About CassiopeiaCassiopeia, the Queen, is visible in the Northern Hemisphere all year long. She is known as the Celestial W when below the pole and the Celestial M when above it. The wife of Cepheus and the mother of Andromeda, Cassiopeia is bound to her chair and forever circles the pole with her head downward. This was an appropriate punishment by the Nereids (Sea Nymphs) for Cassiopeia's boast of being more beautiful than all of the Nereids.
