Question

Quizplus · Accepted Answer

The majority of stars plotted on a H-R diagram are main sequence stars. This is because main sequence stars are the most common type of star in the universe, and they also spend most of their lives on the main sequence where they burn hydrogen and maintain a stable equilibrium. The other options, red giants, white dwarfs, and Cepheid variables, are all types of stars that are either no longer on the main sequence or have never been on it.
