The​ sun is a G-type main-sequence star and it is located at the center of our solar system. Besides being the source of the energy that keeps the earth alive, the sun encapsulates the life cycle of an average star as it began its life about 4.6 billion years ago from a molecular cloud that was collapsing and will end its life several billion years from now. In the light of this, the paper digs into the birth of the sun, its present constitution and the source of its energy, as well as the stages through which it will pass in dying, stressing its important role as a stellar evolution pattern.
