Location of Thuban

Though it is a faint star in a sparse region of the sky, Thuban is not difficult to locate. It lies halfway between the 'bowl' of the Little Dipper, and the 'handle' of the Big Dipper.

Though only of magnitude 3.7, and by no means the brightest star in its constellation, Thuban is nonetheless designated Alpha Draconis.
