Difference between Supernova and Variable star

Supernova vs. Variable star

A supernova (plural: supernovae or supernovas, abbreviations: SN and SNe) is a transient astronomical event that occurs during the last stellar evolutionary stages of a star's life, either a massive star or a white dwarf, whose destruction is marked by one final, titanic explosion. A variable star is a star whose brightness as seen from Earth (its apparent magnitude) fluctuates.
