Cassiopeia is a constellation in the northern sky, named after the queen Cassiopeia in Greek mythology who boasted about her unrivaled beauty.
Cassiopeia was one of the 48 constellations listed by the 2nd-century Greek astronomer Ptolemy, and it remains one of the 88 modern constellations today.
It is easily recognizable due to its distinctive 'W' shape, formed by five bright stars. It is opposite the Big Dipper.
