Stars spend most of their life span as main-sequence stars.

Question

Quizplus · Accepted Answer

Most stars spend the majority of their life span as main-sequence stars, which is a phase of nuclear fusion that occurs when hydrogen atoms fuse together to form helium. This phase can last for billions of years, depending on the mass of the star. After the main-sequence phase, stars may go through different phases depending on their mass, such as red giant, white dwarf, or supernova.
