STAR is: A huge object in space made up of gas and giving off light and heat from nuclear reactions; the sun is a star
MAIN SEQUENCE STAR is:
MAIN SEQUENCE STAR is: A "main sequence star" is not really a type of star but a period in a stars life. When a star is in "main sequence" it is converting hydrogen into energy. It is then usually called a dwarf star. This is the longest period in a stars lifetime.
