Queen
Cassiopeia was the mythological mother of Princess Andromeda by King
Cephus. After Cassiopeia boasted of the beauty of her daughter,
Poseidon, King of the Sea, demanded that Andromeda be given to the great
whale Cetus as a sacrifice, but she was rescued by the hero Perseus.
Ultimately, the gods placed them all in the heavens as constellations.
Cassiopeia is one of the easiest constellations to identify. The asterism takes the shape of an elongated W, and when seasonally tilted could arguably be said to be a stick figure of a queen upon a throne.
The chief star of Cassiopeia is Schedar; the name means "breast" in anglicized Arabic, and refers to the fact that Schedar indicates the heart region of Cassiopeia. Schedar is a second magnitude star. Schedar can be seen year round from the North Pole as far south as Perth Australia, though the best season for viewing Schedar is late autumn in the Northern Hemisphere. It is the third star listed in the Nautical Almanac.
Schedar is a young star (about 200 million years old) and spent most of its life as a superhot blue star. Having burned off much of its fuel, Schedar is now orange and has expanded to many times its original diameter. It is now 42 times the width of our Sun but only four times its mass. At 7700 degrees F. It is cooler than our Sun, which burns at 10,000 degrees. Schedar is about 230 light years from Earth.
