So if you go a light year out from the Sun, then you will end up in the Oort cloud, the hypothesized Oort cloud.

That's this whole diagram, is just that dot in this.

You'll find millions or trillions or billions of objects which, in what we call the Kuiper Belt or the Oort Cloud these are clouds of small objects which appear as comets when they fall close to the Sun.

In the clouds.

Clouds

There's something called the Kuiper belt, which some people think Pluto's not a planet, that's where Pluto is, it's in the Kuiper belt.

The gravitational pull is still attracting things to it, and this right here, we speculate is the Oort cloud, and this is where the comets originate from.

Look at those clouds.

I know that cloud, it's a cumulonimbus .

Old cumulus frisby they called me.

The Lagoon Nebula?

Cloud and shade

The nebula.

And at the end, you get things like that.

But what a difference.

Do you see that cloud?

Nothing. It's just a wisp of cloud.

dark nebula

It was kind of warm.

The moon rose above the clouds.

Fire!

Send the ships below the cloud cover.

That cloud bodes rain.

And each of them contains hundreds of billions of stars

Mickey

Well, looks like rain.

I was watching the clouds.

Cumulonimbus.

Dark clouds are a sign of rain.

Look at those clouds.

I flew above the clouds.

We saw clouds above the mountain.

The moon came out from behind the clouds.
