A Cepheid star is a type of variable star, which means its brightness is not constant. The relationship between the
brightness of a Cepheid star and its period, or length of its pulse is given by M=-278[log P) - 1.35 where M is the
absolute magnitude, or brightness of the star, and Pis the number of days required for the star to complete one cycle
