The position of Polaris in the sky has shifted over thousands of years due to the Earth's axial precession, which is a slow change in the orientation of Earth's rotational axis. This natural phenomenon causes the apparent motion of stars in the sky to change over long periods of time. Over millennia, Polaris will no longer remain the North Star as other stars gradually take its place due to this celestial process.

How long does it take light from our nearest star to reach us?
Several thousand years.
Why has the north star changed over thousands of years as compared to how we see it on Earth?
It's not so much the North Star (Polaris) that has changed; stars do change, but usually not very quickly.What has changed is the direction of Earth's axis of rotation in space. It currently points almost exactly towards Polaris, but this will change over time.
Is Venus also called Polaris?
No, Venus is a planet in orbit around the sun as is Earth. Polaris is a star and thousands of light years away.
Distance from polaris to the polaris?
The distance from Polaris (the North Star) to itself is zero, as it is a fixed point in the sky and serves as the pole star around which the northern sky appears to rotate.
What is the absolute magnitude of POLARIS?
The absolute magnitude of Polaris is about -3.64. This value represents the intrinsic brightness of the star if it were observed from a standard distance of 32.6 light-years.
Does the altitude of polaris change?
Yes. Two thousand years ago, the current Polaris was not the North Star. By the end of the 21st Century it will not be above the North Pole.
How long was religion taught in schools?
Several thousand of years.
Is Polaris the north star?
It is currently but 5,000 years ago the North star was Vega. This is because the Earth's axis wobbles (precession) every few thousand years.
Is there old stuff in England?
after several thousand years of history, there is a lot of it
Was the golden temple the first temple built?
No, not by several thousand years.
During what years was the Ford Escort XR3i in production?
The years that the Ford Escort XR3i was in production for several years, and the years it was in production were from two thousand until two thousand six.
How many light years away is Polaris from earth?
The polaris is 430 light years from Earth.
Is Hinduism older than buddhism?
No Buddhism was established about 500 BCE. Hinduism has roots going back several thousand years before that.
What do black holes have to do with the solar system?

The nearest known black hole is at a distance of several thousand light-years.Not much. The nearest known black hole is at a distance of several thousand light-years.
Explain why polaris does not appear to move relative to the northern horizon during the year?
Because the Earth's axis of rotation currently points very near the star Polaris. This is a coincidence of timing; if we were living several thousand years ago, then it would be Vega that appeared to be fixed in the night sky (the Earth actually wobbles very slowly as it spins, taking about 23,000 years to make a complete circle).
How far back does French history go?
Make that several thousand years!
Did Blaise Pascal invent probability?
No, it was known several thousand years before him.
