What Is The Oort Cloud?

- Looking at where we are now. With our back to the sun, and the Planets, Asteroids and comets behind us, we face Deep Space. There’s nothing between us and the stars that are very far away. Or is there? The Empty space beyond Neptune is not empty. What if we tell you that the Solar system is in the centre of a Giant ice-cloud! This cloud might be filled with billions and trillions of comets and other objects. What is the Oort Cloud?

Before talking about this cloud, let’s talk about what are comets? Comets are cosmic snowballs of frozen gases, rocks and dust, orbiting the sun. They are typically the size of a town.These comets while orbiting the sun, get close to it and in the process are heated. Upon heating, they emit dust and gases into a giant glowing head. The dust and gases form a tail that stretches away from these for millions of miles. There are two main classes of comets : Short-period comets (also called elliptical comets) and long period comets. Short period comets are generally accepted to have emerged from either the Kuiper belt or the Scattered Disc which are two linked flat discs of icy debris beyond Neptune’s orbit at 30 au and jointly extending out beyond 100 au from the Sun. Short period comets have an orbital period of less than 200 years and orbit the Sun in the same plane as the planets. Long period comets have tilted and wildly elliptical orbits and appear from every direction in the sky. Their orbits last for thousands of years. The orbits of comets within the Kuiper belt are relatively stable, and so very few comets are thought to originate there.
But there is a problem here. Comets loose material and burn up when they fly by the sun and melt in the spectacular process which creates those gorgeous tails. After an interval of time comets disappear, and yet new comets keep coming. It's been nearly 4.5 Billion years to our solar systems birth and yet these comets are still appearing from nowhere. So where are they coming from? And what makes them come toward us? This was a very puzzling question back in the mid- 20th century. It was first theorised and solved by Dutch Astronomer, Jan Oort in 1950. He was also the first person to find the evidence for dark matter. He also found the distance of our Solar System from the Centre of our Milky Way. To understand what he proposed, lets go a bit back in time, about 4.5 Billion years back. Lets Observe our solar system, coalescing out of a flat disk of material around the sun, the inner planets were warmer, smaller and rocky while the outer planets were in a region that was freezing and grew huge. As this part of the solar system was chillier, water came in the form of ice mixed with dust and other stuffs. These pieces would then collide and stick together, and in the process they grew bigger. So, after the planets formed, the region in which they were formed still contained lots of these leftover chunks of ice and stuff called Planetesimals. Planetesimals formed the same material as the planets did. But those outer Jovian planets, they had a lot of gravity and any piece of chunk that got too close to them, were either assimilated in them or got thrown into highly eccentric orbits. They were either thrown towards the sun or flung out into Deep Space. Trillions upon trillions of such ice balls got tossed around by the planets. These small chunks with a very little gravity pulled on the heavy planets and the planets did the same. Though, the gravitational pull of these small chunks of ice was not much, but after trillions of these encounters, it accounted. So, the overall effect of all these encounters was that the Saturn, Uranus and Neptune moved outwards and Jupiter moved Inwards. As Neptune was moving outwards, it had a lot of encounters with these ice chunks and flung them into wild elliptical and tilted orbits. This shuffling and moving of the outer planets is what caused the Late Heavy Bombardment in our solar system.Today, there are three distinct populations of these objects. One is a region called the Kuiper belt, named after the Dutch Astronomer Gerard Kuiper. Comets in this belt have a stable orbit aligned with the planets.

Since there is an "Oort Cloud" around our solar system, does it stand to reason that many other star systems will have similar clouds? Small bug in the animation of the Voyager space craft. The main dish was pointed in the direction of movement. It should be pointing mostly backwards.
We’re never getting out of this solar system haha
300 thousand years to pass through it. Now how the hell did you work out we are never leaving the solar system? What we do is freeze ourselves. Then float us out there into the interstellar space. One day we will be awoken by something.
4.6 Billion years and we haven’t even been on any planet besides Earth. Wake up!
Me wake up. You havent even read what I wrote. If you had you would have not written what you just did you turkey.
Han Myohset The earth has been around 4.6 billion years, humans have only been around for a little over 100,000. Nothing you said made sense. You’re an idiot shut up.
I dont understand how can they tell us its too far to get there yet the voyagers got there in only 40 years
I guess my last question was answered I had seen other videos that claimed that Voyager one was already in the Oort cloud, they've also seen other videos claim that Voyager 1 has already left the solar system
Voyager has left the majority influence of it's solar rays to the larger influence of the galactic cosmic rays. Voyager is still under the gravitational influence of the Sun all though weaker.
I was literally hoping you’d upload a video about the Oort Cloud, perfect timing!!
Love your content mate, keep up the amazing work. Spread the knowledge out there!
You have officialy blew my mind. Thank you for doing that
Glad you liked it. Our pleasure!
I really love your videos, since i discovered them i can't stop watching, great graphics and everything is beautifully explained. Your videos have really helped calm my anxiety as well, thank you and keep them coming!
Thank you Shez
This was very intriguing love science! 👍🏻
by all means there can easily be a planet size object extremely far from the sun but if its not large enough it could be moving away from the sun and we might never find it
And if it's on an even more highly inclined orbit compared to the other planets, it would make isolating it's location even more difficult.
one of the most underrated science channels, I wish you all the best, keep doing this type of science videos man !
Still 91.1 k is better then nothing
You should be proud of yourself.More helpful information than you realize.God bless you and this channel.
Oh no, not God, leave him out of here. God is fake news!!!
Most Christians did not read their book, because if they read it they would likely realize it does not make much sense.
@@pavel9652 so youre disbelief gives you permission to mock believers? it seems that common courtesy is not typical of most atheists.
@@omega311888 No, I exercised my freedom of speech. Do you have a problem with it? You all seem to be concerned little too much about criticism. Fact is most of Christians have not read their books. In my country dozen women or so died because doctors in hospitals were afraid to perform a life saving procedure during risky pregnancy because of the very strict law rules applied by religious fanatics and the backslash from the church followers. So little bit of criticism is not the worst thing, but apparently too much already.
@@pavel9652 And have tiu not taken a chance to think thag it's maybe the people’s fault not the religion?
I love you Insane people! Inch by inch, step by step, you are well, so perfect,, at introducing young people to real science as it happens. Not just the shows themselves but the interesting comments and debates
They just ripped off an old video.. here is the original czcams.com/video/ZJscxTyI__s/video.html
Sci-fi stories have mentioned Oort clouds.
The most popular is The Dragon Riders Of PERN.
The cloud in that story doesn't seem to be a sphere surrounding the solar system but only occupying an area at the edge of it. A rogue planet captured by the sun of the system has a highly elliptical orbit that carries it through the cloud and back towards the sun. This rogue planet's gravity pulls chunks of ice behind it and this ice is a life form that falls on the habitable planet every couple hundred of years.
This life form breaks down all biological life and absorbs it.
So of the billions of objects out there in the Oort cloud have frozen life such as the building blocks for life?
Including life forms that could be antilife or maybe bacteria and viruses like what has us penned up. Rather than frozen aliens.
Bet they have good weed to keep your fantasy world alive

The aforementioned Sci-Fi Series was written by award winning author Anne McCaffrey. Read it, it'll do you some good.
I was hoping if i got a comment it would be from someone interested in imparting information. Even though Ms. McCaffrey did research and consulted with knowledgeable sources. It was a novel and well written story and stories have plot devices such as Oort clouds.
Like I stated I was hoping one or more informative comment/s not snarky a comment.
Nice job, i love it

QUESTION: What is the Oort Cloud?
ANSWER: Cloudy with a chance of meatballs
Amazing bro thanks!!!
This is an interesting hypothesis. The explanation that if the solar system is 4.5 Billion years old then we need a cloud where comets can originate from because we still have comets. Logically there are just too many assumptions for me to be comfortable with this hypothesis as part of science.
Fascinating.
Gawddammit. Everyone gets it WRONG. The image of rocks almost bounce off each other is certainly NOT what the Oort Cloud, the Kuiper Belt, or even the Asteroid Belt looks likes. Even at the dense part of the Asteroid Belt, one would be hard pressed and extremely luckily to see even one other asteroid in the sky of other, many a moving dot in the star field. GAWDDAMMIT!
A bit frustrating that apparently, no space probe would be operational if they reach the Oort Cloud! Hopefully, the JW Space Telescope can help combat the annoyance!!
By the launch in 2050 that may happen -
I need help with my new years resolution. I've figured out how to change the stars.
My idea for changing the stars includes Orion and Pleiades (Subaru). I figure it's time to put something up there that's relevant to us, don't you think? Take Orion's belt and Betelgeuse becomes the head with a baseball hat. Below the belt are two legs bending at the knee. The feet aligning perfectly under the bent knees. The 3 stars of Orion's belt align perfectly as the 3 fat belt loops on a baseball uniform. The spear pointing at "Subaru" is the bat being swung and "Pleiades" is the baseball flying away after being hit. Put it all together and you get, "THE ALL-STAR." In my case, I see a left-handed batter and I imagine a "7" on the jersey. Which makes him, "Mickey." (As it should be ;-) But you can put any number you want, making, "THE ALL-STAR," any player you want. It'd be wrong of me to not, at least, try. This is me, trying. Pass it on, please and thank you. Don't worry, where I come from, crazy is a compliment. ;-P
this channel is amazing.
Pretty cool
Good luck, as far as hunting for items that far from the sun! As none of them are generating their own light and the sun's light has faded to a mere hint, you need other devices than the usual optical telescopes. Any ideas?
I’m no expert, but the graphics illustrating the Oort Cloud show a wildly exaggerated density of objects, like it’s a crowded place out there. Good info tho and nicely narrated.
Liked and shared
i would love to know the History of that Epic Spacefight at the Edge of the Solar system. who were the Titans Fighting?????
Wait what
What are you on about yu wrongen
Nice
Yup, you already have a thumbs up! Can I give it again? 😀
Edit: But is the Oort cloud proven? is it a theory or a hypotheses?
When i first heard of Oort Cloud in Halo 4, about the UNSC Infinity shipbuilding, i was curious about what Oort Cloud was, so i came here and see what it is. O3o
Nice animation
Halley's comet mass 2.2 x 10 ^14 kg
Earth's mass 6.0 x 10 ^25 kg
Hydroplate theory is a hypothesis that Earth once had huge chambers of water sandwiched between the Earth's crust and its mantle. I think Hydroplate theory origin of comets is more likely.
The oort cloud is made up of magical dark matter, dark wizard energy, loose unicorn hair, and pixie dust.
My idea so I get to name it! What I mean is, no one has claimed it so I'm officially calling, "Dibs." Voyager 1 is now in the, "Milky Way's interstellar time" or "Mikey's Time."
"V-ger's" message has sped up now that it's outside our Sun's, "Time Bubble," or, "Terran Time." It will be faster, still, when "V-ger" sends a message from beyond the Milky Way's time bubble. Then there's Outside the Local Group time bubble. So on and so on until we get outside any influence and into the, "True Interstellar Time Standard." Or, "T.I..." ;-P
Now that "V-ger" is outside our Sun's reach, in interstellar space, it's now in the Milky Way's faster moving, Interstellar Time or "Mikey's Time." This can be proven by turning off everything except its clock and transmitter. Have "V-ger" read time for as long as possible. They WILL show the flow of time speeds up the further away you get from any celestial bodies. Until you reach the Milky Way's time standard or "Mikey's Time."
•Our sun's time bubble: "Terran Time" we know and have measured. In a lifetime, our head is one second younger than our feet.
•Milky Way's time bubble or "Mikey's Time." The rate/flow of TIME outside any influence but within the Milky Way: We just got there and are still figuring what the difference is. Wild guess I'd say time will increase in speed, now and until V-ger is outside the Ort cloud.
•Local Group's time bubble or the rate/flow of time outside of any influence but within the Local Group: Name still open and unknown. Wild guess .08 P-22% to a couple seconds faster, maybe. Used just for reference.
•Outside any influence in the, "True Interstellar Time Standard." (or T.I...) ;-P This name is NOT up for grabs. The rate/flow of time is fastest here. (Time flows fastest here so it's best to use a motor boat and hold tight. Always applies when you're in T.I....) ;-P
A minute is a minute in all. It's the rate/flow I'm talking about. Heck, rivers of time flowing differently might explain dark energy and dark matter.
The Milky Way's Interstellar Time Standard will be known as, "Mikey's Time."
Pass it on, please and thank you.
We don't know yet what can be there.. I'm not sure if there is the planet 9.. maybe one day we could discover something there..
6:05 what is a "Kuiper betl" ? xD
5:20 Between kuiper & oort cloud is the scatter disk
Oort cloud? Oh my!
I give a BIG THUMBS up to any new visitors that have not already Subscribed! Wow are you Gals and Guys ever in for a treat you will never forget!
I'm not an astrophysicist I doubt our little Sun has that much influence out that far. It must also be affected by a Pluto sized planet. If not we would still be dodging massive asteroids, something is holding them out there.
You're right, you're not an astrophysicist so therefore your argument can be ignored.
@@mlc4495 I can read the articles on the Oort cloud available and the astronomers who have studied the subject. Like I said some astronomers think there probably is an undiscovered Pluto sized object in the Oort Cloud. So why the snark? You could have asked me where I read about it and then go learn something.
solarsystem.nasa.gov/solar-system/oort-cloud/overview/
Wikipedia has a nice article on it too.
@@MountainFisher Oh, Wikipedia. OK. LOL
@@mlc4495 Well I mentioned the Wikipedia article as it won't tax your reading comprehension like the NASA link I left, the one you ignored.
Sun and its gravity is what holds them in place. The objects on the far side of the cloud are on fragile orbits, however, and can be easily disrupted.
I truly love how it's possible that the movie, "Star Trek: The Motion Picture," can actually still happen. Go, V-ger, Go!
p.s. They're close enough to 6. ;-P
this reminds me of what would be in the inside of an atom. once you spin a point it has magnetic and electric properties
i like it
EXCELLENT IF NOT OUTSTANDING INDEED !!!! FROM U.K. (2022).
According to one of the graphics the outer edge of the Ort Cloud is closer to Centauri A Star than the inner Ort edge is to Earth. So would Centauri systems asteroid belts then be overlapping with our Ort Belt? Are our solar systems touching each other, there for we’re actually connected to another solar system in a way??
Not sure what do you mean, as I haven't seen the entire video, but the corresponding Oort clouds are more than likely almost touching themselves and exchanging the material. Oort cloud has likely lost a lot of material in the past of the solar system, either to the other systems passing by as well as the galaxy disk itself.
Hello @777CDH - In case you are talking about the visual at 06.30, yes Centauri looks close to the edge of the cloud but if you look closely, the scale is LOGARITHMIC, meaning from left to right, distance increases 10 times for every unit covered. What looks close on right side is indeed 10 times far away.
I can imagine a far lying object traveling in a figure 8 orbit around the two stars. That would be interesting
380 earth masses!!! Wow
The Orth Cloud Is Just Small there is alot To Explore I Wish i was born when humanity do that

@@nightlightabcdprick
Another question I have is whether where is your one is able to detect anything in the Oort cloud since it is supposed to be inside the Oort cloud.
How do you did not put extra power on the New Horizon probe knowing it was going to be going farther and faster that it wouldn’t last longer than voyager
jonathan lavezzi ?
Because it costs money and does not matter. They still have a little delta-v left, so they might intercept one more object. It would not reach the Oort cloud for hundreds of years anyway.
Planet "X" has been discussed for years with no data to back the theories up. Mainly used as a "if it's there than all these dominoes can fall into place". It ties up lots of things with a pretty bow.
We shouldn't be looking for life around other similar stars. We should be looking for other Oort Clouds that house similar stars. It's apparently real easy to die in space, unless you have structures like Oort Clouds, huge burning plasma walls, asteroid belts, magnetism fields etc to protect you.
How have long period comets been used for inference to calculate the existence of the Oort Cloud? I’m curious to know as something that can’t be directly observed or measured, seems to have a lot of facts for something that is just theorised to exist…rather it exists to assist the proposition of how the age of the universe could be greater than the existence of long period comets (circa 100,000 years).
At 9:18, what are those streaks of light flying past Voyager 1?
What is the “Oort Cloud”? 🤔
They conveniently left out...it’s theoretical.
Very conveniently. Nice artist renderings.

@@rudolphguarnacci197 okay I'm an amateur astronomer with 40 years experience but I'm not going to argue about it because I know what's there they're around every other star what makes the sun special
@@danielwebster5748
I get it, Danny. And that's a good point. I'm just a little tired of hearing theories that PROFESSIONAL astronomers can concoct in the cocoon of academia.
I just read that the oort cloud extends from 2000 au out to 100,000 au. Alfa Centari is about 269,000 au. If alfa centari has an oort cloud the same length does that mean that the clouds might overlap. AND does that mean that there is a Lagrange like point in between SOL and alfa centari where objects might collect like Jupiter's Trojans?
Does anybody reading this understand why we are unable to see anyting in the Oort cloud. I would think the reflections from stars or the sun would allow us to see something in the Oort cloud with our telescopes such as the Hubble and the James Webb
Sir oort cloud is also a part of ring in the milky Way galaxy is that correct??
What would be the average distance between objects in the Ort Cloud?
The same as your brain cells - but more interesting
I would like to know this also! Illustrations always show it as being dense enough to see, but still loosely associated. I think it’s not as dense as the illustrations show (as the Voyager probe passed through it with no difficulty). WAIT! I was listening to this as I was typing, and he said that the objects are “tens of millions of kilometers apart”. (At 6:30). Some of them are a mile in diameter, but with lots of empty space between them)
Depends on their size, see the power law. Bigger objects are less common and distance would be easily in millions of kilometers.
In the video you say comets are typically the size of what?
In my life time most of this has been discovered. I am soon to be a great grandfather. I do wish we would have taken the opportunity to send more robotic probes and manned spacecraft out. As a world united we could have done this but we continually build atomic fusion/fission weapons instead. There are enemies of all mankind we should be more concerned with.

What's the oort ☁..???
dead stones when light hits them it shines
We can take pictures and videos of other galaxies, but how is possible to have that of our own galaxy Milky Way sitting inside within 52000+ light years? Please
We don't have pictures of our own Milky Way galaxy like the way you are thinking. All animations that show the spiral of the Milky Way are just that, CG animations or artistic impressions. BUT that doesn't mean it's totally fake, that we don't know what it's shape really is. All GOOD educational animations of celestial objects of the last 25 years are done with the most loving care using the most up to date, very real information gleaned through the observations from the human spacecraft and ground based observatories and models created by researchers in astronomy and physics. Some animations are sensational crap, but serious scientific establishments do want to get as accurate as possible, their animations making the data and conclusions they learned easier to understand for the rest of us humans on the planet.
Maybe oort clouds are the reasons why we don't see any interstellar species... It will be nearly impossible to manuver around these clouds at high speed avoid getting hit even in si fi ... But if don't speed up it will take 100 of years hmmmmmmm
How is anything supposed to clear it's orbit if it's orbital diameter is 2 light years long?
I thought Voyager 2 was farther and faster than 1?
Or are these icy bodies just scattered throughout interstellar space and our solar system is moving through them
Interesting hypothesis. Do you have a link to your research paper explaining your argument?
No paper just an idea
There is as much empirical evidence for his hypothesis as there is for the existence of the Oort Cloud. Ie. zero.
This sounds weirdly ripped off from Crash Course Astronomy
Finally a video without cringy people doing expressions. 😔
I am a science guy for sure. But when it comes to certain realms of "science" -- including this one -- we are just "making this up as we go". Rather than reasoning from observable data, to making a hypothesis and then testing it, the scientists make up a hypothesis that fits whatever they observe, to explain what they cannot explain. This is OK -- a best attempt to explain the unknown -- but it is not science.
Can we actually get past the oort cloud
Commercials galore
There is no evidence for the Oort Cloud.
The evidence is literally cited in the video. How about YOU offer up evidence disproving the existence of the Oort Cloud.
mlc449 I just watched the video again. There is no evidence for the Oort Cloud. All the videos speaks about is how they hope it’s there.

@@EndOfNumberz The arguments for the existence of the Oort Cloud outweigh and arguments against its existence. Those ranting away here with alternative POV's provide ZERO evidence to back up their retarded claims.

It doesn’t matter how many insults you through at me.. the video doesn’t prove there’s an Oort Cloud. It doesn’t even give the slightest evidence.

There is evidence supporting it.
@@pavel9652 what evidence? Has anyone seen it? Or are you just parroting what you were told?
@@caseyg6225 We know lots of comets with near-parabolic orbits and periods in tens of thousand years and longer. There is more observational evidence from just a few days ago showing 460 new objects that could belong to the inner Oort cloud (distances 29 < d < 2500 AU).
@@pavel9652 "could" notice that word and what about those comets? How do scientists know they weren't interstellar? Seriously you need to stop blindly believing everything you were told and start questioning things.
@@caseyg6225 True, especially when things are told by a random guy on the internet with no credentials I suspect. Don't mistake being sceptical with questioning and denying everything ;) I assume good intentions because I am tired of dealing recently with anti-vaxxers, flat-earthers and climate change deniers. Near-parabolic comets are not interstellar because they do not have escape velocity. Since they have calculated orbital periods it is not difficult to grasp. When error bars are too wide, however, the period is marked as uncertain. Astronomers had no issues spotting high velocities of objects such as Oumuamua or 2I/Borisov. Sure, it is not absolute proof, but I think hundreds of icy objects in the range of expected for Oort cloud "evidence that supports its existence".
Typical electrical device lasts a few years, although assuming you could make a few hundred yes, not likely to send a space ship to ort cloud, which video says would take 30,000 years. It would be floating space junk, unable to send back any data. Of course how would you like to work at NASA 30,000 years from now, and your job was to study data from this old space craft.

why the hell am working ? this is super depressing at the same time exciting.or must be lie lie.ohhhhhhhhhhhhhhhh no
Do not say 150,000,000,000 km, or something like that. No one knows what it is. Use the astronomical unit instead.
the reason we keep getting comets is because were actually in a gas nebula which keep forming theses comet and i have proof of this out of my ass ;)
Oort cloud is complete unproven guesswork. Meteorites keep coming and because planets orbit stars the guy called Oort figured there were a lot of meteorites circling out there. Only in yours and my lives it will never be proven unless they get uber fast vehicles.
