Stars WS

Reorder the following

• What happens next depends on the mass of the star.

• Heat and pressure build in the core of the protostar until nuclear fusion takes place. star enters main sequence

• Stars start out as diffused clouds of gas and dust drifting through space, called a nebula

• The star begins to run out of fuel and expands into a red giant or red supergiant

• The force of gravity pulls a nebula together forming clumps called protostars.
