Examples of 'main-sequence star' in a sentence
Meaning of "main-sequence star"
main-sequence star - In astronomy, this phrase refers to a star that is currently in the most stable and longest-lasting phase of its life cycle. It is characterized by a state of equilibrium where the star is predominantly fusing hydrogen into helium in its core, producing a steady output of energy. The majority of stars, including our Sun, are main-sequence stars
