A Cepheid variable is a type of star that pulsates ra­di­al­ly, varying in both diameter and tem­per­a­ture and pro­duc­ing changes in bright­ness with a well-de­fined stable period and am­pli­tude. A strong direct re­la­tion­ship between a Cepheid vari­able's lu­mi­nos­i­ty and pul­sa­tion period es­tab­lished Cepheids as im­por­tant in­di­ca­tors of cosmic bench­marks for scaling galactic and ex­tra­galac­tic dis­tances.
