Cepheid Variable Stars are large and luminous yellow stars in space known to sporadically change size and temperature resulting in pulsing variations in brightness and thus, inconsistent levels of luminosity. There are two types of Cepheid Variable Stars; Type 1 Cepheids (or classical) which are high mass stars with smaller pulsating periods and Type 2 Cepheids which are lower mass stars with greater pulsation periods. All Cepheid Variable Stars, named after the first observed star of this type, the Delta Cephei, change brightness in periods ranging from 1 day to 70 days. (Unknown. 2015)
