Perseus is a constellation in the northern sky named after Perseus, the mitological greek hero.[1] Perseus is located in the northern celestial hemisphere.[2][3] The brightest star in Perseus is Alpha Persei, that has an apparent magnitude (brightness as viewed from Earth) of 1.8.[1] The best-known star in Perseus is Algol, which is known by its variability in brightness, that can be noted by the naked eye.[4] Algol is a star system formed by multiple stars, of which two eclipses each other and creates the brightess variation.[4] The Perseids are a meteor shower located in Perseus, that are proeminent during the months of July and August.[5] Perseus' border constellations are: Aries, Taurus, Auriga, Camelopardalis, Cassiopeia, Andromeda and Triangulum.
