Which constellation's brightest star is Alpha Cassiopeia?

Alpha Cassiopeiae, also known as "Schedar," is indeed the brightest star in the constellation Cassiopeia. This constellation is easily recognizable because of its distinctive W shape formed by five main stars. Cassiopeia is named after a queen in Greek mythology who was known for her beauty and vanity. The brightness of Alpha Cassiopeiae makes it a prominent feature within this constellation, contributing to its visibility in the night sky.

This understanding helps clarify the significance of the other constellations mentioned. Dorado, Carina, and Lyra each have their own brightest stars; for instance, the brightest star in Lyra is Vega. However, neither Dorado nor Carina relates to Cassiopeia, making them irrelevant for this particular question. Recognizing Alpha Cassiopeia as the brightest in Cassiopeia demonstrates the importance of associating stars with their specific constellations in astronomical studies.
