How is the pole star located in the sky? Why is it so special?
The earth rotates on its axis from west to east, therefore, the stars appear to move in opposite direction, i.e. east to west. But pole star lies on the axis of rotation of earth, which is fixed. Hence, pole star appears to be fixed in the sky.
Pole star lies in the northern part of the sky and enables us to find the North direction.
