read the "life cycle" section

btw, it's going to take longer than 3 billion to 4 billion years.

It may even take up 6 billion years for its hydrogen levels to deplete thus stopping nuclear fusion. (Nuclear fusion is what keeps a star alive)

Hope this helps!

Answer 3

Present state...it is expected to continue for another 3 to 4 billion years more.

Answer 4

About 5 billions. After 5 billions years, the Sun will become a giant red star and then become a Black Dwarf star then it will explodes. Bum !!!

I think human have to say good bye to this solar system before it turns into the Giant Red star.
