Cepheus is one of the 48 ancient constellations recorded by Ptolemy, and one of several constellations linked by a single mythology. The King of ancient Ethiopia (which extended over a much larger region than the current country), Cepheus plays a minor role as the spouse of Cassiopeia
, Queen of Ethiopia, who angered the sea-god Poseidon by declaring herself more beautiful than any of the Nereids. (See Andromeda
for the rest of the story.)
Stars that have common names often have multiple names, so the common names shown (if any) cannot be considered authoritative. Right ascension and declination are given in 2000.0 coordinates.
