It's a big one?

It is the second largest and it's the one with the biggest ring system.

It's the thing that kind of characterizes it.

The planet is a gas giant, so it's made of gases with a small core.

So it's not like the Earth where we have mostly solid gas.

and then a small atmosphere on the outside.

Saturn is gaseous and very, very high-density atmosphere a long way down inside.

How long would that take us?

So is, is the core the hottest part of the sun because that's where it's all bubbling away?

It is, yes.

And it's powered by converting hydrogen, the most common element in the universe, into helium.

So it's a nuclear reaction, but not like the ones we have in our nuclear reactors on the Earth, which break up big elements.

It's making use, building a bigger element from the smallest one, hydrogen.

So it's fusing hydrogen atoms together to make helium, and in that process, it releases a very large amount of energy, and that energy gradually escapes through the sun.

Uh, it takes probably a couple of hundred thousand years to get from the core to the outside, and then a further eight minutes to reach us.

We can't get close enough.
