Alpha Cassiopeiae (α Cas / α Cassiopeiae ) is the second-brightest Star in the Constellation Cassiopeia ( Magnitude 2.25). It also has the traditional name '''Schedar'''. It is an orange Giant ( Spectral Type K0 IIIa), a type of star cooler but much brighter than our Sun . In visible light only, it is well over 500 times brighter than the Sun. According to the '' Hipparcos '' Astrometrical Satellite , distance to the star is about 230 Light Year s (or 70 Parsec s). Schedar has been sometimes classified as a Variable Star , but no variability have been detected since 19th Century . Also, three companions to the star have been listed in the Washington Visual Double Star Catalog , but it seems that all of them are just line-of-sight Optical Components . The name Schedar (or ''Shedar'', ''Shedir'') comes from the Arabic word '''صدر''' ''şadr'', "breast". EXTERNAL LINK
