Pole stars can be located with the help of the two stars at the end of Ursa Major. Imagine a straight line passing through these stars as shown in Fig. 17.2. Extend this imaginary line towards the north direction. (About five times the distance between the two stars). This line will lead to a star which is not too bright. This is the Pole Star.

Question 13. Do all the stars in the sky move? Explain.
Answer.
No, no star moves in the sky. They appear to move from east to west because the Earth rotates from west to east about its axis.
Question 14. Why is the distance between stars expressed in light years? What do you understand by the statement that a star is eight light-years away from the Earth?

The distance between stars is so large that it cannot be expressed in terms of a kilometer. That is why very large distances, are expressed in another unit known as light year. One light-year is the distance traveled by light in one year. If the distance of a star is eight light-years, it means that this distance is the distance traveled by light in eight years.
