Why does the sun always burn and not go out?
The sun burns because it has suffcient fuel but eventually it will use up all that fuel and die. But that will be in about 4.5 to 5 billion years
The sun will eventually use up its hydrogen fuel and become what?
When the sun exhausts the hydrogen in its core and become a red giant.
How many years will it take for the sun to burn out?
The sun is about half-way through its life, and will run out of fuel in roughly 5 billion years. Plenty of time left for that tan you're dreaming about.
Can sun fall into the earth?
No, the sun is too bug to fall into the earth. The sun has used up approximately half of its life. In another 4 billion years or so, the sun will expand to become a red giant. When it does, the earth will be swallowed up by the sun.
When do it mean when the moon cover up the sun not that much?
It's called an eclipse.
Where is the fuel gauge located?
The fuel gauge is located in cars. It is used to tell how much fuel is left in the tank. When this gets low the tank will need filling up with more fuel.
What does solar energy not cause to run out?
Solar energy does run out. The Sun is using up its fuel, all the time. At some moment (oh, in the very, very distant future), the Sun will have no more fuel, and it will stop shining. Long before this happens, it will become unstable, and shine much brighter. In other words, it looks as if our descendants will not die from cold, or lack of food (plants need the Sun's energy), but from heat.Solar energy does run out.

Did the sun blow up?
Why not? It blows after few millions after. That called the death of a star .when all the fuel the sun contains is used up by it, the balance between its gravity and the outward radiation prressure is disrupted (gravity will win) then the sun collapses 3o become a red giant. Thats how sun blows off.

What kind of fuel does the sun use and what would happen if it used it up?
The sun is burning gasses just like the stars. And just like any star, when the gas runs out, it will stop burning and disappear.
How is proxima centauri similar and different from the sun?
Proxima Centauri is a "red dwarf" star. Its composition is similar to the Sun, but with less mass and it's much smaller than the Sun. It has lower core and surface temperatures. The Sun will eventually start to use helium as well as hydrogen as its fuel It will become a red giant then a white dwarf. Red dwarfs don't have a high enough core temperature to use helium as as "fuel". Proxima Centauri will not become a red giant. It will go straight to the white dwarf stage, once it has used up its hydrogen "fuel".
What will happen to earth once the sun uses all its fuel up?
we will die
Why do stars which are much massive than the sun live fast and die young?
Gravity contracts them more, making them hotter. As a result, they burn up their fuel faster.
When will the sun finally be extinguised?
Most of the fuel will be used up in about 5 billion years, but the sun will still shine for a couple of billion more years as a white dwarf. See http:/upload.wikimedia.org/wikipedia/commons/e/ea/Sun_Life.png
What is the fate of a star that uses up all its fuel and is bigger than the sun?
Super nova
The sun will eventually use up its hydrogen fuel and become what?
When the sun exhausts the hydrogen in its core and become a red giant.
How much energy is being used by the sun?
The Wikipedia lists the luminosity - basically the power output - as 3.846×10 to the power 26 Watt (which means, that much joules are output every second). Due to conservation of energy, and assuming the Sun works more or less continuously, that's also the power which is used up inside the Sun.
