All stars will burn out eventually. Polaris is about 430 LY away from us, and is a multiple star; there are several stars huddled together to form what we observe as one star. One component is a supergiant, and there is one main sequence star, and one dwarf. There are a couple of other small companion stars in the group. So the death of Polaris is likely to be a rather long and drawn out affair. It won't be fading from the sky any time soon.

Yes, the North Star, also known as Polaris, will eventually burn out like all other stars. However, this will not likely happen for millions of years as Polaris is a relatively young star in its lifespan.

No. The fact that Polaris, the "north star", sits almost directly above the North Pole is a happy coincidence. 3000 years ago, it wasn't, and in another 3000 years it won't be.

Because of the precession of the Earth's rotation, the axis of the Earth "wobbles" with a period of about 26,000 years. In 13,000 years from now, the bright star Vega will be pretty close to being the "north star"; not that Vega will move, but the Earth will have wobbled around to it!

No. Polaris is actually three stars, the most massive of which is about 4.5 times the mass of our sun, about half the mass needed to go supernova.

It may well expolde in billions of years time, but by then Polaris, will no longer be the North Star.
