www.eyesonthesky.com Just like Halloween where people change costumes, some stars change their appearance as well. In Cepheus, there are several variable stars that do this - but check out the colors of these stars too. Mu Cephei is a deep orange and Beta Cephei is a blue-white while having a contrasting-colored companion nearby. And Delta Cephei is perhaps the best known variable of all, being the prototype of Delta Cepheids, and varying in naked eye ranges.
