First, the sun is not a planet, it's a star.
Second, the sun isn't "burning". Burning would involve chemical bonding with oxygen, and the sun doesn't have oxygen. The sun is really a giant nuclear fusion reaction.
Third, falling stars, or shooting stars, aren't really stars at all. They're meteors entering the earth's atmosphere. Meteors are essentially rocks falling from outer space. When they enter the atmosphere, atmospheric friction heats them up until they glow (thanks to their very high velocity).
Lastly, the sun will eventually exhaust its nuclear fuel (hydrogen), but that won't happen until billions of years from now. It won't become a "falling star" though.

1) The Sun is not on fire. It's a superconductive plasma that's powered by fusion in it's core, which releases energy.
2) No. Planets are much smaller than stars and aren't large enough to start fusion in their cores. They don't produce their own light.
3) Stars eventually use up all their fuel (hydrogen) and either explode or gradually die out, depending on how massive they are. They do NOT become falling stars. You don't want a star falling on the Earth - they are many millions of times larger than the Earth. Just look at the Sun. Falling stars are small pieces of rock hitting the atmosphere and creating a visible shock wave as they burn up.
4) Yes, our star will die. In about 5 billion years, it will expand to a red giant, and then shed it's outer layers and spend the rest of eternity as a white dwarf.

OK First the Sun is a Star because it is just a burring ball of gas. This answer the second part of ques ton because all stars are is just gas. Stars burn out because they run out of fuel then they just die, or become a black hole. "Falling Stars" are actually not stars at all they are just space junk like rocks that fall into the Earth's atmosphere and burn up creating the effect that people call "Falling" or "Shooting" stars. Well the sun will eventually burn out but that won't happen for a long time.

The sun isn't a planet. It's the nearest star. Our star.
Fire here on Earth requires oxygen, but the sun'r fire doesn't need it because it is not a chemical reaction like our fires are; but energy released from nuclear fusion reactions at the sun's core.
Stars can die when they use up all of their fuel and collapse and explode, and we call these supernovas. They never become the "falling stars" you see, which are bits of space rock disintegrating in our upper atmosphere.

The sun is a ball of gas which is not burning but has a nuclear reaction going on in its core. Think of it as a controlled nuclear bomb. The stars do not become falling stars. Falling stars or meteors are rocks or dust that get into our atmosphere at such huge speeds that they heat up and give off light.

First off, the sun is a burning star....a planet is much, much smaller than a star.
It is burning because of nuclear fusion inside it's core...it's real hot in there.
The sun is made of gases that accumulated and created gravity.
The stars burn out because they run out of fuel for nuclear fusion. Depending on their size, they can turn into a lot of things, including, white dwarfs, supernovas, neutron stars, and black holes.
The sun is not a big star. It is average. When it dies, it will probably become a white dwarf.
Hope this helps :)

The sun is not a planet it is a star.
It is a ball of burning gas.
Falling stars are not burned out stars.
Falling stars are rocks that burn up as they pass through our atmosphere.
The sun is actually a small star.

A falling star is not a star. It is a meteorite burning up in the atmosphere.

The Sun is not a planet, is a star and eventually it will "die",as all the other stars.

THe sun is a compressed mass of hydrogen being turned into helium. The reaction creates ALOT of energy, hence the light.
