Rings vs Moons: The Roche Limit

How tidal forces prevent rings from forming into moons.

This is in my reccomended because of the name used for the final boss theme of Kirby and The Forgotten Land

[@le_chef-Klown]

I was confused about the Roche limit from the same thing you're talking about

[@ReNailLe]

You are very mature and composed to respond all the unimaginative questions. Or maybe they would understand what you tried to tell if the title was 'Roche Limit How It Works' or the kind. I too, wondered why the debris didnt 'fall' to earth, but I know very well this video is not the one to explain that (happened to see the link you shared about Saturn's ring been raining down its planet on the comment section afterwards). This is a 'what if' in purpose to explain the roche limit, not a place to question the source of A B C D E etc, as if they have never seen a what if video. Thanks for the video, I hope people see it in a smarter way!

Came here from anime called 'Your Name. [kimi no na wa]' which has a beautifully made story and includes a Comet falling down on earth. Saw a part where they mentioned about *Roche Limit* and I knew had heard about it somewhere before. Such a brilliant explanation. Hope you make more of these. Earned a sub.

[@sturdyrocks]

[@OsRaunio]

There are small moons inside the Saturn rings, creating gaps, so it's not pure limit of rings/moons.

[@patbracken]

The Roche limit is different depending on the moon's own gravity. A larger moon can get closer before breaking up.

[@AngryMaximus]

Alright, get the boys together, we are pulling the moon inwards to create an earth ring system.

[@dragonmanover9000]

Wouldn't this be bad for the Earth as well since there are several particles which can crash into Earth? The tides would also probably be much higher and cause severe flooding along the equator right?

[@JetixUK]

who else is here after the kurzgesagt video on the moon crashing into earth?🌚

[@Arcadius97]

Another cons of having rings is having the earth surface continuously bombed by ring's debris

[@Surfingonearth]

Awesome explanation! Will fragments of moon cause earth surface to be uninhabitable and destroy life before they form a ring tho 😢

[@Breen.Machine]

How long would it take for the moon to become a ring once inside the roche zone

[@ricerxp]

Why are you not making more videos? I’ve seen most people say you need at least 20-30 before you start getting real traffic. Keep them up!

[@ItsJustAstronomical]

I've been taking a break from KZbin to focus on my academic research. I'm hoping to make some more videos in a few months.

[@barakpinhas2781]

The moon is very important to our survival because it prevents earth from wobbling or from being tidally locked to the Sun.

[@justtzortz2010]

Subscribed baby

[@nebulousJames12345]

We wouldn't be thinking about the rings when our tilt is unstabilised! That'll bring some funnno weather

[@eddiesix27]

Saturn had a pretty big moon inside Roche limit to form those rings. 🤔

[@giselleangela8101]

the best explanation of roche limit I've ever seen

[@hikodzu]

Nice vid

[@shaan702]

This is a great video I would just add one thing. The tide on the far side of the earth not on the side of the moon is not due to the bulge of gravity. The bulge of water on the side opposite of the moon is because of centripetal force. The bulge on the inside is because of gravity but the other is centripetal force.

[@ItsJustAstronomical]

Thanks, but I'm not following the part about the centripetal force. Where does that force come from? I think it's coming from gravity.

[@electricdreamer]

can you tell us why Saturn has that hexagon at its pole?

[@bombud1]

birkland currents

[@AhmMed.]

i can now imagine how strong the tidal forces of the planet J1407B 💀

[@aleksszukovskis2074]

this would actually be better, cause we could mine those rocks.

[@novarexus64]

So how are moons like Pan forming inside Saturns rings?

[@theSUBVERSIVE]

What would happen to tides on Earth if the moon became a ring? Would orbit be on a fixed axis or would there be precession?

[@ItsJustAstronomical]

Interesting question. I think we would stop having a cycle of high and low tides. The moon would be a lot closer so we'd have more tidal forces. They would just be uniform throughout the day.

[@Peyton_Holder]

Oh now that makes it easier to understand spedification (idk how to spell it) with a black hole 😮 You know it’s told by a smart and good teacher if I can understand it😅

[@ItsJustAstronomical]

spaghettification: to turn something into spaghetti

[@SolarisAndCryo]

1:52 looks like haumea

[@grimreefer213]

If the Earth got rings would that cause a problem with observing space? Obviously the rings itself would block the view but would it not also reflect light from the sun and make the outer universe and solar system less visible?

[@ItsJustAstronomical]

Interesting point, I think you're right.

[@t900HAWK]

Have ring or have waves that’s a tough one

[@ezpixelplays]

Wow

[@c03411511]

Why there are moons in between rings in some planet?

[@farkoffcnt]

There are very small moons in Saturn's rings tho, one is located in between 2 of the rings

[@cliniclown8786]

I thought Saturn had gaps in its rings because there is moons inbetween, is this not true?

[@minecchannel2006]

3:24 wow

[@nonamenolastname8600]

Fuck I sposed to got shopping I finedh the whole day by watching your videos

[@fatinfatonah]

But as the ring formed, it will fall onto us right ?

[@beaconblaster33]

well not us, saturn probably?

[@alandsilva7180]

Why ring but not a sphere? What brings the pieces in the same dimension

[@ItsJustAstronomical]

Assuming it started as a single object, the orbit of a single object forms a ring around the planet. So naturally it would continue in that orbit even if tidal forces broke it apart.

[@sagarraturi3069]

What if Saturn's ring are new or parts of broken moon

[@ItsJustAstronomical]

That's could very well be what happened. One of its moons got too close or maybe an asteroid got pulled in. There's good reason to believe that Saturn's rings aren't very old. The ring material is being pulled into Saturn.

[@goblinandslimefromTH.]

So this is what happened in the new kirbys game final boss

But for sich beautiful ring humans have to sacrifice most of humans to tsunami earthquakes and volcanoes until moon disintegrates into ring

[@DeltaHydrixian]

Though if thats how Earth got rings, we wouldn’t be able to see them because Moon fragments would also be raining down But Slowly Saturn will lose its rings, bur right now there are moonlets being formed by the rings, one example is S/2009 S1

[@jimmyshrimbe9361]

What about shepherd moons?

[@ItsJustAstronomical]

That's a good point. I should have explained about them. Large moons are round objects that are held together by gravity. A shepherd moon is relatively tiny. You can think of it as just a very large rock and it is held together not by gravity, but the same way rocks are held together, by chemical forces.

So, Phobos is falling into Mars and he is getting stretched because he is close to Roche limit

[@ItsJustAstronomical]

That's right. Some people think it will break apart in about 70 million years: www.purdue.edu/research/features/stories/does-mars-have-rings-not-right-now-but-maybe-one-day-2/#:~:text=According%20to%20the%20model%2C%20Phobos,in%20roughly%2070%20million%20years.

[@anissans-zo1bc]

it really feels like if there are way too many rings then all the rings would have enough accretion to make a moon that can handle the gravity of saturn

[@HappyBeezerStudios]

On the other hand there are moons in certain gaps in Saturn's rings that keep them in place. So in some way already existing moons prevent the rings from forming more moons.

[@anissans-zo1bc]

this comment is 10 months what the fuck are you doing on a comment from almost a fucking year ago@@HappyBeezerStudios

[@bekiedude]

Sure we get rings, but also gigantic tidal waves and even the most remote village will have fire raining down on it

[@saldownik]

What if Earth is within Moon's Roche's limit?

[@ItsJustAstronomical]

The moon is less massive so its roche limit is smaller. So the moon gets to earth's limit first and would break apart first.

[@CUXOB2]

There is the balance between centrifugal force and gravity to be considered. How can you explain something looking at just the one. The way it's explained here is as if the moons are not orbiting. Stable orbits for all parts of the moon are not possible because they all have the same angular velocity. So different parts of the moon are trying to fly on different (due to the wrong speed, elliptical) orbits which rips the moon apart. In order to come to this conclusion you must derive that the angular velocity for stable orbits is not the same for all radii.

[@minecraft1111crclone]

Lol XD nice rings

[@AdeelDrew]

So you are from year 0.001

[@callmynamesebastian]

I came up with the theroy that the Roche Limit could exist in our lives. In the sense that if a part of you is attracted to something or someone, but you're not totally attracted.... the part of you that is attracted will be pulled more than the other parts of you and so you will be under a tidal force. I guess under the right circumstances you could be ripped apart... the moral of the story being that if you love somthing or someone - make sure you love it wholly from every part of yourself, or else you may well get ripped apart! #physics :) What do you reckon?! Applicable?

[@ItsJustAstronomical]

Hmm, maybe, I don't know. My videos are all about explaining simple things like astrophysics, not horribly complicated things like emotions.

[@callmynamesebastian]

@@ItsJustAstronomical Hahaha fair play!

[@tylermanzi2190]

But wouldn't the ring of the moon fall into earth?

[@tomchan4915]

Saturn’s rings is a moon to close

[@ibrar6121]

But the title question is not answered yet: why rings do not become moon??

[@ItsJustAstronomical]

Because of tidal forces.

[@ibrar6121]

Ok get that!! but is it possible for a ring to move naturally out of Roche limit to form a moon??

[@ItsJustAstronomical]

@@ibrar6121 I don't think so. I can't think of anything that would lift the ring particles out like that.

[@nox9079]

I like the ring because not I, "WE" looked at the moon for too long. I will plan to turn the moon into a beautiful ring in the future, MuaHahaHA.
