What If Planet 9 Doesn't Exist? 4 Alternative Theories
Vložit
- čas přidán 3. 07. 2024
- For decades, the Planet Nine hypothesis has captured the imagination of astronomers and the general public. This hypothesis suggests the existence of a giant planet, about the diameter of Neptune, that has never been observed and could be in a distant orbit from the Sun beyond Neptune.
The existence of a ninth planet arises to explain certain anomalies observed in the orbits of trans-Neptunian objects (TNOs), particularly in the Kuiper Belt.
However, despite the observations and theoretical models that support its existence, no other planet has yet been detected beyond Neptune's orbit. Not even the most powerful telescopes we have today, such as Hubble and James Webb, or astronomical observatories worldwide, have been able to observe this planet at any time.
This apparent contradiction between the measurements and the lack of evidence for a ninth planet has led many astronomers around the world to ask the most important question.
Could it be that Planet 9 does not exist?
What if all the gravitational anomalies of Kuiper belt objects are due to other previously unknown phenomena?
It turns out that several theories could explain the gravitational anomalies of the Kuiper Belt without the existence of a ninth planet. Do you want to know what they are?
Join us to discover it!
Planet Nine Hypothesis
First, why was the hypothesis that a ninth planet was raised?
The idea that a ninth planet existed beyond Neptune gained prominence in 2016 when astronomers Konstantin Batygin and Michael E. Brown of the California Institute of Technology (Caltech) published a paper in the Astronomical Journal suggesting the existence of a planet with a mass about ten times that of Earth and a very eccentric and distant orbit.

Are we looking for Vulcan 2?
The story of Vulcan is the best example we have of what could be happening to Planet 9. This is a fascinating chapter in nineteenth-century astronomy, reflecting the challenges and errors in the quest to understand the solar system.
Theory 1. Collective Disturbances of Multiple Objects
This theory suggests that anomalies in the orbits of trans-Neptunian objects (TNOs) could be explained by the combined gravitational interactions of many small bodies in the Kuiper Belt and the Oort Cloud rather than a single massive planet, such as the hypothetical Planet Nine.
Theory 2. Influence of the Galaxy and Tidal Forces
This theory proposes that the gravitational influence of the Milky Way can explain anomalies in the orbits of objects (TNOs).
Theory 3. Effects of a Disk of Matter on the Outer Solar System
Another possibility is that a disk of dense, massive material in the outer solar system may influence the orbits of TNOs.
Theory 4. Small Planet or Dwarf Planet Hypothesis
A variation of the Planet Nine theory is that instead of a giant planet, there could be a minor planet or a series of dwarf planets beyond Neptune that could be causing the perturbations.

Great video and information !
Thank you!
I’m lucky enough to have three granddaughters that have grown up with eight planets in our solar system.
I tell them about the days when I was a child and we had nine planets.
They are nice and pretend to care. I love those kids.
We still have 9 planets
@@fairamir1 No we don’t unless you want to add 200+ more to the Solar System. 😂
@@elijahsmall5873 Nope...just stop trying to treat Pluto as a step child
@@elijahsmall5873 ,Your Too Young,And Acting Like You Know Everything..What A Fool
@@fairamir1 Nobody is treating Pluto like a “step child”. Pluto doesn’t give a damn what we call it. If you want to disagree with the people at IAU that’s fine but you can’t say the IAU says Pluto is a planet because that’s factually incorrect. lol
Is it possible that "Planet 9" was ejected from the solar system long ago? many millions/billions of tears? with what we are seeing as the effects that are left over from the "Planet 9" having been here. Does "Planet 9" still have to be in the solar system to have the effects we are seeing currently?
Yes , but its like with Dyson sphers emitts infrared light until they find out they dont need to emitt infrared light and are thus not visible for us ." They" push agenda like this since it fits them or benefit from them ( there is recennty development on infra red solarpanels).- Anton Petrov has a video on a star that came close to the sun 70 000 years ago and could have ejected Planet 9 or sent it hurtling toward us or it could been crashed into that star or its planets . Question is how long would it take to the rest of the objects in kuipers belt or ort cloud to resume their own made orbits without the influence of planet 9 if it maybe were ejected long before that -millions of years ago
Not really. Imagine if the sun suddenly disappeared, will earth remain in its current orbit for millions or billions of years? Once the space-time distortion (existence of the sun or the 9th planet) is gone, surrounding objects will need to settle into a new stable orbit and we won't be able to observe those "anomalies".
It isn't as simple as it sounds because it needs a lot of planning and resources. Thanks for your comment!
@@InsaneCuriosity you have to watch other youtubers vidoes on the matter and not use a bought script and think for yourself
@@dEath_kNIghT383 Uhhhh, wut? If the sun suddenly disappeared, Earth would no longer be orbiting *anything* and would fly off into interstellar space, as would everything else in the solar system (which would fly apart at speeds even Jupiter could never overcome). If that was what you meant you didn't say it very clearly.
Planet 9 exists. Its called Pluto.
Pluto is my favorite space object.
I still consider it a planet.
Great job team 👏
Thank you 🙌
I saw another hypothesis saying the 9th planet is actually a primordial black hole. Can't remember where I read this but it's an interesting hypothesis -- a mini black hole with a mass similar to Neptune.
Problem is, we can't even prove that primordial black holes even exist let alone that one of them is orbiting the sun. The entire idea seems like a needless complication to me unless and until primordial black holes are proven to actually exist at all in the modern era.
@jasontoddman7265 which part of "hypothesis" you don't understand? A proven thing is NOT a hypothesis.
@@dEath_kNIghT383 Where did I say it was? And why are you talking like I contradicted or even disagreed with you? I was agreeing that not only are primordial black holes a hypothesis, but that it will likely remain so for many decades or centuries to come because of the enormous difficulty involved with observing the things individually even if interstellar space is *saturated* with them.
One of tue most important questions to ask in science when proposing a hypothesis. Could it be anything else?
If Vulcan does not exist, where did Mr Spock come from? 😂
Pluto
We will probably never know: given the distances and size involved we will likely never be able to map and track all the items out there, which means even hundreds of years from now astronomers will be looking for a "Planet 9"
And since most of what we know about space is just guesswork backed up by who can write the better paper and has a stronger reputation, there will be theories coming in and out of vogue as to whether it exists or not.
I’m fairly sure Pluto is classified as a dwarf planet !
Appearently it doesnt reflect any light so most likely it does not have an atmosphere ! A small rogue black hole is plausible
The ninth planet is Pluto.....in my opinion it is not a dwarf planet but a planet and should be recognized as one.
Agreed
Pluto is *still* Planet 9.
The mysterious, missing planet is "Planet X", of course.
Good point about Pluto! Thanks for your comment!
Could it be that multiple of these theories are possible, and still have a less massive smaller planet 9 that's difficult to locate?
I think the people who are researching this are a lot more intelligent and richer than I am. But, keep me posted. hopefully, I'm still alive when they figure this out.
I want to believe it's there, but who knows?
I miss the time that we had thought a small dwarf planet was called Pluto and was considered for a time to had been the ninth planet.
You mean what if Pluto didnt exist? That sounds dumb.
The mysterious, missing planet is "Planet X", of course.
I like this topic. I feel like we can be excited about spending time looking for intelligent life on other planets. I say this with the utmost respect and I hope that one day we will be proven right. However, currently, the only evidence of intelligent life that we know of in the Universe and that is us. We have come so far in such a short period of time and I truly believe it will take us some time to find another form of intelligent life, equal or better than ours. Of course, this is based on the fact that we only get to see the rest of the universe for a very short period of time. Taking into account the age of the universe and the incredible global events that have occurred over the past few billion years, I would say that intelligent life will be very rare in the universe. However, I strongly believe that complex life forms certainly exist and are probably abundant.
I wonder if the issue is a situation of limited data. Is the alignment real, or just a matter of too few data points? Does the evidence even support the possibility of a ninth planet?
That issue aside: if the ninth planet does exist and is discovered, will that force the IAU to reconsider the current definition of planet or offer a near confirmation of the definition?
Great questions! The alignment could be due to limited data, and more observations are needed to confirm any theories. If Planet 9 is found, it might lead to discussions about the definition of a planet. The IAU would have to consider new evidence, which could either reinforce or change the current criteria.
I remember someone thinking we were a binary star system with a brown dwarf? Is that possible?
Earths twin star is located roughly 184 light-years away, it's called HD 186302,

the sun is a big bright hottery star...
from mercury to pluto are still 9 planets
All great theories. Maybe one of them is in fact correct?? Then again, maybe it’s something we haven’t discovered yet. Can’t wait to see where the scientific method leads us!
Planet 9 is called Pluto
Maybe according to the classifications you’ve constructed but not to the current classifications of the IAU.
@@elijahsmall5873because they are lazy
I still say they're looking in the wrong spot.
Everyone seems to be looking along the orbital plane at +/-5°, but what if the orbit is similar to that of Pluto, but even more so at an orbital plane differential of 35-75°?
Planet 9 existed. It was called Pluto :)
Criteria for being a planet:
1) Must orbit the Sun✅
2) Must have sufficient gravity to force yourself into a spherical or round shape✅
3) Must have cleared your orbit of other objects❌
Pluto meets the first two but fails to meet the last therefore, Pluto’s not a planet according to our current classifications. It is a dwarf planet just like all the 200+ objects like it in the Kuiper Belt and in the asteroid belt between Mars and Jupiter. If Pluto’s a planet then our Solar System now has 200+ more planets.
@@elijahsmall5873 So what is planet 9? And how did you know pluto didn't clear an orbit?
@@tahirahmad9645 Planet 9 is a hypothetical ninth planet in our outer solar system responsible for the strange clustering of orbits for the trans-Neptunian objects (bodies beyond Neptune that orbit our Sun). Basically its gravitational effects could explain these weird findings if it were real.
@@tahirahmad9645 We can tell Pluto hasn’t cleared its orbit because we can see that they are things in the way and it literally crosses over into the orbit of Neptune.
@@elijahsmall5873criteria made up by people who wanted to exclude Pluto be design.
I am with the planet 9 is Pluto camp.
If that is the case, I would submit that it would be the tenth planet not the ninth. Ceres would be a planet as well.
NO! Planet 9 is real, I can feel it in my heart
Is it possible that “planet 9” was a rogue planet that flew by and disturbed the orbits of the TNO’s? If so, then it isn’t there anymore and we’ll probably never know what it looked like. I don’t know op if the orbits of the TNO’s would return to an undisturbed, neutral state. Just a thought.
Some scientists think Planet 9 could have been a rogue planet that disturbed the orbits of TNOs and then moved on, but it would take a long time for their orbits to go back to normal. Thanks for sharing your thoughts!
Maybe there is a plant between the Sun & the next closet star 🌟- Proxima Centuri.
They say it does exist but there something blocking it from being detected cause if the gravity it pulls but who knows
I find it hilarious that the same people who vehemently believe in aliens are the same ones who will challenge the findings of two very qualified scientist the existence of the 9th planet 😅😅😅
I have never believed the existence of planet 9 based on the evidences provided thus far!
So what do you live on?
I think you mean ...
Engine, Engine num'9.😜..
I am nowhere close to having sufficient astronomical knowledge as good as even this video's producer, let alone those Caltech people. Nevertheless, if we just go by simply logic, what is now observed is that those clustered dwarf planets are in the way they are, because there is something of similar mass at where Planet 9 (P9) is proposed to be. The alternative theories are that instead of a massive P9, it's instead a few other clustered dwarfs or a disc that add up to the same mass that caused it. At the end of the day, if something as massive as P9 at that distance is too far to be observed by modern day technology, it's even harder for something smaller to be seen. In the end, I would just conclude this way - the absence of evidence is not the evidence of absence, but equally, just because there is an absence of evidence to show something exists doesn't mean it definitely exists (i.e. there are many possibilities out there).
Hi , I'm 5th Gas Giant
❤what if planet 9 is a small black hole? That's why it's hard to detect.❤
It could be a possibility! Thanks for watching!
It actually does exist planet x news actually has pictures from the sdo i think thats his name
Yeah, there's always new evidence popping up. Thanks for sharing that info!
Planet 20.
Just say it is a dark matter body. No one can prove you wrong because dark matter is whatever it is needed and wherever it is needed to explain gravitational anomalies. Dark matter never shows up in inconvenient places like particle accelerators or laboratories, so a dark matter hypothesis can never be proven wrong. Problem solved.
Indeed Dark Matter does act like a placeholder which is kind of self defining. It does have some level of trouble in the area of falsifiability which is one key test to move from hypothesis to theory.
Decades?? Ugh
Pluto is planet 9, come up with another name.
That planet is coming, it'll be in view soon, just know the kingdom of heaven is near.
It could be dark matter, or a primordial black hole captured by our sun long time ago.
Yeah Planet 9 doesn't exist there is no Planet 9 unless you consider Pluto a planet again then yes Pluto is 9
Pluto will and has always been a planet for me
THen Planet 9 was discovered beyond Pluto orbit
The answer is in a youtube video called answers of an alien from andromeda, video #71.
@@Superstorm50 Pluto is smaller than our own moon
If Pluto is planet 9 then we need to give planetary status to Eris and Ceres along with the other dwarf planets I think. Although Pluto is the largest and has 5 moons too, so maybe it deserves reconsideration?
Here’s a theory maybe it doesn’t exist
It's definitely possible that Planet 9 might not exist, which is why we're exploring all these alternative ideas.
Odd how the search for planet nine parallels the myth of Nibiru
*5 sigma* is enough evidence that GP5 indeed exists
it not existing has the same improbability like winning in the lottery!
(gp5 = giant planet five)
What if planet 9 is a DJ like your mums ? Cool "theory" right?

Pluto is planet 9. what you're looking for is planet 10 or "X".
Before anyone says it...yes pluto IS A PLANET....and nothing you say or do will change my mind. Nature defines planets. Not humanity.
But if it stays yes, but it is in a class of itself, it is also not only planet 9. It is also the only binary planet. We got to planet system. Week got put on Sharon or a binary plan. It? That's the best easiest way to look at it. So we've already got planet 9 and 10. They're looking for number 11.
Actually nature doesn’t define anything as anything. It is us humans who give labels to stuff and categorize everything because it is useful for us to do so. The universe couldn’t give two flying hoots how we categorize and organized it. However, our current definition of a planet says Pluto isn’t one but a dwarf planet.
Criteria for being a planet:
1) Must orbit the Sun
2) Must have sufficient gravity to form yourself into a sphere or round shape
3) Must be able to clear your orbit of other objects
Pluto meets the first two but fails to meet the last so it is not a planet according to our current classifications. It is a dwarf planet just like all the 200+ objects like it in the Kuiper Belt and in the asteroid belt between Mars and Jupiter. If Pluto’s a planet then the Solar System now has to have 200+ more planets. Try teaching that to children in school.
Also, there already is a search for the hypothetical “planet 10” or “X” in addition to the search for “planet 9”.

@@elijahsmall5873exactly. It was the laziness of European (excuse me, "international") astronomers that led that criteria. I remember when Eris was discovered, it was considered planet 10.
