Polaris is a Cepheid variable star 430 light years away. It has about five times the Sun's mass and has a diameter more than 40 times greater than the Sun's. Because it's an aged star fusing heavier elements for energy, it's luminosity is very high, some 2,000 times that of the Sun. That is why it shines at 2nd magnitude in our skies even though it's about the same distance from us as the Pleiades. This star is also a triple star, the distant companion being visible in small telescopes and the closer one only detectable with adaptive optics or spectroscopy
