the magnitude is 3.6.
The surface temperature of the star Thuban is 9800 K. Another name for the Thuban star is Alpha Draconis. It is thought to be located 310 light years from the constellation of Draco.
Thuban is a blue-white star located in the constellation of Draco.
Thuban has a spectral class of A0. Similar to Vega in temperature and spectrum, but more powerful and more massive. Thuban is no longer a main sequence star, it has used up all the hydrogen in its core and is now fusing helium. That makes it a white giant star, being 250 times more powerful than our Sun. It's about 300 light years from us.
The three major stars in the constellation Draco are Thuban, Eltanin, and Etamin. Thuban was once considered the North Star due to its proximity to the celestial pole.
Magnitude refers to the brightness of a star. There are two main types: apparent magnitude, which is how bright a star appears from Earth, and absolute magnitude, which measures a star's intrinsic brightness.
Its absolute magnitude is -1.20.Its magnitude from our point of view is +3.65.

Thuban is a white giant star, which means it emits a white light.
Thuban is in the constellation Draco. Third star from the end of the tail of the dragon. About 5000 years ago it used to be the Polar star due to the slow wobble of the Earth as it rotates on its axis.
Thuban is a star located approximately 303 light years away from Earth in the constellation of Draco.
The brightest is Gamma Draconis or Eltanin or Etanin (magnitude 2.2) The second brightest is Beta Draconis or Rastaban (magnitude 2.8) Traditionally the star designated as Alpha is the brightest in most constellations but not in Draco. Alpha Draconis or Thuban and is magnitude 3.6
