Question

Quizplus · Accepted Answer

The length of a star's life is determined by how long it can fuse hydrogen into helium in its core, and this is primarily determined by its mass. Smaller stars like the 1-solar-mass star will have a longer lifespan because they burn their hydrogen fuel more slowly and efficiently than larger stars. The larger the star, the faster it burns through its fuel and the shorter its lifespan.
