Planets form when debris in a protoplanetary disk accumulates and collapses under gravity, with gas giants potentially disrupting the formation of other planets through gravitational interactions; successful planet formation requires sufficient debris accumulation and appropriate orbital distance from the central star.

I built a proto planetary disk!
Added:[music] >> All right, so This is a bunch of rocks here.
>> [music] >> Which actually should form a planet. So here Here we go.
>> [music] >> They will collide right here.
And form [music] a planet.
>> [music] >> They all collide and just sink.
I don't know.
>> [music] >> This is a protosun.
And here's all the rocks that's are supposed to form planets.
But hold up.
It's supposed to be a planetary disk.
But all these rocks [music] seems like they're just doing nothing.
I'm like this one here.
Anyway, let's just just place some >> [music] >> debris.
Which could later form planet.
>> [music] [music] >> All right, there we go.
Here's the planetary disk.
A protoplanetary disk. [music] >> [music] >> Which creates this amazing thing.
And it just disappeared. Wow.
>> [music] >> You know what? I just know better.
Nebulas, let's some nebulous.
>> [music] >> Which can be >> [music] >> designed by Okay.
>> [music] >> 13 14 15 16 >> [music] >> 17 18 19 20 11 21 22 [music] 23 24 25 26 27 28 [music] 29 Most likely 30. [music] Let's check.
All right. So, most of them they form or [music] else they disappear.
All right, there we go. We're forming some gas giants here.
>> [music] >> One of them is going to collide.
>> [music] >> All right. So, this gas giant moves far far [music] away and then comes back again, but moves close to the sun.
And it's got a big storm right there.
Perfect.
All right.
And here's the [music] second.
Here's the second body.
And it has a really cool texture for [music] a gas giant But anyway, let's use some debris >> [music] >> and just form it in one area.
That way.
>> [music] >> From the debris of the nebula.
>> [music] >> There we go.
They should all [music] collapse and form a planet.
But then they just collapse just go to the gas giant. They just slowly [music] come to the gas giant and disappear. They all disappear.
[music] All.
But we formed a few a couple gas giants [music] here.
One that's just slowly being close to the sun.
And one just having having a orb oval-shaped orbit [music] that gets that is close to the sun but gets real close.
Like super duper close. See? Oh.
Like literally.
>> [music] >> And then it And then it just slowly sinks into [music] the star.
It should have been tugged by that gas giant's gravity.
Now planets kick in.
Since the debris was like failed because [music] of that one gas giant.
Yeah.
>> [music] >> Hope hope this doesn't fail again.
But let's add some more.
Yeah, until we get the maximum.
All right. This might be enough.
All right.
Modified.
>> [music] >> This may be a little rock. Oh, here's another one.
>> [music] >> All right, and they all collapsed. Oh.
It feels like we just formed a rock. A little rock.
Right here. This shoot rock.
>> [music] >> Don't worry. We'll just give it some more debris.
>> [music] >> Debris, yeah. Debris debris.
Woah.
>> [music] >> All right.
It was a planet. It shouldn't been that good close.
>> [music] >> I don't know.
Great.
All of them.
They have to like orbit. [music] All the debris is Oh.
It just snatched from the debris.
This is going to be difficult.
This is going to be like pretty difficult.
>> [music] >> Because to make a planet, it shouldn't been like that.
>> [music] >> All right. So, this could be tugged and be formed a moon.
Great. Then it just like [music] glitter forms an eclipse. Oh. It almost did. It almost did.
>> [music] >> But I was too slow. So, yeah.
It's [music] that and that. Yeah.
City C >> [music] >> Shoot.
>> [music] >> It's enough to be formed with siliceous asteroids.
Let's place enough.
>> [music] >> 6 7 8. Okay.
They all formed and they all form and clump together.
Gosh, they're forming so quickly.
Dang.
Why so quickly, bro?
All right, there we go.
>> [music] >> Now, we just got to place some more.
>> [music] >> All right.
Then they collapse with [music] gravity. Okay.
Great. [music] Now, it's just shape shaped like a geoid.
>> [music] >> That's like a toroid.
Oh, yeah.
>> [music] >> But, in order to become a planet, it shouldn't orbit that close to its own home star.
All right.
>> [music] >> All right, it's still orbiting close to its own home star.
And then it goes far out.
>> [music] [music] >> All right.
But, it needs to be a planet.
Oh, shoot.
>> One more city see asteroid.
I didn't mean that.
I'll get missed.
Boom, it count stick right before [music] it just hit the sun. Oh.
Is Is it enough to Oh.
All right, so our planet our lovely planet has just disappeared in [music] a matter of seconds, okay.
Shoot.
It's out of wall debris, then we're going to expand it.
Okay, we just reached the limit.
That was collapsing [music] into bodies.
All right.
Now debris is hitting.
Debris.
All right, now they're all gone.
Just pretend they're like planets and stuff.
Or maybe not. I think I got this.
Which the last debris could exist before it disappears.
Well, >> [music] >> later an asteroid just gets ripped [music] apart by this asteroid, like that big one.
>> [music] [music] >> All right, this is the last debris.
>> [music] >> Or not yet.
>> [music] >> I'm still addicted.
I can't stop placing debris.
>> [music] >> Okay.
All right, one of the last debris >> [music] >> would be this one. All right, this is the last debris. And if it doesn't hit, then it then they won't [music] become plants.
All right, it disappeared.
Which means they'll still become rocks.
Oh shoot.
>> [music] >> All right, [music] so what if I hit this one?
All right. [music] What if I hit this one?
>> [music] >> All right, [music] so it can become an whole planet.
But >> [music] >> but but here's the twist. Here's the plot twist.
Debris [music] cannot make it a planet.
Not even asteroids either.
So yeah.
>> [music] >> Even though it's can be the size of series, [music] it's still going to look like an asteroid.
>> [music] >> Or maybe I'm just wrong. Just correct me.
>> [music] >> All right.
>> [music] >> Let's place it across its [music] line.
Yep, let's place it across its line.
>> [music] [music] >> Or does it seem good? Oh!
We're going to make it orbit.
So, they just go far out.
>> [music] >> Just like that, that, that, and that.
Will it work?
>> [music] [music] >> All right, then it's going to complete Now it's going to go claim all the debris.
Okay, never mind. It's just simply [music] just grab it up.
Small bodies.
>> [music] >> Oop, yeah.
All right.
So, maybe not. All right.
Let's just form City C.
4704 uh This body would stress ME OUT. OH!
OH!
