What do the sun and betelgeuse have in common?

Both the Sun and Betelgeuse are stars, which means they are massive celestial bodies composed primarily of hydrogen and helium that produce energy through nuclear fusion. They are both located in the Milky Way galaxy, although Betelgeuse is in the Orion constellation and is significantly larger and more luminous than the Sun. Additionally, both stars are essential for the study of stellar evolution, as they represent different stages in the life cycle of stars.
