Perseus

Constellations of Beaufort County

PerseusOne of the brightest and most interesting stars in Perseus is Algol. The name Algol means "demon star." Ancient skywatchers thought it was cursed because its brightness changes. That's because Algol - which is about 75 light-years from Earth - is the most famous "eclipsing binary" star. Today, astronomers know that Algol is two separate stars. About once every three days, the fainter member of the pair passes in front of the brighter one, and Algol grows fainter.

A faint star cluster in Perseus, called M34 is visible with binoculars.
