Spectra of Science. 2013. What are Stars?. A large celestial body of hot gas that emits light. Greeks grouped stars in patterns called constellations. Use the unit light-year to measure distances between stars. Generally speaking, . there are two main life cycles for stars. . . The factor which determines the life cycle of the star is its mass. . . 1 solar mass = size of our Sun. Any star less than about three solar masses will spend almost all of its existence in what is called the “Main Sequence”. . 158. What does the term ‘classify’ mean to you?.
