The prefix “proto” means . first. or . original. A . 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?.

Baby star. Composed of gas and dust. Protostar. Center of nebula begins to shrink as it gets hotter . Nuclear fusion begins . Main Sequence. “Middle Age”. Star will spend most of its life in this stage. Stars form in a cloud of dust and gas in space called a nebula.. How do stars form?. A force from outside the nebula causes the cloud to condense into stars. . Example: a shockwave. Gravity causes the particle in the cloud to contract..
