What is the evolution sequence for the sun?

The Sun's evolution sequence begins as a molecular cloud of gas and dust, which collapses under gravity to form a protostar. As it accumulates mass, nuclear fusion ignites in its core, marking its transition to the main sequence phase where it spends about 10 billion years fusing hydrogen into helium. Eventually, the Sun will exhaust its hydrogen fuel, expand into a red giant, and shed its outer layers, creating a planetary nebula. The remaining core will cool and shrink into a white dwarf, ultimately fading over billions of years.
