The sun

The sun
The sun is very hot and if anyone tried to go on it then they would die because the sun is to hot for anyone.

About the sun
The sun is made of a big ball of hydrogen gas. The sun is in the center of our solar system and it produces light and heat for the other planets and for earth. The sun is not a planet it is a star. The sun is the biggest star in our solar system but compared to the other suns our one is a dwarf sun.

What makes the sun very hot?
In the center of the sun there is the sun's core and the core it is the hottest part of the sun not the surface but the core. You might think that the surface is the hottest part but it isn’t.

Why is the sun so big?
The reason why the sun is so big is because the sun has a bigger mass. Mass means that because it is big it has a bigger gravity and because the rocky planets are small than they have a small gravity. The sun rotates but it does not orbit around it just stays there and rotates.

Conclusion
The sun is also called sol and it produces solar energy which makes light and heat. The sun makes solar flares which goes up and than it goes back down because of the gravity.
