'''Algol''', also known as '''Beta Persei''', is a triple star system located 92.8 light years away in the constellation of [[Perseus]]. A star system that has been well know throughout [[human history]], it is also the first and most well known eclipsing binary. Normally Algol's apparent magnitude is 2.1, but every 2 days, 20 hours, and 49 minutes, the magnitude drops to 3.4 for some 10 hours. This is due to Algol A (Beta Persei A) being regularly eclipsed from our point of view, by the dimmer Algol B (Beta Persei B).
