2500 suns Click to see full answer. Also question is, what is the luminosity of Polaris? 2200 times the Sun Likewise, why is the north star so bright? Polaris, the North Star is quite bright in the northern sky for a number of reasons: Polaris sits almost perfectly directly over the Earth’s northern axis, it is only off by 0.75 % so to the naked eye appears stationary in the sky in spite of the Earth’s rotation.
