Because in the future, due to a wobble in how the earth rotates on its axis, known as precession, what we now see as the north star, which we all Polaris, will no longer appear to be in that position.

Does polaris lie at the north celestial pole?

That's one way to say it. Another way is that the earth's axis points at Polaris. That way, you don't have to deal with the subject of "up" and "down", which doesn't really have any meaning once you leave the earth's surface.


What is the angle of Polaris above the horizon at New Orleans Louisiana?

The angle of Polaris above the horizon is the same as the latitude from which you are trying to measure it. Hollywood Florida has a latitude of ~26 degrees, so Polaris is 26 degrees above the northern horizon.


Would one star be more useful for navigation than any of the others?

The Pole Star or Polaris which is also called the north star, in the constellation of Canis Major is exactly above the Geographic North Pole of Earth. If you spot this star in the heavens, then you can say that you are facing north. However this star can't be seen in the southern hemisphere. So the southern hemisphere can locate south by spotting the southern cross star which is exactly opposite to the polaris. At Daytime one can get the directions by seeing the sun.


Is the North Star located in the Milky Way galaxy?

Oh hello there, happy little artist! The North Star, also known as Polaris, is not actually located in the Milky Way galaxy like all of our other celestial friends. It's actually a special kind of star called a yellow supergiant, and it's part of a smaller galaxy that hangs out with the Milky Way called the Ursa Minor Dwarf Galaxy. Isn't that just fascinating?

What is the movement of polaris with change of latitude?

Polaris' 'elevation' ... the angle between it and your northern horizon ... is roughly equal to your north latitude. When you are . . . . . . on the equator (zero latitude), Polaris is on your horizon; . . . in Salem Oregon, Minneapolis, Grenoble France, Torino Italy, Ploiesti Romania, Jixi China, Wakkania Japan, etc. (45 degrees north latitude), Polaris is 45 degrees above your northern horizon; . . . at the north pole (90 degrees north latitude), Polaris is directly overhead; . . . south of the equator, Polaris is due north of you but below the horizon.


What does the Ursa Minor constellation look like?

It looks like an old fashioned plough with a bent handle. Some people say it looks like a pan with a bent handle. To the naked eye, there are seven stars; four of them form the trapezium-shaped plough blade, and one star in the corner joins three others to form the bent handle, which curves smoothly in a clockwise direction, ending with Polaris, the pole star, which is the brightest star in the constellation.


How far is the North Star from the Sun?

There's no precise answer to the question of "Where does space start?"But you might consider it to be the distance far enough off the surface of the earth where artificial satellites can survive in orbit ... meaning the altitude where the atmosphere has thinned out sufficiently so that atmospheric drag is essentially negligible. This places us in the neighborhood of the orbital altitude of the International Space Station, which is a significant milestone; so in order to be able to offer a figure for negotiation, let's say ...Space begins at roughly 220 kilometers (140 miles) from the earth's surface.


What star does not shine?

Yes. Stars are enormous balls of hydrogen and helium that carry out nuclear fusion in their cores. They are extremely hot and so shine brightly. They appear as tiny points of light only because they are so distant.
