The life history of a star depends primarily on its mass A little bit on its metallicity ( Z )

Stellar Evolution. Stars form from cool clouds of gas called molecular clouds Gravity overcomes pressure, and several stars begin to form Usually get multiple stars in the same region, about the same age Called clusters Initially, the stars are all moving together at the same speed
