Cassiopeia was the wife of King Cepheus. She was very pretty, and would often brag that she and her daughter were more beautiful than the sea nymphs, the Nereids. They complained to Poseidon, who sent a monster to Cepheus' land. In order to save their country, the king and queen sacrificed their daughter, Andromeda. Just before the monster, named Cetus, ate the princess, Perseus saved her. All five figures are represented in the sky as constellations.
Cassiopeia has a very distinct shape. She looks like a "W" or "M" in the sky, depending on where she is. Some legends say that Cassiopeia was chained into the sky and sometimes hangs upside-down to remind others not to be so boastful.
Cassiopeia is a northern circumpolar constellation, so it can be viewed all year long. It is home to several clusters, or groups of stars. M52 is a large cluster on the western edge.
With a telescope, many distant objects can be spotted. There are a few nebulae within Cassiopeia, including the Bubble Nebula and IC 1805. This nebula is located just to the east of the constellation. Finally, a number of galaxies can be spotted, including NGC 185, which is a small distance south of the "W".
