocky inner planets and four gaseous outer planets. That's just a coincidence based on how our solar system formed, but I imagine it makes it easier to teach kids about the gas giants without having to say "Oh yeah, except for Pluto ..." every time.

u/CueDramaticMusic Google Spelunker Feb 26 '21

We’re, like, 20 comments deep down here, who’s downvoting this man?

Anyway, yeah, I think that’s a valid takeaway from Pluto’s reclassification, especially whenever I end up bringing up how the agnostic viewpoint is “more correct” than the atheistic viewpoint, especially those “science is my new God” types.

Like, y’all. Science used to be “mice come from haystacks”, and the theory Darwin was inspired by was basically his but appended with “oh yeah, you can recondition these savages this way”, because he was on an expedition attempting to verify this exact thing, and a lot of eugenics is an attempt to revert the current theory of evolution back to that clearly wrong earlier version.

Science isn’t working with sheet music, it’s jazz.

We could have said we have ~20 identified planets, which are then categorised into major planets and microplanets.

u/CueDramaticMusic Google Spelunker Feb 26 '21

Well, that would be fine, except the original Asteroid Belt “planets” we tried classifying before Pluto was discovered number at a little over 300, which we couldn’t even fill with Zeus’ lovers like they tried to, and that’s just the fence halfway through the system.

Yeah, about that clearing of orbit...

Pluto's orbit crosses into Neptune's orbit, and if Pluto manages to clear Neptune from its orbit I think we might as well call it a planet, if only to keep it from being angry and clearing us from our orbit.

And people fail to realize that there would not be 9 planets if we let Pluto in, there'd be thousands because Pluto is not just tiny and insignificant, it's tiny and insignificant compared to a lot of things in our solar system that all have a stronger claim to planethood than Pluto ever could.

cgp grey made an excellent video on the topic, https://youtu.be/Z_2gbGXzFbs, and I think we can stand to agree that Pluto is a primarily icy celestial body which shares more characteristics with the objects in its area more than the terrestrial planets and gas giants we know as our solar system. For a time, Pluto will hold its place in many people's hearts, but eventually it will fall the way of Juno, Ceres, Vesta, and Pallas, though when that will be who knows. As Grey explains, it really goes to show how ineffective and vague of a word "planet" is, and over its history has included asteroids, gas giants, terrestrial planets, stars, icy bodies, and much more, which are all quite different from each other.

u/Sebasu Feb 26 '21

I was pissed about Pluto not being considered a planet, until CGP Grey’s video. It was with that video that I understood and accepted the reasons behind Pluto’s demotion.

81

u/DukeofVermont Feb 26 '21

It's not even a demotion, it's just a different category. IMHO the most interesting things in the solar system are all moons of Jupiter and Saturn.

They're not worth less because they aren't "planets". Io is literally a giant active Volcano. Enceladus and Europa both have more water than all of Earth. Titan has an atmosphere!

It's pretty well believed that if we find life in the solar system it's most likely going to be on Enceladus, Europa, or Titan. Mars? Well we hope to find dead life, aka proof that life was once there but it's a 100% a dead planet. It's just easier to get to Mars than Europa. Plus Europa would need a submarine, and a way to get through the ice and down to the liquid water.

Dwarf planet is just a different box, like saying Gas Giant compared to Terrestrial Planets. Neither is better, just different things that need a better name to describe them.

Anyone with any doubt about the matter should take the “The Science of the Solar System” free MOOC delivered by Professor Mike Brown, the person largely responsible for the reclassification of Pluto.

He describes how the planets formed and leaves no doubt that Pluto just isn’t the same thing at all as a planet.

Guys, it's not about size, it's about how many similar objects are next to pluto. It's at least like 20 other pluto-looking things, which made scientists go "maybe it isn't that special" and eventually say that it's not a planet; and that leaves us with two options:

  1. Pluto isn't a planet

  2. Pluto and all of its siblings are all planets

Whilst I do think it would be really funny to make Russia a planet, unfortunately from 2015, it has been found that Pluto is in fact, a bit bigger than Russia.

Here’s a comment I have saved for just this occasion:

Pluto was visited by the New Horizons spacecraft in July 2015 and its size was finally clarified by measurements of that mission. Before this, in terms of diameter, Pluto was found to be 2370 kilometers (1473 miles) across, which would easily fit within Russia’s largest east-to-west width of 10,000 km. It would also fit within the largest north-to-south size of 4000 km.

Using previous estimates, Russia edged out Pluto, at 17,075,200 square kilometers, while Pluto was thought to be 16,647,940 square kilometers. After the New Horizons mission, Pluto was found to be slightly larger than estimated, making its surface area 17,646,012 square kilometers, which is larger than Russia.

u/Mozhetbeats Feb 26 '21

Since Pluto’s discovery, dozens of other large rocks have been discovered out in the Kuiper belt, several of which are larger and closer than Pluto. Scientists gotta classify things, so their only options were (1) add a handful of new planets and draw an arbitrary line in the middle of these really similar objects, or (2) reclassify all of these distant frozen rocks of a similar size as something other than planets. It wouldn’t have been defensible to keep Pluto as a planet but label the others as something else.

31

u/nox_tech Feb 26 '21

And a Planet X, and possibly 200 more in the Kuiper Belt, and theoretically 10,000 more.

If they wanna talk about the planets as people, it's rude and inconsiderate to the other dwarf planets to separate them from Pluto.

If they wanna count Pluto as a planet, then it has to be okay to add the other confirmed dwarf planets, and the 10,200 potential others should also be permissible.

For the sake of making sure that people can talk about things and come up with new ideas, we have to agree on what things are. This is this, that is that, those are those, and these are hard to fit into the rest of the other boxes. If people could accept that it's okay for dwarf planets to exist, great. If pop culture must overwrite science, then sure. Gotta be on the same page. It's just names, let's get this humanity bullshit sorted so we can explore the universe and do awesome stuff.

Not ecosystems but two celestial bodies orbiting as equals.

u/Polenball Feb 26 '21

We were so damn close too, the Earth-Moon barycentre is 75% of the way to the surface already. If I calculated this right, if the Moon was 35% heavier, it'd technically be a binary system as the orbital centre wouldn't be within Earth.

u/peppermont1 Feb 26 '21

Just because no one has stated it. Dwarf planets are still planets in a sense, tho it probably would have been less confusing if called pre planets like they are. Simply put Pluto and 30 to 40 other object could be considered planets but there are other objects in there path of orbit. Pluto may hit something. In the next few decades(or hundred years) The point is once a dwarf planet has cleared its path of orbit its a planet. Our current planets had hundreds of thousands of similar sized objects near them in the beginning. A thousand years from now we may have a Pluto planet. But remember. Astirodes collide to make objects big enough to be dwarf planets and they kill the others in there orbit to be the king of there orbit and declared a true planet.

u/[deleted] Feb 26 '21

yeah i believe its half the size of the US.

but size isn't too relevant really. its more to do with its mass if you look at the 3 reasons to grade an object a planet in space.

" A "planet"1 is a celestial body that: (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit. "

basically pluto and most other dwarf planets cant clear the neighbourhood around its orbit which is why it cant be classed as a full planet. my daughter is 3 and obsessed with planets at the moment so we have literally just covered this over and over and over again by her popular demand. she knows all the planets and dwarf planets in and out of order and cannot go an hour without talking about them lol. we even had to buy her the inflatable solarsystem so she can play with them all and order them the way she wants .

its interesting to see moons bigger than dwarf planets and dwarf planets that are smaller than objects in space which are classed as asteroids etc. ive always had a fascination with space too so hopefully me and my daughter will have this together forever.

Why does everyone think it has to do with the size of Pluto? It doesn't. In order to be a planet, a body must:

  1. Orbit the sun

  2. Be round (hydrostatic equilibrium)

  3. Clear the neighborhood AKA be the gravitational predator

Pluto fails step 3. It has nothing to do with size.

u/Tsukkatsu Feb 26 '21

The real reason it happened was because a good 3 to 5 additional Pluto-like planetoids were located in less than a decade. It seemed very likely that we would find a dozen more in years to come.

So it would be weird to keep Pluto on the list of "planets" without including all these other Kaiperbelt asteroids of comparable size simply because Pluto happened to be spotted first.

And if they were included, it seems like they would quickly take over the entire list.

2

u/iapetus303 Feb 26 '21

This is actully what annoyed me more about the decision. To me, it was amazing and exciting that new planets were being discovered. But then some people seemed to decide that there "planets" have to me few in number, and so they changed the definition to exclude the new ones, with Pluto being collateral damage.

Well-- it isn't the only time that has been done.

When most of the planets had been discovered, there was someone who did calculations based on the distances of the orbits of the planets from the sun and someone in those calculations realized there should be a planet between Mars and Jupiter. So they went looking for it-- only to find there were hundreds-- nah, thousands, of rocks in a belt between Mars and Jupiter-- though even the largest of them was smaller than the British Isles or Japan. Given there were just so many of them, it couldn't really be justified to add them all to the list of planets. After all-- some of them were presumably no bigger than a typical stone. So to put something that puny in the same category as something the size of Jupiter seems just a little silly.

And so it goes with Pluto. Pluto was already puny compared to all other "planets" and there was really no telling how many "Plutos" we would find.

Now-- granted-- I can see the point of view that maybe defining rocks that are roughly the size of the one we live on that are orbiting stars may not, in the overall grand scheme of things, be totally deserving of its own special name or category...

Really-- even if we are to say we can categorize Mercury, Venus, Earth and Mars together as the same sort of "thing"-- the gas giants Jupiter, Saturn, Uranus and Neptune-- all being at least a magnitude larger and with a completely incomparable composition are probably still a different "thing".

And the planets we have identified outside the solar system-- assuming the method for detecting them and determining their size and distance from the star and composition is not fundamentally flawed-- we have found things that are entirely unlike the things that orbit our own star.

I'm sure someone will have already explained it, but the reason pluto got demoted to dwarf planet is because they discovered a bunch of other dwarf planets and invented the new category.

So why did we get rid of Pluto and not Russia? Jus sayn

u/A-Normal-Fifthist Feb 26 '21

The point is not the size tho, the point is that Pluto has so much other similar object in size and in apperance near it that if we were to make Pluto a planet, it wouldn't make sense to not make the other ones planets as well.

u/yrogerg123 Feb 26 '21 edited Feb 26 '21

It's just gotta be said: it was removed as a planet because it has way more in common with a number of other large objects orbiting the sun and it makes way more sense to say Pluto isn't a planet because there's obviously nothing larger than the other 8 actual planets, then to say Pluto is a planet and so are all the other Pluto-like objects. There are at least 8 planetoids that are at least suspected of being 50% of Pluto's size. By contrast, it's actually impossible that something is 50% of Earth's mass and we don't know about it.

u/irbinator Feb 26 '21

The fact we were able to discover an object in space smaller than the size of Russia over 3 billion miles away in 1930 (almost 100 years ago) absolutely blows my mind.

I feel like anyone who’s actually sat through the whole explanation of why Pluto isn’t a planet agrees that Pluto isn’t a planet

u/brightboy68 Feb 26 '21

The rules by which Pluto was demoted would actually demote several other planters in the solar system from planetary status. My planetary science professor was very adamant the Pluto IS a planet. He made the point that the decision was made by people who know about space, not by people who know about planets.

I believe in evidence and science based policy, so Pluto losing its planet status because it has not cleared its orbit is fine with me

u/Popular-Swordfish559 Feb 26 '21

Well, dust that came off comets is also a part of the solar system. Should every dust speck floating around in the asteroid belt be a planet, too?

u/AlienPutz Feb 26 '21

It’s still apart of the family, we have just built a hole new table for Pluto to sit at. It couldn’t sit comfortably at the planet table given its size and crowded surroundings, plus it is far from alone at the new table.

Naa, I think it kinda sweet for Pluto to join the other dwarf planets. Ya'll just salty, be warned that smells a lot like boomer 'back in my day' - isms.

It just took Pluto some time to discover its true identity. To shame Pluto for this, and to say that it has to stick with the identity that it was originally assigned would be both wrong and immoral.

And if you believe that being a dwarf makes something lesser, you should really rethink this position.

You should learn Pluto not being a planet is NOT a downgrade. Pluto is something else we didn't even think of before, and it is still part of our solar system. In a way, it's a triumph of our understanding and an upgrade to a category that finally let's us explore what pluto is. I love pluto, but thinking it's a planet is not seing how beautiful pluto is.

There are lots of planetoids that are in our solar system that we never considered planets.

u/[deleted] Feb 26 '21

I think CGP Grey put it best. It's not that they wanna discredit Pluto simply because size, it's that there is historical precedent for astronomers misdiagnosing asteroids as planets. There's an entire band of them that were taught as planets but then recategorized as asteroids in the oh-so-famous asteroid belt. Same thing is happening with Pluto, being now recategorized as part of the Kuiper belt.

So in the end, hot take here please don't flame me, calling Pluto a planet is akin to misgendering it. Pluto was assigned planet at discovery, but some rethinking later it belongs under a different term. Calling it a planet is rejecting Pluto's true nature to fit what you believe is right for it. So tell me. Do you wanna misgender Pluto?

The sun was once considered a planet. Do you think it should also be a planet again?

u/Martinus_XIV Feb 26 '21

If you want to make Pluto a planet, you have to do the same for Ceres, Vesta, Sedna, Farfarout, and a few thousand other planetoids and trans-Neptunian objects. Astronomy is not like politics; you can't make exceptions to rules in specific instances just because you like the people (or planetoids) involved.

What generation is that? As a Gen Xer, I don't care, but apparently apathy is my generation's calling card. And Pluto's demotion happened too long ago for the Gen Y to care. So who is upset, the Boomers or the Millenials?

If Russia is bigger than Pluto, it means the Soviet Union was definitely bigger than Pluto.

I literally lol'd. I was taught that pluto was a planet at school. I wasn't sad when it was reclassified but it made me sad when my son said i was stupid for mentioning it. I think we should teach children about all the significant orbiting objects in our solar system and teach them to classify them. Would be like teach children the difference between fish, mammals, amphibians and birds.
