Notes:
Thuban was the Pole Star in 2,830 BC (when it was only 10' from the north celestial
pole), the approximate time the pyramids were built in Egypt. Many of the monuments
built by that society are aligned on Thuban, not Polaris. (The Great Pyramid of Khufu,
the largest of the pyramids, has its main descending passage pointing at where Thuban
would have been at its lower culmination.)
It is a spectroscopic binary with a period of 51.420 days.
From James Kaler's Star Notes:
Among the most famed stars of the sky is Polaris, the north star, its prominence the
result of its position close to the north celestial pole, the star showing the way north to
within about half a degree. It was not always so, however. The Earth's rotational axis
undergoes a slow, 26,000 year wobble around the perpendicular to its orbit around the
Sun. As a result, the position of the sky's rotational pole, around which all the stars seem
to go, constantly changes. Around the time of the Greek poet Homer, Kochab in Ursa
Minor was a (rather poor) pole star. Among the best ever, however, was Thuban, which
was almost exactly at the pole in 2700 BC. It remained better than Kochab up to around
1900 BC, and was therefore the pole star during the time of the ancient Egyptian
civilizations.
Even though the star is in the Dragon's tail, its name confusingly derives from an
Arabic phrase meaning "the Serpent's head," having been borrowed from the name for
another star.
Thuban is among a fairly rare class of hot giant stars, its temperature of 9,500 Kelvin
near that of Vega. It is, however, over twice as luminous as Vega (and 265 times more
luminous than the Sun), its fourth magnitude status the result of its rather large distance
of 310 light years. Its relative brightness tells us that the star, unlike Vega, has ceased
hydrogen fusion in its core and has begun to die. Thuban has a faint unseen companion in

abundance anomalies. It is in fact somewhat poor in metals as compared with the Sun.
