Shortest lived stars

Less than 0.1% of the stars in our galaxy are blue supergiants. With masses of around 100 times that of the Sun, they burn through their fuel extremely quickly and can last as little as 10 million years. Their blue colour is a consequence of their very high surface temperatures of around 20,000 – 50,000ºC (36,032-90,032ºF). One of the best known is Rigel in the constellation of Orion. It is the 6th brightest star in the sky despite being around 900 light years away.
