Question

Quizplus · Accepted Answer

The location of a star on the main sequence is determined by its mass, with more massive stars being located at the upper left and less massive stars being located at the lower right. This is because more massive stars have higher internal temperatures and pressures that allow for more efficient fusion reactions, resulting in brighter and hotter stars.
