Guide by the stars

 When you are lost in seas and do not have a compass, look at the sky until you find this shape. AA

This constellation always appears clearly in the clear sky. This constellation looks like a ladle. At the end of this ladle, there is one of the most wonderful stars the name of this star is Polaris. AA

Polaris is located in the constellation of Ursa Minor, the Little Bear. It sometimes also goes by the name "Stella Polaris." The seven stars from which we derive a bear are also known as the Little Dipper. Polaris, the North Star, lies at the end of the handle of the Little Dipper, whose stars are rather faint. Its four faintest stars can be blotted out with very little moonlight or street lighting.AA

 

The easiest way to find it is to use the so-named 'Pointer' stars in the Big Dipper, Dubhe, and Merak. Just draw a line between the two stars and stretch it around five times, then you will finally get Polaris.AA

The reason Polaris is so important is that the axis of Earth is pointed almost directly at it. During the course of the night,The way north is marked by Polaris. As you face Polaris and stretch your arms sideways, your right-hand points due east, and your left-hand points due west. The about-face from Polaris steers you due south. As is widely known, Polaris is not the brightest star in the night sky. It’s only about the 50th brightest. But you can easily find it and every night from the northern hemisphere you will see it shinning in the north sky.AA

Why Does Polaris not Move?

 Polaris is very far from Earth and is located near the north celestial pole of Earth. Earth rotates once a day on its axis, an imaginary line that passes through Earth from its north pole to its south pole. If this theoretical line is extended across the north pole into space, it points at the northern astronomical polar of the earth. As the Earth spins on its axis, it also “spins around” the north celestial pole. Polaris, almost exactly at the north celestial pole, the spine center, is staying in the same spot, while stars farther away from the north celestial pole as seen from Earth during its daily rotation in a wider circle around Polaris.AA

So Within the Northern Hemisphere, you may conveniently locate Polaris every hour of the night, at any time of the year, and it is still to the right north. If you were at the North Pole, the North Star would be directly overhead.AA

In the end when you get lost track of the stars.AA
