random question X]

In about 4 billion years, it will have exhausted its hydrogen fuel and will start to expand into a red giant star.
That phase will last a billion years or so, at which time it will collapse to a white dwarf and start to cool off (that will take many billions of years).

 

[Defying the Odds.]

In a billion years.

 

[MT theKING]

not in our lifetime. 4.5 billion years

 

[Bilal C]

in 5 billion years its gunna expand to a great size until it consumes mercury venus and earth and then shrink onto its self again until its a white dwarf star

 

[Eddie]

~5 billion years from now it will become a red giant, so that will be the end of its "normal" life. but it will exist long after that and then go out as a white dwarf which will linger quite a while longer. so it depends on what you mean my "die"

In about 4.5 billion years it'll turn unto a very hot Red Giant. In about 9 billion years from now it'll likely completely die.
