for how many more years will sun shine?

for billions of years yet.  However the earth won't always be here to see it.

In around 4 to 5 Billion years when the Sun is swollen in its death throes before it collapses into star known as a white dwarf . In fact the whole Earth will be vapourised.\n\nIf you mean by your question when will it be destroyed environmentally, then that's upto the caretakers of this planet wether that is humans or some other species.\n\nOtherwise the Earth will always have an atmosphere of one kind or another until the Sun begins to die.\n\nJules

Yes, in a couple of billion years, the Sun will exhaust most of its hydrogen and enter the Red Giant Phase, its radius will be equal to that of the orbit of Mars. \n\nAstronomical calculations are proof.

Our sun will not supernova.  It will, over a very long time, expand into a relatively small red giant, which will have a diameter greater than the Earth's orbit.\n\nLong before that the Earth will have become far too hot to live on, but the process will be very, very slow -- it'll take over a billion years -- not a giant explosion.\n\nSorry to disappoint you.  I know, you sound like you were looking forward to it.  Funny how many people answering this question think otherwise.  I guess that's the irony of the internet for you.\n\nSee the link below for all the details:

Total life span=8billon+yrs.\nIt may last for another 4.5 billion years.....(and counting)

Considering that the vast majority of stars in the universe are small M type stars I would say that the average life span is 1 trillion years (M type stars can live for 3 trillion years)... The sun is a G2 V type star and will not live that long. It has a few billion years left on the main sequence. After that it will begin to expand and turn into a red giant. After another billion years or so its outer layers will just fizzle out into space leaving a white dwarf. So the total life span of the sun is about 10 billion years.

The world will end with the explosion of the Sun, I believe 400 mill. years (approx)?

depends on a number of factors, how hot its burning, ours should be around for a few more billion yrs.

The sun will rise from west.

Quite a bit has, but the sun still shines through more.

There will definitely be another if not many more.  I'm pretty that it will come soon, maybe within a thousand years.\n\nWow, I'm suprised I'm the only one to believe this.  People, just because it is getting warmer doesn't mean it always will.  Global climate is constantly changing.

very long. this is because the sun is a very large star and will take billions or rather trillions of years. when it does burn out however, it will be big enough to swell so big that it will swallow mercury, venus and possibly earth ^^ good luck

if there really deep then a skin graph but if there light then someone once told me that the sun will fix them over time

It will - every sun eventually burns out it is simply a huge star.  It will burn out in like a billion years or something lol.

in about 4 billion years when the sun runs low on hydrogen then it will evolve into the next step of its life cycle. it will become a red giant like the star betelgeuse is already.\nwhen that happens planet earth will be completely destroyed.

Either when Man destroys it himself, or when the Sun gets too hot in millions of years time. We will have moved by the time the sun gets too hot I reckon.

Yes, the sun will burnout. It is using hydrogen as a nuclear fusion fuel and will run out of it in about 5 billion years. At that time, the hydrogen in the Sun's core will be gone, the outer layers will expand and the Sun will become a red giant. It will continue burning hydrogen (and hellium) from these outer layers for about 1 billion years. Then all the fuel will be gone and what has left form the sun will collapse to form a white dwarf. The white dwarf won't have fuel to burn, but it will be initially very hot, so it will emit radiation for many millions of years before it cools down.\n\nI believe by that time life forms on Earth will be advanced enough to survive in one way or another, including the ancestors of humans. In fact, life forms will be affected by the Sun much earlier. In a 100 million years, the Sun will become hot enough to accelerate hydrogen molecules in the Earth's atmosphere enough so that they leave the planet. This would eventually lead to the evaporation of the oceans (affecting marine life) and all other water. However, by that time, human ancestors or other life forms should have the knowledge and ability to prevent this from happening (moving Earth further away from the Sun, building a protective shield, etc.)\n\nThank you!
