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.
What type of star is Thuban?
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.
A first magnitude star is times brighter than a 5th magnitude star?
For apparent magnitudes, a magnitude of zero has the same magnitude as Vega. A first magnitude star is 40 percent as bright and a fifth magnitude star is one percent. So, a first magnitude star is 40 times as bright as a fifth.
What is a second magnitude star?
