Gamma Draconis

Gamma Draconis (γ Dra / γ Draconis) is a star in the constellation Draco. It also has the traditional name Eltanin, also Etamin.It is an orange giant of spectral type K5, 148 light years away. Despite its Bayer designation of "gamma", it is actually the brightest star in Draco, outshining Rastaban (Beta Draconis) by nearly half a magnitude. In fact, the name Rastaban (also Rasaben) was formerly used for Eltanin, and the two terms share an Arabic root meaning "serpent" or "dragon." Because of its proximity to the point directly overhead London, it has also been called Zenith Star.
