CAPH (Beta Cassiopeiae). At mid second magnitude (2.27) and just barely the second brightest star in Cassiopeia, almost but not quite as bright as Shedar (the Alpha star), Caph, the Beta star, stole its name from the whole "W" of the constellation.
Caph is a yellowish F2III-IV giant to subgiant star. The luminosity is 130 times that of the sun. The spectrum indicates that Caph is a binary star with an orbital period of 27 days, but there is little information available on the companion.
When Caph is straight up towards the zenith from Polaris, it is celestial midnight, and this star is a 24-hour clock hand moving counter-clockwise around Polaris.
