It depends on the star. A moderate, yellow type G star like the sun will run out of fuel after 10 billion years. We are halfway to that point now. In another 5 billion years or so, our sun will begin to run out of fuel and so it will begin to contract in on itself, causing the remaining hydrogen in the core to fuse rapidly into helium. This will generate more heat and will drive the outer atmosphere of the sun outward, where it will form a red giant star and engulf all of the terrestrial planets out to Mars.
When the core becomes unstable, it will puff out this outer atmosphere in a planetary nebula, leaving behind a white dwarf core. This white dwarf star will continue to burn hot and white until there is less hydrogen to burn, in which case it will gradually pass through all of the other colors of the visible spectrum until, after billions of years, it will no longer shine. Then it will be a black dwarf (NOT a black hole!), meaning it will have all of its gravity but will emit no light or other radiation.
Stars with several times more mass than our sun will not last 10 billion years. They burn hot and fast and will go supernova long before that. After this huge explosion, the core will be left behind as either a neutron star or a black hole depending on the mass of the core.
Red dwarf stars last far longer than 10 billion years. They burn cool and red for much longer, and eventually they too run out of fuel and will become a small white dwarf that will fade relatively quickly because of the small mass and far less fuel available.

How can the sun keep burning for so many years without burning out?
It really is burning out, but there is so much gas in it that it will really burn out after about ten billion years.
As a star ages what happens to its composition?
A star's internal composition does not change as the star ages, as a result of rising temperatures. The life span of a star is from one to ten-billion years. Larger, more massive stars have a shorter lifespan than smaller ones, due to the pressure on the core causing the larger stars to burn hydrogen more quickly.
Is the earth 4.5 American billion years old or 4.5 English billion years old?
Though it pains me to admit it, the American definition of a billion - ie; one thousand million or 1,000,000,000 - is considered to be the 'correct' definition, as the British definition - ie; one million million or 1,000,000,000,000 - is not in line with our ten-based counting system.As such, scientists tend to favour the American definition, and it can be assumed that whenever you read the word billion in a scientific or technical text, it refers to that one.

How long does it take for a star like the Sun to evolve from the main sequence to the top of the red giant branch?
A star like the sun is a slow evolving star. It is estimated that it will take about ten million years for it to evolve from the main sequence to the top of the giant red branch.
How long does an average star spend as a hydrogen- burning main sequence star?
Ten billion years

How did the moon ever get to the universe?
A Mars sized body struck a glancing blow to the nascent earth a little more than 4.5 billion years ago. The resulting debris cast off orbited the earth, coalescing into the moon in as little as ten thousand years. The matter for both earth and moon were forged in the heart of a giant star, perhaps six to eight billion years ago. That star was itself a second or third generation star from the origin of the universe, 13.7 billion years ago. We know our universe is 13.7 billion years old from careful analysis of the data provided by the COBE & WMAP satellites.
Did the first cells appear ten billion years ago?
No. Earth itself is "only" about 4.6 billion years old. The first life may have emerged about 4 billion years ago.
How old is the star Betelgeuse?
About ten million years. Betelgeuse is a high-mass star and is therefore near the end of its "life" even though it formed much more recently than the Sun (which is between 4 and 5 billion years old, and still "middle-aged").
How many years tell sun explodes?
A star the size of our Sol may expect to enjoy an existence that spans roughly ten billion years. Sol and our solar system is just over 4.6 billion years young. This leaves 5.4 billion years before Sol 'goes' Red Giant and consumes most likely all of It's planets.
