About Cujam
Cujam, Omega Herculis, is a class B star hotter than the Sun and many times more luminous, though not much larger. To the eye it is faint, a star that needs a dark sky to pick out.
The name comes from the Latin for a club, the weapon Hercules brandishes in the old pictures of the figure. It sits near the border of Hercules with Ophiuchus and Serpens.
