Quizplus · Accepted Answer

Gravity is the dominant factor in the life of a star. It causes the gas and dust in a cloud to collapse and form a protostar, and it also determines the star's size, temperature, and longevity. The gravitational force is what keeps the star's core hot and dense enough for nuclear fusion to occur, which provides the energy that powers the star.
