It was named after a [[queen]] in [[Greek mythology]] called [[Cassiopeia (mythology)|Cassiopeia]]. It looks like a letter '''W''' or '''M''', with five bright [[star]]s that make the '''W''' or the '''M''' shape. It has two very bright stars called [[Rho Cassiopeiae|ρ Cas]] and [[V509 Cassiopeiae|V509 Cas]]. In 1572, a [[supernova]] called [[Tycho's Star]], or [[SN 1572]], was seen in Cassiopeia by many people. The best time to look for Cassiopeia is in late fall (September and early November.) {{sci-stub}} [[Category:Constellations]] [[Category:Constellations listed by Ptolemy]] {{constellations}}
