The correct order for the life cycle of a SMALL or AVERAGE sized star is: Nebula ==> Protostar ==> Main Sequence Star ==> Red Giant ==> Planetary Nebula ==> White Dwarf.
The phase that our sun, a small to average sized star, will never experience is: Supernova.
5. A group of scientists found a new star in the galaxy. They determined that it was over 5x the size of our sun and is in its main sequence. What would be the next phase of this star’s life?
