It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and remains one of the 88 modern constellations today . The north pole of the ecliptic is in Draco . Draco is circumpolar (that is, never setting), and can be seen all year from northern latitudes . </P> <P> Thuban (α Draconis) was the northern pole star from 3942 BC, when it moved farther north than Theta Boötis, until 1793 BC . The Egyptian Pyramids were designed to have one side facing north, with an entrance passage geometrically aligned so that Thuban would be visible at night . Due to the effects of precession, it will again be the pole star around the year AD 21000 . It is a blue - white giant star of magnitude 3.7, 309 light - years from Earth . The traditional name of Alpha Draconis, Thuban, means "head of the serpent". </P>
