We get day and night because the Earth spins on its axis. Every day it completes one rotation. As the Earth turns, the Sun and stars appear to rise in the East and set in the West.

Learn more about the rotation of the Earth. Use the movies in the table below to view the sky during each season. What you see also depends on where you are in the world!
