When NASA's New Horizons spacecraft finally reached Pluto and sent back the first images of the far-flung world, we saw something that absolutely blew our minds. For decades, Pluto had been a planet of paradoxes. Once considered the ninth planet in our solar system, it had been reclassified, debated, and wondered about. The object had remained a blurry dot even in our most powerful telescopes. But now, after more than 80 years of its discovery, we had the first close-up pictures of Pluto. The spacecraft showed us a Pluto filled with geological features that indicated not just a history of activity but the possibility of ongoing dynamism. Towering Mountains, deep valleys, and vast plains suggested a world in the process of changing, not a fossilized relic from the past.
But the most surprising discovery was the strong evidence of a subsurface ocean concealed beneath layers of ice. This finding didn't just make us reconsider Pluto; it threw open new doors of possibility for the existence of life beyond Earth. If a so-called 'dead' planet, at the far reaches of our solar system, could harbor an ocean, what else might we find as we venture deeper into the cosmos? - Věda a technologie
So, should Pluto be reclassified as a planet, given the discoveries made by the New Horizons spacecraft? What do you think about it?
Yes definitely. It should never have been declassified as a planet.
What are the rules by which Celestial objects are described as "Planets", "Dwarf Planets", "Moons", "Asteroids", "Comets", or anything else I may have missed.?
.
Does Pluto having an underground Ocean change this.? If so, would that then potentially reclassify other "Celestial objects" currently considered "Moon's".? If not, why.?
Planet.
Pluto is a Dwarf Planet. The reason why it’s classified as a Dwarf Planet and not a planet is because though it orbits the sun like the rest of the planets, it’s not as massive as the other planets. Pluto is smaller than both the planet Mercury and our moon. That’s why it’s called a DWARF Planet.
What difference does this make? Why would it ever make a difference? If it cannot clear its own orbit, it is not a planet.
It’s always been a planet to me 🥲
Pluto will be always a Planet for us. 🤍
It will always be a planet to me!
Start playing the sad but beautiful music.

@@KleoptraI swear to g-
Pluto is perhaps the prettiest marble in our system. Just beautiful and mysterious.
For me Pluto has always been a planet, and always will be. Not only because it was a planet during my youth and many years after, but also because I once had the pleasure of meeting its discoverer!
you met Wa jung from 400 BC
@@serronserron1320 or, more likely, Clyde Tombaugh 1906-1997
I agree. I always thought Pluto should NOT have been reclassified to smaller planet or "not a planet". In school [50s & 60s] we were taught Pluto IS a planet. I also agree with that. It SHOULD be reclassified to "planet" again.
Old
No matter what it is, if it is round, orbit the sun, it should be a planet in our solar system.
@@Tom-ck3ioI'm 32 and was taught the same till niel did his magic
@@bangrojai4868it is a planet, it's never not been a planet. It's a planet that's classified based on its characteristics like how earth is a small rocky planet and Jupiter is a gas giant. We don't think of earth as not a planet because it has a different classification than Jupiter do we? Don't you think it's useful to be able to know what the characteristics of something are just by hearing the classification? Otherwise we'd have to go into detail all the time. Like if an alien came down and said it lives on a planet you could respond by saying "wow, how do you live on a gas giant?" because it didn't give you a planet type to work with. It's like introducing yourself as a life form instead of being specific and saying you are a human. Or telling someone you drive a vehicle. Well what kind of vehicle, there are many types and they can be very different but they are all vehicles yes?
YES Pluto is a planet, a planet with a big heart ❤️.
Hell yeah!!! Make Pluto Planet Again!!!!
Team Pluto❤
With beautiful white heart. 🤍
Since I was a child and was able to study science Pluto is a planet to me.
Never hasn't been a planet, study science more.
It's always been a planet to a LOT of people.
It's still a planet
it's just been re classified as a dwarf planet due to it's small size.
just as we have giant size planets
The earth has been “flat” to a lot of people to 😂
@@DavidPierceCHTIt's also hollow. In a dome. And there are penguins with laser pistols guarding a Predator pyramid in the antartic.
Just ask a Trumper.
They will believe anything.
@@DavidPierceCHTPluto goes through Neptune’s orbit, so Neptune isn’t a planet anymore.
Jupiter also hasn’t cleared its orbit entirely, so that meAns it’s not a planet either (or it was Saturn I don’t remember)
Definitely still a planet in my mind… i take Science, and Astronomy quite seriously; and I think they really jumped the gun by changing its classification. The change will probably lead to less primary curriculum on Pluto, and grouping it with other “dwarf planets,” in textbooks. That would be a shame. I feel like we need less of a focus on Mars, and more focus on the outer solar system.
Tbf Mars is much closer to us and is (relatively) more hospitable for humans
Mars is much easier for us to send humans too
I feel like we should focus on Mars before we get to the outer planets because Mars is believed to once have oceans, and if that’s true, then it’s possible that it once contained life. It might have been only microbial though since Mars didn’t last that long. We should also focus on Venus too because these are our next door neighbors.
No. There have to be hierarchies to this kind of thing. Astronomy isn't interested in your feelings on the matter.
@Kleoptra are dwarf people not people?
LET'S GO PLUTO!
Question is, will it want to be a planet after all the humiliation?
LMFAO .... That is about the funniest comment I have read in a long time. Good One @transputin ! 🤣👏
Everything is alive. Every galaxy and every molecule. The Universe is a living one. And I never took Pluto off of the planet list.
No one else did either, it's always been a planet.
I knew it. Planet status reinstated in my eyes
For Indians, 9 planets from ages as per Hindu mythology
@@markmccullough5873no they didn't. You can read all the actual translated Sumerian writings if you actually want to learn.

@@patriciamoraled2004who invented 0? Your dad?
we have to remember that our oceans strived too under the ice when our planet was completely covered in ice in one of the Earth extinctions
Never underestimate Pluto.
Awesome episode, loved it! And how timely; was just mentioning about how I simply cannot accept Pluto as a Dwarf Planet, when it is so dynamic etc... this video was posted withing 30 minutes of my comment, so I am smug, lol
It would be a joyous comeback if IAU considers Pluto to be a planet again.🥰 Really liked this episode! 👍👏❤️
Pluto is a planet - A DWARF PLANET - an entirely new classification was bought in due to what was found about Pluto in the first place, and other bodies. So it can not be renamed a Planet.
So, it's a planet then 🤷🏼♂️
@@rianmacdonald9454It is a planet, just not a primary. It does not have to be a primary to reqain the position of 9th again. Our system is comprised of two types of planet and other than the correct classification as a Kuiper belt dwarf planet (binary actually) other criteria for classification are dubious at best.
It never changed from being a planet. Just some idiot with a pencil says it's not. It's a planet.
It won't be returned to being a full planet. It is in the same situation as Ceres was when other asteroids began being discovered. Once it became clear it was one of many such objects, just the largest, it was no longer considered a planet. You only don't know that because it happened before you were born.
It’s been always a planet. 😅
Well, finally it got back the respect it was given 100 years earlier by its discovery.🤔
I would think that Charon's relative size, closeness and speed would create tidal forces that would contribute to Pluto's interior heating.
I think charons gravitational influence has a huge part in plutos possible ocean.
Very plausible theory.
💯
Pluto should be reclassified as a planet, it was declassified without hardly anything being known about it, now it is proven to be far more than just a desolate rock, it has all the characteristics of a planet, it will always be a planet to me
Raj: Sheldon, I want you to meet Neil deGrasse Tyson from the Hayden Planetarium in New York.
Sheldon Cooper : I'm quite familiar with Dr. Tyson. He's responsible for the demotion of Pluto from planetary status. I liked Pluto. Ergo, I do not like you.
🤣😂😆
I grew up and was educated, like so many people, with 9 planets in the Solar System. In 2006 the IAU gave that controversial "gift" to both professionals and amateurs of astronomy... However, they justified the decision. If we change the criterion again, we will probably have to accept the idea of a system not with 9, but with dozens of planets, among them Ceres itself, which orbits a star, has reached hydrostatic equilibrium and has recently been discovered geological activity. I don't know if it would be time to renew all the textbooks again...
So be it.
Pluto will always be classed as a planet to me
It should be classified as not just a planet(although ive always known it as a planet and it always will be) but a binary planet thanks ti Charon. Our first binary planet of the solar system
I guess the fact that the baricenter between Pluto & Charon was a big factor in its reclassification & the reason it was reclassified AS a dwarf planet.
The reclassification of Pluto back TO a planet would put closer-to-us bodies like Ceres (in the asteroid belt) into that classification🤔
The classifications regarded in smaller bodies in our solar system is quite vague when dwarf planets are taken into consideration.
Kinda flusters this nerd, too; because I remember Pluto being considered a planet🤔🤓
Where there's water, there's life.
In my mind it was never declassified. F for scientists.
And your degree in Astronomy comes from where?
It was reclassified, it was never not a planet except to people that didn't understand what was happening.
If the IAU is worried about all the dwarf planets similar to Pluto, why not just state "The original nine planets were Mercury...Pluto. Further discoveries of dwarf planets similar to Pluto (Ceres, Makemake, etc.) has expanded the number of possible planets." That way you include the original nine plus note the idea of dwarf planets, more planets of the solar system, new names for students to be intrigued by, and the idea that science is changing, not always the same. I know that when I was a youngster such would have compelled me to get into astronomy (which I considered once entering college).
I don't want it to be reclassified. I want to visit there one day, and planet status would only cause more tourism. (just kidding; I Love Pluto no matter what its status! In fact, I relish the enigma....)
Really well explained and fascinating findings. For sure this gives Pluto a special places in our home, pretty much making up the suite of diversity in Sol. Bring Pluto back to the forefront, if not for science but for our neighborly friend that is considerate enough to leave us Humans an ocean of water when we evolve outwards passing by Pluto in the near future.
Planet. Also a cartoon dog.
Yes on both. 🐕🐕🐕🐕
Ultimately, it doesn't matter what the IAU thinks.
Thank you for knowing the singular form of phenomena, and using it correctly. 🌹
IIRC, there are many more objects like Pluto that would then have to be called planets as well, and that would be far worse than just going from 9 to 8.
Can’t count past 9 huh?
@@oilersridersbluejays LOL. u wanna teach millions of students the names of the 200+ estimated pluto-like "planets" as they're discovered?
Pluto have always remained a planet for me.
Pluto was always a planet, just in a new category, but still a planet
Pluto IS a planet. PERIOD!
SIZE does matter when it comes to planets. For the record I was in favor of calling smaller planet like objects "planetesimals". Its a classification, not a death sentence. What would be so bad about calling Pluto a planetesimal?
Yes! Always been a planet to me as well, would be so happy to see them start calling it one again too😎. Would make it a very interesting story to tell 100 years from now too.
Pluto has always been a planet. Recognize its rightful place, and demote Neil deGrasse Tyson pretending to be a scientist.
I'm starting a campaign for equal recognition of dwarf planets and Pluto will be its charismatic champion.
Pluto should be a planet!
@Kleoptra draf planet? Sound as absurd as a dwarf planet.
Nice video 👍
As 80's kid back on 80's what we studied about our solar system's Pluto is 9 planet ... The kuiper belt was not even discovered ... Pluto you're still a planet for me 😊
So I'm a firm believer that Celsius is a construction of heat being pulled from the opposite direction meaning the orchestration of minerals has capability being pulled and lifted inside out from a different rotation of gravity
Celsius is a more sensible measurement of temperature.
@@oilersridersbluejays why do you think temperature though you ever thought about pressures rotation or even possibly like Newton sin as an apple falls goes up must come down but it does it drop inward out pressure or outward in pressure
Yes, reinstate Pluto's planethood!
Pluto will remain a Planet in my book.
Can you put the sources in your video description?
Pluto used to be a planet, then scientists became a joke. It turns out Pluto was always a planet, and scientists are still a joke.
No one ever said it wasn't a planet, except people who didn't understand what happened.
Pluto's a planet it will always be a planet no matter what scientist say to me Long live Pluto
I almost didn't realize this was a Sunday Discovery Series, I am so used to your typical intro, with the questions being asked.
It is really an amazing discovery by Horizons spacecraft! There are about 6-7 total oceans, open or hidden below the surfaces, in our solar systems. It might existing on Pluto like planet or other moons like, Europa, Titan, Enceladus, Ganymede or Neptune etc.
Neptune?
Pluto is a dwarf planet, and if I learned anything from my reading, it's that dwarves sometimes dig too greedily and too deep! 😃
This is science in action. Theories change as new information is brought forward, debated, and made sense of.
We love you Pluto 🤍🤍🤍✨✨✨
Pluto is absolutely fascinating. It would be incredible if we had a satellite around Pluto, to study its surface and make new discoveries about our little planet with the biggest heart.
I've never stopped calling Pluto a Planet...
When asked to name the planets, after naming the others I would always end by saying "Oh yeah & Pluto, Even tho' NASA says it's not".... Ha 😃
I definitely believe scientists need to return Pluto's status as being a planet. It should never have been removed from the list in the first place.
Maybe it should be considered, BUT if it was then other several similar Dwarf planets could be too, and if that's the case there would be MANY
That is why the classification of DWARF PLANET was bought in.
@rianmacdonald9454 so basically you are saying they changed Pluto to a “dwarf planet” because the thought of having other planets like Eris (et al) is offensive to a small group of scientists and people cannot fathom more than 9 planets.
@@oilersridersbluejays no, I'm just stating that there are already over 40 Dwarf planets that have been discovered so far in our solar system. If we decide that Pluto needs to be reclassified as a planet, then that gives room for the other ones to follow suit. It doesn't meet all of the criteria anyway
Arbitrary criteria. Those criteria were not stated until they wanted to demote Pluto.
Lol watch Pluto end up being exactly like on Rick and Morty with little aliens 🤣
Pluto has always been a planet. It totally meets the definition and always has.
I was Insulted when Pluto was declassified. Esp since we knew it was active when it was.... IT SHOULD be reclassified asap.
I wholeheartedly agree that Pluto should be classified as a true planet as it always has been and not like the idiot who called it a dwarf planet just because they say it hasn't cleared out his orbit sure seems I can clear it out to me there is no recent impacts that we can tell and if there was that's motions of clearing out your surroundings for planet
Wouldn’t it be ironic if we ended up inhabiting Pluto !
I like Pluto. It's still a planet to me. it's so cool that it has a heart shape on it's surface. ❤
Poor Pluto doesn't even know some aliens from earth judging him .😂
My son of 6, while doing a 150 piece puzzle of our solar system: Dad, is Jupiter the biggest planet in the world?
Pluto was a planet, and it is a planet and it will be a planet. Let us all agree that we have never known enough. We don't even know what is enough when it comes to space exploration
We should just continue to explore...
Pluto, 1) orbits the sun 2) has an atmosphere 3) has a system of moons (Charon) 4) has an ocean.
Pluto will always be a planet. I used to live there before moving to the US.
First?
Never been this early. Obsessed with anything astronomy ❤ ✨
Your a star
Want a cookie?
This was presented well.
For 90s kids Pluto will always be our 9th planet.
Pluto IS a planet!
And an awesome one, too!
This proves every scientist that argued Pluto wasn’t a planet was WRONG !
It's about freaking time!
Pluto: the fk girl you want me or nah
It should be reclassified as a planet, period.
Scorpios never listened to that Pluto isnt a planet nonsense.
Maybe the next world will be Jupiter as the next star/Sun, while the other gas planets such as Saturn, Uranus, and Neptune will appear as the front-line planets of Pluto that can be habitable for the next civilization of future lives.
I agree, Pluto is a planet. Similarly, if Eris and Makemake possess oceans and other characteristics that qualify them as distinct celestial bodies, then they should also be classified as planets.
Your Mom thought I was Big Enough.
- Pluto
Pluto is and always will be the 9th identified planet.
Yes, IAU were stupid to declassify it
Upon closer inspection, they are indeed building another car wash.
I just ignore people who say Pluto isn't a planet. Just like I ignore the people who write bad Star Wars stories and call it canon. There's only three legitimate Star Wars movies, and nine planets in my world.
Most important point:
Whether Pluto is recognised as planet or not it doesn't matter to Pluto. It will revolve around the sun and will in the future and Pluto doesn't care about those nonsense....
Pluto The god of Hell, it's amazing celestial with beautiful white heart, I've heared much of interesting stories from Pluto like whale on Pluto an ocean on Pluto is good reason to believe there will be a whale on Pluto. Since 2006 Pluto haven't been a planet anymore because it's size is too small BUT in my heart Pluto will always be a ninth planet of our solar system. 🌠🌍🚀👨🏻🚀👩🏾🚀🧑🏼🚀🌑☀️🛰🛸👽👾🪐🪐🪐🪐🪐🪐🪐🪐🌌
Pluto will always be a planet to me, It even has water
Pluto never stopped being a planet as far as I am concerned anyway. Its effect in our solar system is not insignificant, especially in tandem with its moon but there you go. Big heads got it wrong.
Was taught it was a planet, never changed my mind
5'15" to 5'19" says, quote: "The vibrational energy of a molecule depends on its temperature." Correct me if I'm wrong, but doesn't the temperature depend on the vibrational energy of a molecule and not the other way around?
Yes I think it should be a planet again!
We didn't even know it existed for sure 50 years ago. How would we know what's usual there?
I never removed Pluto from my planet list ❤
Just because a small group of influential IAU members called a quicky meeting at a oversea scientific conference unbeknown to the vast majority of voting members back in 2006 and jammed this demoting of planet Pluto for their own reasons shouldn't stand in the way of having a honest and open discussion about reclassifying Pluto to it's pervious listing as a full planet status with all the new information we've gained because of the close flyby in 2016, if the full membership of IAU choose not to change Pluto's status then so be it but at least it because of a true majority vote.
We need RECLASSIFIED PLUTO
because We know about Pluto back story
