Chronological sequence of stellar evolution
WebStellar evolution begins with the gravitational collapse of a giant molecular cloud. Typical giant molecular clouds are roughly 100 light-years (9.5×10 14 km) across and contain up to 6,000,000 solar masses (1.2×10 37 kg). As it collapses, a giant molecular cloud breaks into smaller and smaller pieces. WebMain-sequence stars derive energy from the fusion of hydrogen into helium in their cores. The Sun remains a main-sequence star today. As the early Solar System continued to evolve, it eventually drifted away from its siblings in the stellar nursery, and continued orbiting the Milky Way's center on its own. The Sun likely drifted from its ...

Stellar evolution is the process by which a star changes over the course of time. Depending on the mass of the star, its lifetime can range from a few million years for the most massive to trillions of years for the least massive, which is considerably longer than the current age of the universe.
