- Why Planets Orbit in the Same Plane!
We live in a 3D space, but have you ever wondered why our Solar System is always presented in a 2D disc shape? Well, that’s what we’re going to explore, in today’s episode!

What’s the most popular elementary school project you can think of? Seeds grown from paper? The foam volcano?
Whatever it is, I bet that if I ask you to make a list, one of the items that would be on the top of it will be a model of the Solar System.
If you would recall, these models are basically concentric circles with balls placed somewhere on the circles’ circumferences. The balls represent the planets, while the circles represent the orbits.
Of course, you wouldn’t tune in to this episode if the answers were that easy, would you? Despite being counterintuitive, the elementary science fair model of the Solar System is actually as close to reality as it could get.
I know what you think: but that doesn’t make sense! We have a three dimensional space, so naturally, we can expect that every structure in the universe would be in 3D too!
Now, I’m not saying that logic isn’t right. It does make sense that if we are in 3D space, then we expect 3D structures. For instance, some stars could experience an extremely strong influence of gravity causing them to collect together and form a spherical structure that are called globular clusters. They’re a common sight in the universe. In fact, in our very own Milky Way galaxy alone, we are bound to find around 150 of these stellar clusters. But they’re not the star of the show today.
This is all too weird, right? With all the freedom of motion they have, with all the space that is available for them to move about, a lot of heavenly bodies seem to favor moving in a very confined manner. But how and why exactly does this happen?
Well, to be able to understand how motion in the universe ends up this way, or at least in the Solar System, we need to recall two important concepts in physics. First, we need to re-learn angular momentum. I know, a lot of you our viewers have a pretty strong grasp of a lot of topics in Physics, but we here in the channel want to invite more and more people to be interested in science! So, for their sake, I’ll make a brief walkthrough of what that is.
Second, we need to recall how our very own Solar System was formed: around five billion years ago, back when the Sun wasn’t even a star yet.
Ready? Okay, so here it goes.
So, angular momentum first.
If you know linear momentum, then, angular momentum wouldn’t be too hard to grasp. Linear momentum is the tendency of an object to move in a straight line, by that logic, we can say that angular momentum is the tendency of an object to rotate.
I hope you’re not lost so far. Trust me, learning this is really important in understanding the main goal of the video.
Now, there are two most fundamentally conserved quantities of motion in the universe. On one hand, we have energy and then momentum on the other. By this logic, we can derive that all momenta are conserved. Even the angular one.
So, okay, angular or rotational momentum is conserved. What does that imply?
Say for example, you have a top that’s spinning perpetually. It doesn’t stop, it just keeps spinning and spinning, so you can perform measurements on it anyway you like. Now, say for instance, you measure the angular momentum of this spinner at one time. After doing the task, you felt hungry, so you came out for a long lunch, then came back and measured it again. By conservation laws, you ought to get the about same value for angular momentum as you did earlier.
Angular momentum depends on two factors: first, the distribution of mass in the spinning object; and second, how fast this object spins. Let’s relate that with rotational momentum’s need to be conserved all the time.
Since the value of angular momentum is constant because of conservation laws, whatever change in one factor, the other has to compensate. For instance, if the distribution of mass becomes less, say for example, the volume of this object decreases, then, the rotation has to increase. You can see how this works in ice skaters spinning faster when they draw their hands closer to their bodies.
Can you piece it together now? The blob that was the cloud of particles earlied becomes flatter and flatter, and voila! We have a flat protocloud disc !

The best part about this channel is they encourage u to hit dislike not only like to further improve themselves. That's how u know they value your opinion instead of just throwing content for views. Support this channel.
In that regard, I would advise any who do hit dislike (haven't hit either yet myself since I am only a few seconds in) to post as to why you disliked it. One can not fix problems or improve if they do not know there is a problem.
@@nowthatsjustducky facts! Must say I only hit the like button here but there was on video I disliked one bit of their content but not enough to hit dislike.
Here’s a start at an explanation of how I understand it all working... (1) when something is spinning, that spin will become faster and more visible as the size of the spinning thing shrinks-as when a spinning figure skater pulls in their arms; (2) a cloud of randomly moving cosmic gas and dust will, by chance, typically have some nonzero net rotation/spin (with an axis pointed in some random direction); (3) if for some reason there is a place in space where there is a higher density of dust and gas, its self-gravity will tend to make it collapse, so that the cloud of dust and gas gets smaller and denser; (4) as the cloud gets more compact, the net rotation/spin will become faster and more pronounced; (5) some things won’t initially be rotating/spinning in the same direction as everything else, but as the cloud gets denser, collisions between particles will lead to the motion becoming more uniform, with everything more or less spinning around the same axis; (6) the combination of gravitational attraction, spinning, and collisions, will tend to lead the cloud of material to form a spinning disk shape; (7) within that spinning disk of materials, areas of unusually high density will further collapse (under the influence of gravity) to form stars (if the mass is high) or planets (if the mass is lower). This is, more or less, the way that both galaxies and solar systems tend to form. (In the case of galaxies, other dynamics can lead to some galaxies not looking like spinning disks). I hope this explanation is helpful to someone. [Copied from a nested reply I offered; I thought sharing this as a top-level comment might be helpful.]
I’ve got a physics Ph.D. So, I understand enough to know that this video is more confusing than helpful. It says a lot of things in vague, confusing ways. It may “seem smart” to people who don’t know enough to know they are being bombarded with unnecessarily confusing, imprecise statements that offer only an illusion of teaching.
So why didn't you give a proper answer?
Dude are you one of these people that has a Ph. D. But has no common sense? I enjoy his videos. Don't hate. And I just happen to be very intelligent myself. Intelligent enough not to hate. I don't have a Ph. D. But I do have more than one degree. Atmosperic science and astronomy. I also happen to be an Eagle scout. And one of the few to ever score a perfect on the hiset pretest. And graduated top of my class on the hiset and hopeworks courses. As well as being one of the few to graduate both courses simultaneously. And I also have certification as an HIV/STI/Drug/safe sex educator. I do have a fair understing of mathematics/physics and medicine. Amongst other things. Normally it's the person that is hating that doesn't have a true understanding of the universe.
Dude learn to see the whole picture. Instead of putting someone down. Be nice and help to explain it. You can do that without sounding like an azzhole. Lol. Love not hate.
@@ufosandunusualevents6637 I'm sorry my comment sounded like "hating" to you. I was partly trying to reassure anyone who thinks they don't understand what is being said in the video that it doesn't mean they are stupid -- the ideas are just not being explained nearly as well as they could be. It makes sense to me that you, as someone with some degree of understanding, could make some sense out of, and enjoy, what the narrator is saying. I just struggle to imagine how someone who didn't understand things could come to really understand, based on what was being said. I'm glad you, and presumably some others, enjoy it. Different things work for different people.
Guilt free White man!! Thanks for inviting me to express in a way some might find more constructive. Pictures would help. But here’s a start... (1) when something is spinning, that spin will become faster and more visible as the size of the spinning thing shrinks-as when a spinning figure skater pulls in their arms; (2) a cloud of randomly moving cosmic gas and dust will, by chance, typically have some nonzero net rotation/spin (with an axis pointed in some random direction); (3) if for some reason there is a place in space where there is a higher density of dust and gas, its self-gravity will tend to make it collapse, so that the cloud of dust and gas gets smaller and denser; (4) as the cloud gets more compact, the net rotation/spin will become faster and more pronounced; (5) some things won’t initially be rotating/spinning in the same direction as everything else, but as the cloud gets denser, collisions between particles will lead to the motion becoming more uniform, with everything more or less spinning around the same axis; (6) the combination of gravitational attraction, spinning, and collisions, will tend to lead the cloud of material to form a spinning disk shape; (7) within that spinning disk of materials, areas of unusually high density will further collapse (under the influence of gravity) to form stars (if the mass is high) or planets (if the mass is lower).

I hope this explanation is helpful to someone.
Love u guys, no politics, no pessimistic energy, just pure beautiful educational content.
Considering what we've managed to discover so far without physically going there, it wouldn't surprise me if there's cosmic newbies still to winkle out with our sheer inquisitiveness. Great video👍
I do believe that everything in the universe has a double or maybe even a triple of the same thing, when considering that the universe has the same materials everywhere, and it builds the stars and planets in the same manner, with of course a few varieties, its plausible to think that the same things can be found in the different galaxies.
wow.. I understood less than 1/2 of that but kinda knew all of it. Never dumb it down; you will teach us forever!!
Underrated channel. In few years, it will reach a million subscribers, and I'll say then that I was there since the beginning.
Glad to receive this comment Ramzi.
I Agree
@@InsaneCuriosity Our ancestors are returning to straighten Earths axis, remove the 666 leadership, Insall Atlantis in preparation for next year when Earth will cycle the Sun with a straight axis. The moon is made cycle the Sun in sync with Earth to provide the seasonal changes a straight Earth does not have. This is the purpose of the Pyramids and the secrets of the Masons and the elite. czcams.com/video/towhbsCA9Ek/video.html
The little great things gravity can do..., marvelous!!
🤯 just wanted to make sure I wasn’t the only person confused after watching
No, it's you!
I know it's kinda randomly asking but does anyone know a good website to watch new movies online?
@Marlon Adam try FlixZone. You can find it on google =)
@Zahir Eduardo Definitely, I've been using FlixZone for since april myself :D
Give us more knowledge!! Thank you. 🙂🙃
When acted on by an external force, what makes the proto cloud develop an axis and rotation? How do you 'push' a cloud into spin? For all the separate particles to rotate cohesively it would require a central source of rotating gravity?
Very well said. Liked and shared.
So, why isn't the plane of our solar system lined up with the plane of our galaxy?
Now I wonder if the "direction" plane of our solar system (and others) are effected by the plane of the milky way.
Good video. It would be helpful if you included a clip of planar rotation forming in a lab like when people throw steel balls etc. on to a sheet to show this tendency to form planar unidirectional motion.
Great job I loved this vid
If there is any way you could leave a brief "bloopers" reel at the end of episodes, that would be fun. Similar to Felix’s CZcams channel "What About It". I’m always looking forward to the bloopers reel at the end. It’s that personal touch.
Thanks for the content. My son and I like watching and learning about our solar system
Lol commentator persuasion cracks me up at the end of the video
Very interesting I enjoyed it 😎
Imagine a rubber band stretched between the Sun, a small planet, a big planet and finally another small planet. There's a force (Centrifugal) to keep everything from becoming a big ball. It's basically horizontal with some planets above and some below if viewed on a piece of paper. The interaction will cause the rubber band to become straight and the planets will over time become a disk.
I understand that the orbits of the planets also change in rational distances from the Sun so much so that they can change positions if they aren't a thin disk. That would allow one to pass by another and affects both their orbits when passing close by. They will probably be more tilted and eclectic. IMHO
It actually makes sense. Thanks for the great explanation. Keep up the good work.
A lot simpler explanation would be: For the same reason that Saturn has rings and not a sphere like formation around it.
Subscribed!
One structure in the universe that I find odd, weird, unique and strange is your brain.
Nice explanation
I think you are explaining the effect rather than the cause, the flat plane is a result of the gravitational force being strongest at the center of a massive object like a star, the momentum is helping to keep the planets from crashing into it...
It seems to me that the eccentric orbit of Pluto would infer that it did not form in our origonal formation of our system.
My thought is that it was a later transient trapped into the gravitational field of this sun.
if the cloud of particles got a push from an outside supernova, angular momentum was not conserved. L(before supersova) and L(after supersova) are different.
The orbit of pluto is tilted to orbital plain because unlike other planets in our solar system it was not formed here it must be an alien planet that ventured into our solar system and caught in it's orbit.....
Rotation in 3D can only happen around an axis, effectively reducing one degree of freedom. What remains is the rotation plane. Easy.
If we lived in 4D, it would be different :)
All the rotating particals have a common center of axis by which they all rotate as the rotating speed increases the particals tend to move away due to the centrifugal force and as they move away their plain of distribution will be perpendicular to the axis of rotation....and the meeting point of both the rotating axis and the plain of distribution will be at the center of the sun...
I'm stuck on wondering why the tilt of the galaxies is not uniform or else regular throughout the universe. Either they should all be in the same plane, or else they should all have some predictable orientation, in relation to a vector pointing right back to the origin of the Big Bang.
Thank you
thanks,very interesting and something i have always wondered about. you mention that other galaxies also tend to share the same layout. so are they also on the same plane as ours? does this mean the most future space travel will be practically 2d?
None of the planets orbit the sun in the same plane. this video is bullshit.
No, they are not all on the same plane. We are basically on the plane of the suns equator. The sun has a magnetic field just like earth and so it has a north pole or south pole in the center is the plane of inertia and that is what orients the flat orbit we are in.
How about the tendency of spiral arm galaxies spin in the same motion as how planets and moons evolve in their spiral rotation around the Sun... Could the way we see galaxies form be a model for begin formation of solar systems?
I still don't get it why almost every planet or sun is moving to the left.
And if it's so if you look it from the other side it moves clockwise....
So how can we say it moves that way... it just from which angle you look at it
My goodness, you are right, weird and shocking. But I guess since the big shots are at top they call it.
Marco Davinci because we say the North Pole is at the top?
I believe that other galaxies do have the power to vary in their structure, because why not? Space has the potential to defy everything we thought we knew, so what makes us really believe that there is one sure structure galaxies should have?
Too many ads. Moving along
The hex shape in saturn's north pole. It'll be interesting to hear an explaination on that one.
What about that big hole called Uranus?
(The above comment expires in 2620 after the renaming of the 7th Planet.)
Gravity verses centrifuge
thanks for explaining this, its logical but i never undertood how the whole universe is flat when you can see stuff in all direction. i would love to see a video about that
video starts at 2 minutes
Great content :) keep it up
If I had a clever brain I could understand all what you say............:))
Jupiter does have moons that orbit in a regular planar orbit, but it also has 63 known moons, a lot of which don't conform to the planar orbit theory you describe here. Video that I found using Google showing it's moons with irregular orbits: czcams.com/video/5l2tR2smeHY/video.html
Also please note that while the Milky Way galaxy that we are a part of may seem relatively flat, it's stellar disk is approximately 170-200 000 light years in diameter and, on average, approximately 1,000 ly (0.3 kpc) thick That's a substantial amount of 3-dimensional space that this galaxy we are a part of is taking up! :D
Please also note that the size and thickness has been taken from the Wikipedia article, slightly modified to suit the syntactical structure of the sentence I was writing, but mostly copied and pasted as for the actual data itself. en.wikipedia.org/wiki/Milky_Way
I would therefore suggest that before you write a dialogue for a video, that you research your facts. You seem to have researched the basic principles but not everything was exactly as you said. Had your margin of error been a lot greater, you might have earned a dislike, as it stands, you earned a like because the content was overall reasonably accurate. You should, however, always want to strive for the highest accuracy possible as accuracy of information presented is important.
❓ Why aren't the BIG 3D structures - The Cosmic Web - in disc shapes, rather than ... Swiss Cheese, with huge voids? ❓ Great show 😏🙃😎👍
Way too less view and way to underrated... This is the best channel I've ever seen about those topics!
I sincerely agree
How about Neblua.....Nebulae?,....Nebulai...Nebulusses lol I like that one.
Why are they odd beautiful shapes?
What about Gyroscopic (rotational) forces. Are they also involved ?
4:20...I briefly woke up
Before watching I’m going to guess time. Objects in the solar system colliding and getting destroyed until all that’s left is what’s there.
0:42 really balls 😉
What do you think it would feel like if the Milky Way galaxy splashed into the black hole in Uranus
Eccentric orbit is not a circle. The Perigee and Apogee aren't equal as seen in the orbit of a comet.
The tilt is the Inclination compared to a reference plane.
Oh, and look at the difference of the ecliptic to the rotational plane of the Sun. How does that happen without a HUGE 3 body solution?
So you’re saying the Earth prefers to be flat as well? Considering angular momentum. 🤔
I've always assumed that the solar system was flat because the planets, asteroids, etc have all settled into the plane of where the sun's gravity exerts the strongest force, even if it's only stronger by a tiny amount. Was this is a complicated way of saying that?
No, it has nothing to do with gravity being different in one direction.
Irony of the universe - earth is not flat but it is... 🤣 (puns intended)
did you ever wondered why? maybe we should asked why there is space ? galaxies,stars,planets floats in the vacuum of space ? if bigbang came from nothing?
wow almost at 69.420k subs keep up the good work!
But why this plane? Because it only makes sense that the sun also has a spinning core just like the other gas giants. The plane is decided by both its rotational gravity, and other gravity factors from outside the solar system.
Also want to point out that I think asteroid belts are formed by breaking of planets on their orbit. Meaning those asteroids use to be a planet, and the belt was its orbit. Same with planets rings having been smaller moons that broke apart. These weren't just stray peices of rocks that happened to magically all gather in a circular orbit. But I'm no scientist
There are so many structures in our known universe that are odd and can’t be described
Also. You can have a triangle with three 90 degrees angles on a sphere, thus our planet is NOT flat but a sphere.. In space if you triangulate 3 stars that are really far far away from each other. You never end up with corners having 90 degree angles. This suggest the nature of our universe is also FLAT like.
the explanation for y the planets r in a plane wasn't sufficiently explained in my opinion
All the rotating particals have a common center of axis by which they all rotate as the rotating speed increases the particals tend to move away due to the centrifugal force and as they move away their plain of distribution will be perpendicular to the axis of rotation....and the meeting point of both the rotating axis and the plain of distribution will be at the center of the sun...
Because they don't orbit the Sun in the same plane. The videos is wrong.
Mystic Gohan stop smoking crack
Why repeatedly show the planets and the Sun upside down (orbiting / turning in the wrong direction)?
Can make a explanatory video for Einstein's train & lightening experiment
What I think is so limited, this universe is one of many reasons I don't understand. All the other universes I even know less about although learning what's out there even if it's not per say truly accurate. It's nice to even wonder if it is. Even if one day we find out there are more unusual and habitual planets out there then we figured to begin with.
Its actually more like a vortex. And it is 3 dimensional. The sun is moving at a fast rate of speed in a particular direction and the planets are being carried along with it. Over the eons everything slowly lined up in the most efficient way possible to trail along while also orbiting. Think of it like a badminton. That little weird looking ball (shuttlecock) with the netting trailing along the direction it flies along. as anything gets trapped in the gravitation pull of the Sun...from whatever direction it comes in from...over millions or billions of years gravity will slow it down here and there to line it up in the proper place its mass, trajectory, and velocity equal out too....because it can't keep jutting our ahead of the sun in the direction the sun is traveling without being slowed down and brought back in somewhat. Comets and the outer Ort cloud of debris are objects that are still in the process of being hemmed in to the proper alignment within the vortex.
What If Pluto's irregular orbit is due to a large body of mass that is at a higher plane than the regular plane the other planets follow? What If the outer planet we are looking for is much higher? Would this not explain why pluto rises when it's further from the sun and dips lower as it approaches the sun?
Could be a video
Unfortunately we have yet to prove how a planet forms. So this is all guess work and has no basses in fact. Particles collide and do not stick to each other because of this it's not possible to make a planet.
Awesome video 👍
Then why are planets round and not like the pizza dough?
mmhh i guess cuz of surface tension
I have seen Vsauce's video the planets are orbiting our sun and the sun is moving through space as well, which makes sense our solar system is moving in the galaxy.
But I do wonder if our solar system is 2d flat orbit system, how our solar system orbits in the galaxy.
They absolutely not orbit in the same plane... There is almost 7° difference from the lowest to the highest inclinations. And 7° is a huge difference, especially in this kind of radiuses.
If it's not a huge difference, then why the parsec is defined as PARallax SECond? You know, an arcsecond is 1/3600th of a degree. One degree could be the difference between life and death even in here on Earth, where the distances are far-far shorter then in space.
The KBOs are part of the system, and a lots of them have high inclination. If you say for example Pluto is in the same orbital plane as Earth, then a plane is nothing else then a sphere.
The invariable plane is just an AVERAGE plane of momentum. Its only a mathematical/geometric function, describing some mechanical observations. It doesn't define a strict orbital plane. All the planets orbit in a different plane.
simply fascinating 👍
Odd structures: Galaxies in ball shape
Thousands upon thousands of weirdly orbiting objects. My guess just like tidal locked objects the gravity is not universally equal and objects line up with the strongest gravitational pull. Won't explain pluto and the rogue objects tho including "planet 9"
What would feel like to be on pre earth? would air be better then it is now? or would you die from to much oxygen? I'm just curious
Pre Earth's atmosphere would have been a thick poisonous cocktail. Free oxygen didn't happen for a long long time, and its advent was the cause for the very first known thus far mass extinction.
Although planets do seem to orbit in the same plane, they follow the sun which follows the motion of it's galaxy's arm. Even though we SEEM to orbit in the same plane - 'flat' we are actually 'following' sun at the same time which not only spins around itself but also has its own movement. Check out this video: czcams.com/video/IJhgZBn-LHg/video.html
great.. now flat earthers are gonna deny existence of 3rd dimension :/
My 1st guess it is because of centrifugal force.
same plane? really? because they don't. that's a very simplify description of the solar system.
He doesn't know what he's talking about.
Like to learn, this was great. Great for getting away from the news.
Contains only 1 min. Of useful information stretched into 15 mins of our lives which we can never bring back :P
Agreed! A lot of unstructured jabbering.
they don't all orbit in the same plane.
Isn't the Milky-way galaxy the accretion disk of the central galactic black hole?
I think the Milky Way formed long before the central black hole. Remember, the galaxy orbits around its center of mass, not the black hole specifically. And considering Sagitarius A still makes up a small fraction of the galaxy's mass, it is likely the center of mass is not even close to SagA.
0:43 I took my picture of Solar System model that I made! :)

Conaervation of angilar momentum
This guy can go back 4.6 billion years to the past and he knows what happened. But, will he remember what food he ate for breakfast 5 days ago?
Why all are in same direction?
This video is a bit miss leading. We are all traveling thru space. So this flat rotation isn’t completely accurate.
I honestly dont understand why you guys dont have a milion views per video.
The Earth is stationary
Gravity disagrees
Does a sun rotate?
The earth's axis isn't upright and is kept stable by the moon
So why am I going to believe that the rest of the our solar system is straight forwards
