Question
how many years does the sun takes to run out or burst out.

Answer
Dear Adeoluwa Agunlejika,

The sun has an expected lifetime of 10 billion years.  That's 10,000,000,000 years.  Right now, it is approximately 5 billion years old.  So, it has about 5 billion more years left before it becomes a red giant.

Expertise

I am not a professional astronomer by any means, but astronomy has been an interest of mine since childhood, and I am well-informed on the subject. If unable to answer someone`s question personally, I will know how to quickly find the answer online, because I keep myself informed about developments in the field and I know where to look for information.

Experience

I worked in an observatory for awhile at one point, doing various interesting things with a computer.
