The Sun will continue as a stable star for at least as long as its supply of hydrogen lasts. (Hydrogen nuclei are fused together to form helium in its core, with energy given off).
This is predicted to be for the next 4-5 billion years. By the end of that time, the Sun will begin to fuse helium, and as a result, expand in diameter to perhaps 300 times its present size.
After it burns out its helium, it will begin to reduce in size, then cool. That process will probably take another 5-8 billion years.
It is probably safe to say that the Sun can support life on Earth fairly well for at least another 3 billion years, possibly more.

Current scientific research suggests that because the Sun is getting hotter, we may not have more than a billion years left as a species
The Death of our Sun * In the next 1.1 billion years, its brightness will increase by 10%. This will super-heat our planet as a result of a severe greenhouse effect. All of the oceans on earth will boil away and all life will be destroyed. * In about 6.5 billion years, our sun will double in brightness and use up all of its supply of hydrogen fuel in its core. This will cause the sun to begin swelling as it uses hydrogen from the layers surrounding the core. * In about 8 billion years the sun will swell to 166 times its present size. This giant star will swallow up Mercury, Venus, and maybe even our Earth. Our sun will then be what scientists call a Red Giant because it will be very large and red in color. * After all hydrogen fuel is used, the sun will begin to use helium as its fuel. This fuel will burn very quickly and only last about 100 million years. * In about 12 billion years, the sun will eject much of its outer layers and become a smoldering, collapsed core that scientists would call a White Dwarf.

Our sun is just your average star. The brighter blue the star, the hotter and faster it burns itself out. The more red the color the cooler and slower it burns through it's fuel. Our suns usable energy life span is 80% over. Check out Astonomy.com for more.
About 10 billion years (and it's about 5 billion years old now).
10 BILLION YEARS.
Our sun is just about in the middle of its lifespan. It will die in roughly 5 billion years.
With a star the size of our sun it takes 10 million years till it is at its middle life period. This period lasts for another 10 billion years. For a star the size of our sun its lifespan is around 10 010 000 000 years Our sun is at its midlife period, and has about 5 billion years to go.
The life expectancy of a star (E) depends on its mass (M), roughly following the model of E = M-2.5. For a star with a mass twice that of our sun (enter 2 in place of `M`), then the lifespan will give 0.177. Our suns lifespan is around 10 billion years, so this would equate to 1.77 billion years.
it is because the area of sun is covered by moon.
10 BILLION YEARS.
About the same as our Sun. About 10 billion years.
Our sun is just about in the middle of its lifespan. It will die in roughly 5 billion years.
Our Sun is an average star and it has an approximate lifespan of 1 second

Because their total lifespan is very short.

Total Eclipse of the Sun was created in 1999.
um... the lifespan of the sun is 12 billion years, we are about half way to the 12 billion mark. (a little less). I think about 4.2 billion years old. The sun will engulf mercury and venus in the last 2 billion years of its life span, then it will either burn out or explode. If it has a higher mass, then it would explode then turn into a black hole! whopee...
One unique characteristic of the sun is that it is 109 times wider than the Earth. It has already reached its mid-point in its lifespan and will burn for 500 billion years more.
The Sun has been living for approximately 4.57 billion years , and is expected to last for roughly 5 billion more, as it's lifespan is about 10 billion years. :D
