Describe the life cycle of our sun

WebTo put numbers on this, when the Sun was formed 4.5 billion years ago it was about 30% dimmer than at present. At the end of the next 4.8 billion years, the Sun will be about 67% brighter than it is now. In the 1.6 billion years following that, the Sun's luminosity will rise to a lethal 2.2 L o . (L o = present Sun.) WebThe life cycle of a star begins as a large gas cloud. Also, the temperature inside the cloud is low enough that a molecule can form in it. Besides, some molecules such as hydrogen light up and allow astronomers to see them in space. Moreover, the Orion Cloud Complex of the Orion System can be the nearest examples of the star in this stage of life.
