Historically, Polaris was used by sailors and navigators to determine their current latitude while crossing oceans. Please place all questions about Polaris, the brightest star in the constellation Ursa Minor, into this category.
543 Questions
Why isn't Polaris always the pole star?
This is because of the precession of the Earth's equinoxes as well as the motion of the stars, themselves. The precession of the equinoxes takes around 25,770 years before returning to the same position.
Where can one purchase a Polaris jacket?
One can purchase a Polaris jacket from Polaris, Chain Reaction, and Modnique. One could also purchase a Polaris jacket from Amazon, eBay, Derailed, and Southern Cycle Supply.

Polaris is the closest of the three stars.
How many years would it take for the Northern Star light to reach Earth?
Polaris (North Star) is about 433 light years from us, so that is how long light will take to reach us.
whatever latitude you are at, that is the angle to polaris.. and the other way around
What is the temperature of Polaris?
Polaris is a multiple star system comprising mainly F class stars. It may well be a open cluster contain a mixture of A and F class stars.
The main star - Polaris A is about 6,000 -> 7,500 kelvin

What surface temperature is polaris?

Why is Polaris called the north star?
Polaris is called the north star because it is directly above Earth's north pole. So, if you find Polaris in the sky, that direction is north. Actually, Polaris is very close, but not exactly in line with the north pole. It is off by about 0.7 degrees.
Why is the north star so much brighter than other stars?
The north star, otherwise know as Polaris, is brighter than many other stars because it is much closer and perhaps larger than many other stars.
What is the unique about the polaris?
Polaris is situated almost along the axis of the earth's rotation, above the North Pole. As a result, to viewers in the Northern hemisphere, it appears to be stationary above the pole and so acts as a direction finder.
Does the pole star change its position?
The pole star is situated in the direction,which is directly above the geographic noth-pole of the earth's axis.Thus,its position relative to the earth does not change its hence it appears stationary
Why north star important to the aborginal people?
If it's important to anybody, that's because it's a relatively bright star that always remains more or less in the same position, as seen by us.
