As other worte the sun will shine about another 4.5 billions years, but after that it will continue to exists as a dwarf star until it will be merged with another star or a black hole. There is no way to predict when this final death will happen, but it could be alot after the 4.5 bilions years...

The solar isn't alive and can't die. it ought to expire of expendable skill. ~ it is going to run out of hydrogen which will be switched over to helium in about 5 billion years. And sure, it's going to be about ten billion years previous on the prompt. ~ After that it's going to be some better billion years before different fuels are exhausted. ~ it may then take the solar trillions of years to sit back to the position no mild is emitted. this received't ensue because in about 22 billion years from now, in accordance to some theories, the enlargement of the universe ought to tear it aside in an end call the large Rip. Even after the solar stops emitting any mild, it is going to nevertheless exist. If there is no enormous Rip, the subsequent time of existence of our solar is taken under consideration on the order of the time of existence of the proton, popular to be a minimum of 10^32 years. some ordinary grand unified theories anticipate a proton existence of no better than 10^40 9 years. If those theories are not from now on valid, the proton ought to decay by technique of better complicated nuclear tactics, or by technique of quantum gravitational tactics concerning a digital black hollow; in those circumstances, the time of existence is envisioned to be no better than 10^2 hundred years. If protons do decay, the mass of our solar will decrease very slowly with time as its nuclei decay, till it loses adequate mass to change right into a non-degenerate lump of remember, and ultimately disappear thoroughly. .

Our Sun will last for another 4 to 5 billion years. It's half way through it's life now.

The Sun would survive about 10 billion years. There is still 4.5 billion years left.
