Cassiopeia represents Casio Paya, Queen of Ethiopia. Cassiopeia is one of the 88 modern constellations of the International Astronomical Union and one of the 48 constellations listed by Ptolemy, an ancient Greek astronomer. Cassiopeia is an easily recognizable constellation, which is opposite to the Big Dipper and one of the polar constellations. Its five brightest stars form a very unique W shape or M shape, which is related to the viewing season. Because it is not far from Polaris, this constellation will not stay up all night at high latitudes.
The symbol of Cassiopeia is the Queen Cassiopeia.
