Inside the constellation
Thuban is a blue-white star located in the constellation of Draco.
Thuban is a star located approximately 303 light years away from Earth in the constellation of Draco.
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.
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.
The constellation Draco was named because it looks like a dragon. It is made up of dozens of stars including Thuban which is known as the dragon's tail.
Draco is a constellation located in the northern sky. Thuban, also known as Alpha Draconis, was the brightest star in the constellation and served as the North Star around 2700 BC. Today, it is not considered a major star in terms of brightness.

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 Draco constellation contains 18 stars that have known planets orbiting them. These stars vary in size, age, and distance from Earth. The most prominent star in Draco is Thuban, which was once the North Star due to the Earth's axial precession.
Thuban is a distance of 310 light years or 1,823 trillion miles, or 1,823,000,000,000,000 miles from Earth.
