Is Vega the North Star?
Right now, the Earth’s rotation axis happens to be pointing almost exactly at Polaris. But in the year 3000 B.C., the North Star was a star called Thuban (also known as Alpha Draconis), and in about 13,000 years from now the precession of the rotation axis will mean that the bright star Vega will be the North Star.

Is Vega a main sequence star?
Vega is a white main sequence star – A-Class. It is almost twice as hot as the Sun, and its luminosity is about 40 times greater than that of our Sun.
Is Vega a high or low mass star?
Vega is estimated to have a mass of around 2.1 times that of the sun. Vega is estimated to have surface temperatures of around 9,500C (17,000F), which is almost as twice as hot as the sun. Due to its larger size and higher surface temperatures Vega has a luminosity around 40 times greater than that of our sun.
