Take an umbrella and open it. Make about 10-15 stars out of white paper. Paste one star at the position of the central rod of the umbrella and others at different places on the cloth near the end of each spoke Fig. Now rotate the umbrella by holding its central rod in your hand. Observe the stars on the umbrella. Is there any star which does not appear to move? Where is this star located?
If there were a star located where the axis of rotation of the Earth meets the sky, could this star also be stationary?
Yes, the star situated at the central rod of the umbrella does not appear to move.
Star located at the axis of the earth meets the sky is also stationary.
Thus, the Pole star situated in the direction of the earth’s axis does not appear to move.
