Quizplus · Accepted Answer

Most local stars in our universe congregate on the main sequence, where they spend the majority of their lives generating energy through fusion reactions. This is because the main sequence stars are relatively low-mass and stable, which allows them to exist for billions of years. The other areas of the Hertzsprung-Russell diagram represent only specific stages or types of stars and are not as populous as the main sequence.
