Which of the following is true regarding the Pole Star's visibility?

The statement that the Pole Star, or Polaris, is often used by navigators in the Northern Hemisphere is correct. Polaris is located nearly directly above the North Pole, making it a reliable point of reference for navigation. Its position in the sky does not change much over time, which helps navigators determine true north. As a result, those in the Northern Hemisphere can find Polaris and use it to orient themselves, especially at sea or in unfamiliar terrain.

This star is not visible in the Southern Hemisphere, as it is located in the northern celestial hemisphere. The idea that it helps find south is misleading because Polaris signifies north. Although it appears to have a fixed position relative to the Earth's rotational axis, it does have a slight movement due to precession, thus the statement that it never moves in the sky is not entirely accurate.
