Question

Stars rise and set in the sky because

• A. Earth orbits the sun
• B. Earth rotates
• C. The north pole points towards Polaris
• D. The stars are moving in space

Answer 1

Answer: (B)

Earth rotates

The Sun, the Moon, the planets, and the stars all rise in the east and set in the west. And that's because Earth spins -- toward the east.

Earth rotates or spins toward the east, and that's why the Sun, Moon, planets, and stars all rise in the east and make their way westward across the sky.
