Delta Cephei (8 Cep, 8 Cephei) je Bayerovo označení pro čtyřhvězdu nacházející se přibližně 887 světelných let daleko v severním cirkumpolárním souhvězdí Cefea. Její vizuální magnituda je o 0,23 nižší v důsledku absorpce záření způsobené plyny a prachem v mezihvězdném prostoru. Je to prototyp proměnných hvězd zvaných podle ní cefeidy, které procházejí…
