Chapter 33, Problem 5TE

If you were to travel to the north pole, where in the sky would you find Polaris, the North Star?

Solution

To determine: The location of the Polaris, the North Star when a person travel to the north pole.

Answer:

The location of the Polaris, the North Star when a person travel to the north pole is straight up.

Explanation:

The stars appear to move east to west direction due to the diurnal motion of the stars. The consequence of this motion is that the Earth rotates from west to east in every $24\text{ hours}$ , and the Celestial sphere moves from east to west.

The Polaris is very closely situated at the axis of rotation of the Earth. The Polaris always looks stationary at the night sky as the other Celestial body moves.

Conclusion:

Therefore, the location of the Polaris, the North Star when a person travel to the north pole is straight up.
