i know im late but

Explanation:

ROTATION. If you watch the night sky for a few hours, you will see that the stars appear to rotate about a fixed point in the sky (which happens to be near the pole star, Polaris). This motion is due to the Earth's rotation. ... The Sun, Moon, and planets appear to move across the sky much like the stars.
