Altair (star)

Compared to SunSurprisingly, Altair exceeds our sun in many various ways. Altair has 1.7x greater mass. Altair has 10.7 times the Sun's visual luminosity and 9.845 the Sun's bolometric luminosity. Also, Alltair radiates much more ultraviolet waves than the sun. Altair even seems to have twice the amount of elements that are heavier than oxygen based on the fact that Altair has an abundant amount of iron. However, the one of the only things that the Sun exceeds Altair in is its lifetime. Due to its huge amount of heat and mass, Altair will exhaust its core hydrogen faster, therefore the sun will last longer than Altair.
