A couple of the above are right. The sun is a nuclear fusion reactor. Hydrogen and Helium are fusing at the atomic level. It's basically like trillions of H-bombs going off all the time. There is no solid part of the sun.
There is also nothing "chemical" about the reaction. It is completely nuclear.

Back in the very early solar system, when it was all gas and dust, it started spinning. Just like when you are in a car and it takes a sharp turn, you feel pushed to the outside edge of the turn, the heaviest materials (the rocks) where pushed away from the center of the solar system, leaving only the light gases in the center. It took millions of years, but eventually gravity compressed the gases in the center of the solar system to the point where a fusion reaction began at the center of what became the sun. That is why the sun is hot.

what? the sun is hot because of the Fusion reaction occuring in it where Hydrogen are being fused together to become Helium. The process releases massive amount of energy. The planet is hot because of 1. weird weather pattern and this year was just a hot year or/and 2. global warming is sneaking up on us faster than we expected

The sun is not burning. If it was, it would have run out of fuel several billion years ago. It is actually the hydrogen gas undergoing nuclear fusion and turning into helium. According to E=Mc^2, this releases quite a bit of energy, mush more than a normal chemical reaction such as combustion.

trafficer is right, the sun is just one giant nuclear fusion reactor. This heats up the sun to roughly 15 million Celsius at the center, and about 5500-5800 C at the surface.

here is a link that discuss what the sun is. Spend sometime reading the site. It maybe a little bit over your head on this subject but gives it time. You will understand it as you get to grade school.

The heat and brightness is from the "gasses" on the sun that are chemically burning!
Weiner roast anyone?

the sun is not a planet it is a star. it caught on fire all by itself.

its combustion cycle, the sun has no hard surface, in fact you could theoretically fly through it.
