Answer:
The answer is Option 2: Earth rotates on its axis.
Step-by-step explanation:
Polaris is also more commonly know as the North Star is a triple star system and it appears to us here on Earth as the brightest star in the Ursa Minor constellation. Because the North Star is almost directly in line with the rotational axis of the earth, which is the North Pole, the star appears to stand still in the sky while the other stars in the northern hemisphere seem to rotate around Polaris. It has been used by navigators to help guide them to their destinations when there was no other landmarks to gain a sense of cardinal direction.
