Describe the life cycle of our sun
WebA star the size of our Sun requires about 50 million years to mature from the beginning of the collapse to adulthood. Our Sun will stay in this mature phase (on the main sequence as shown in the Hertzsprung-Russell Diagram) for approximately 10 billion years. Stars are fueled by the nuclear fusion of hydrogen to form helium deep in their interiors. WebThe life cycle of a star larger than the Sun starts in the same way as a solar mass star. 1. Nebula. All stars form from a giant cloud of hydrogen gas and dust called a nebula. 2. Protostar. The force of gravity within a nebula pulls the particles closer together until it forms a hot ball of gas, known as a protostar.
