The Sun is approximately 4.6 billion years old. This age is estimated based on the ages of the oldest meteorites found in the solar system and the study of solar models. The Sun formed from the gravitational collapse of a region within a large molecular cloud, leading to the formation of the solar system. It is currently in the middle of its main sequence phase, where it fuses hydrogen into helium in its core. The Sun is expected to continue this process for another 5 billion years before evolving into a red giant and eventually ending its life cycle as a white dwarf.
