It is almost directly above the North Pole and so was used, for centuries, for navigation.

How to calculate Polaris?
Find your latitude and that is the altitude of Polaris in the sky.
What is the spectral class of polaris?
Polaris is listed as F7 in the Sky Catalogue 2000.0.
Does Polaris seem to change positions throughout the year?
No, Polaris is always in the same spot in the sky.
What can you see in the sky from earth's north pole?
Polaris
Name the star that appear to be almost stationary in the sky?
polaris
Why does the number of circumpolar constellations depend on latitude?
Circumpolar Constellations are those that appear to circle the North Star, Polaris. Polaris' place in the sky changes based on the viewers latitude. The closer you get to the North Pole, the higher in the sky Polaris appears, and therefore the more constellations appear to spin around Polaris.
What constellation you use in finding directions in the sky?
cassiopea, Orion and polaris
Is Polaris the brightest star?
No. The brightest star in the night sky is Sirius.
Why Polaris is considered to be very satisficant star even through its not the brightest star in earth sky?
Polaris is considered to be a very sanctification star is because it is closer to the north celestial pole. This is the brightest star in the earth's sky.
Why do people who live in Australia never see Polaris?
People who live in Australia can indeed see the star Polaris. They just have to visit the northern hemisphere to do it. The earth's axis has a reasonably stable orientation toward north/south; thanks to the stabilizing effect of the moon, it doesn't swing wildly out of place. So people viewing the sky from closer to the north pole can see the northern sky and not the southern sky. People viewing the sky from closer to the south pole can see the southern sky and not the northern. Polaris is very close to the point the north pole actually points to, which is why it is called 'Polaris', the pole star.
When does polaris rise at night When does polaris set?
Because it is in line with Earth's axis of rotation, Polaris never rises or sets. It is always in the same place in the sky from any given location in the northern hemisphere.
What is the earths axis point?
The north end of the earth's axis points toward a point in the sky that's a little less than 1/3 of a degree from Polaris. That's why, as close as we can tell by our eyes, Polaris appears to mark the north pole of the sky, everything else we can see appears to circle Polaris, and we call Polaris the 'North Star'. The south end of the earth's axis points to a spot in the southern sky with no comparably bright star nearby to mark it.
