The Sun is approximately 4.57 billion years old.

It started out as a protostar. Over time, it became what it is today a main sequence star, with hydrogen fusion reactions.

The Sun will stay in its current state for about another 4-5 billion years before it enters its red giant phase. It will then turn into a white dwarf and slowly cool over billions of years.
