#Write2Earn The history of Sol, our Sun, began around 4.6 billion years ago from a collapsing cloud of gas and dust in the Milky Way. Gravity compressed the material, igniting nuclear fusion and forming a protostar that became the Sun. Over billions of years, the Sun stabilized into a main-sequence star, providing energy for life on Earth. It has shaped the solar system, driving climate and evolution. In about 5 billion years, Sol will expand into a red giant, shedding its outer layers and ending as a white dwarf. Its life cycle illustrates the typical evolution of a medium-sized star.
