All stars have a limited amount of fuel or hydrogen, which at one stage will eventually run out. Some stars like our sun will last up to around 10 billion years. Huge transformations take place but again this all depends on how big the star is. Stars that use helium as a fuel and in the process start producing carbon are usually stars that have a mass of one sun. It also begins burning hydrogen in its atmosphere and, in doing so expands up to 100 times its original diameter to become a //**“Red Giant”.**// It is estimated that in around 4 billion years this will happen to our sun engulfing all the inner planets, roasting the earth to a cinder.
