* Main Sequence Star: The Sun is currently in its main sequence stage, fusing hydrogen into helium in its core.
* Red Giant: As the Sun runs out of hydrogen fuel, it will expand into a red giant. This phase is marked by increased size and luminosity.
* Planetary Nebula: Eventually, the outer layers of the Sun will be ejected, forming a planetary nebula (which has nothing to do with planets).
* White Dwarf: The remaining core of the Sun will become a white dwarf – a small, dense, and extremely hot object that slowly cools over billions of years.
Important Note: White dwarfs are the final stage for stars like our Sun that have relatively low mass. More massive stars have different final stages, potentially leading to neutron stars or black holes.
