The primary component, CS Camelopardalis A, is a blue-white B-type supergiant with a mean apparent magnitude of 4.21m. It is classified as an Alpha Cygni type variable star and its brightness varies from magnitude 4.19m to 4.23m. Its companion, CS Camelopardalis B, is a magnitude 8.7m blue giant star located 2.4 arcseconds from the primary.[17]
