People Say That The Notrth Star Does Not Move Is That True???

Question

I Have Been Doing Some Research On The North Star(Polaris) And I Have Been Told That It Move But VERY Little...Is This True???I Have Been Told This Many Times. Is It Or Is It Not???
Personally I Believe That It Does move VERY Little...Heres My Source For My Thinking-

To our eyes, Polaris appears to be motionless at the center of the field of circumpolar stars. All the other stars appear to circle about Polaris. As early as 320 B.C. the Greeks had realized that Polaris did not mark the pole exactly. Until then many people had believed that the heavenly pole was absolutely and eternally fixed. Not so. Polaris has long been moving nearer the North Celestial Pole, as it is still doing now. It will be closest to that position around A.D. 2105--27'. Currently it is about 1° from the celestial pole.

Does Anyonw Have Anything Against This Sight That I Should Know About!!
If So Tell Me Thanks!!!!

Answer 1

The North Star Polaris does move.

Earth has a wobble in it's rotation and it takes about 26,000 years to complete one wobble. This is called precession. While Polaris is currently close to the north pole axis, this is not always the case.

Polaris hasn't always been the Pole Star. In fact, it has only been close to the Pole for the last thousand years or so, and over the next thousand years it will gradually move further away.

Celestial Poles follow a broad circle through the sky. For most of the time, there is no Pole Star at all, but occasionally the Pole will pass near a conspicuous star - we are lucky to live in a time when Polaris fulfils this role.

For the ancient Egyptians, the Pole Star was not Polaris, but Thuban in the constellation Draco. Observers in the future will see yet other stars at the Northern Celestial Pole.


5000 years ago the Pole Star was Thuban
3000 years ago the Pole Star was Kochab
Currently the Pole Star is Polaris
In 4000 AD it will be the star Alrai
In 7500 AD it will be the star Alderamin
In 14000 AD it will be the star Vega

In 28,000 AD Polaris will again be the North Star.

Answer 2

You are correct that is does move slightly. It is about 1 degree from the true pole so it does move in a small 1 degree radius circle once a day. And precession is making it move farther away from the pole at a very slow rate. But for the purpose of just knowing where to look in the sky to see it tonight, it can be considered as motionless.

Answer 3

Polaris (sometimes called the North Star) does move, in fact it moves at pretty much the same speed as most of the other stars in our galaxy. When people talk about Polaris standing still, they aren't referring to its actual motion through the galaxy, they're talking about how it does not appear to move very much as seen from the Earth. The stars all appear to move across the sky as the Earth rotates, but since Polaris is very close to the axis of the Earth's rotation, the circle it inscribes is very small and so it doesn't appear to move hardly at all.

Answer 4

Hipparh[150B.H.]found the Earth-s axe precession with the period T=26000years,so,after T the Polaris will be in the same place.

Answer 5

sure. Stars and the platforms that encompass them are caught in an orbit around the galaxy they exist in. for this reason, they pass from orbiting. The gravitational effects of different celebrity platforms, particularly interior of small clusters, can be seen interior the movements of a few stars. further nevertheless, there exist photograph voltaic platforms wherein 2 or greater stars (binary/trinary, and so on.) orbit one yet another or a component interior the area between them.

Answer 6

This site is perfectly accurate and correct.
So whats the problem with their assertion that the North Star appears to move very little or not at all??

Answer 7

Wow. God's angels must have made a mistake then and the pin that held Polaris in place got lost?

Or it's just Earth's precession at work...

Hmm.... tough... not.
