NGC 7129 is an open cluster star-forming region located in a reflection nebula that has the shape of a rosebud. The star’s traditional name, Alfirk, derives from the Arabic al-firqah, which means “the flock.” Alfirk serves as the prototype for a class of stars known as the Beta Cephei variable stars. Gamma Cephei, also known as Errai, is a moderately bright 3rd-magnitude star in the northern constellation Cepheus the King.
