Explanation

The Sun is approximately 4.57 billion years old, based on helioseismology and models of stellar evolution. This age is consistent with the oldest meteorites (4.56-4.57 billion years) that date to the Solar System's formation. The Sun will continue fusing hydrogen for about another 5 billion years before becoming a red giant.
