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.
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.
