  Gamma Dragonis (γ), distant about 100 light years from us, is the brighest star in the constellation Drago (with an intensity roughly 100 times that of our Sun). It is also called Eltanin (whose meaning in Arab is "dragon") and Zenith Star, because of its proximity to the point directly overhead London.
