Scientists guess that it will take another like 5 billion years but that's only a hypthesis. It could die out anytime but not anytime soon. They belive the sun is half way thro it's life....It's already been around for about 5 billion years because they belive the earth has been around for 4.6 billion years. Hope that helps!!!!

Approximately 5-6 billion years from now the sun will enter a Red Giant phase, most likely consuming both Mercury and Venus as it gets bigger. There's also a chance that Earth, having already been scorched to resemble something like Mercury, will also be swallowed up.
Following that the Sun will shrink a little and eventually release the layers of gas until only the core is left.
This will happen well after the human race has either moved on or killed eachother off. So no need to worry.
Also that 2012 stuff is superstitious bullcrap, so ignore it.

A star the size of the Sun cannot change significantly in times shorter than a million years. So even if the fusion in the core shut off today by some magical process, there would hardly be any change for hundreds of years. And the fusion is likely to continue for several billion years to come. So, the answer is billions of years in the future.

hydrogen is the most plentiful element in the universe: the sun contains a high proportion of it. deep inside the solar globe, where the temperature rises to 14,000,000 degrees C, and the pressures are immense, the hydrogen nuclei are combining to form nuclei of helium; energy is released in the process, and it is this energy which keeps the sun shining. as it radiates, the sun is losing mass at the rate of 4 million tons a second. the sun is so large and massive it will not change much for several thousands of millions of years, but by stellar standards it is still no more than middle-aged.

In about 5 billion years.
Remember though, the Sun is not "burning" it is radiating energy due to thermonuclear reaction in its core. The Sun converts hydrogen into helium through fusion in what is known as the proton-proton chain.
If it were burning via chemical reaction it would have burned out a long time ago. (in about 10,000 years.)
So, you don't have to worry about the Sun going anywhere in your lifetime.
