Quick Summary

Cassiopeia is recognized in both astronomy and Greek mythology.

In astronomy, Cassiopeia is a northern sky constellation easily identified by five bright stars forming a "W" shape. It contains notable celestial objects like Shedar, Tycho's Nova, and the radio source Cassiopeia A.1

In Greek mythology, Cassiopeia was the queen of Ethiopia and wife of King Cepheus. She was known for her vanity, boasting that her daughter Andromeda was more beautiful than the sea nymphs. This angered the gods, leading to a series of events where Andromeda was nearly sacrificed to a sea monster before being rescued by the hero Perseus. Cassiopeia was later transformed into a constellation.123
