When we look up at the Sun during different points in the day, it appears to be moving across the sky. The Sun does not move; it is the Earth that is moving. The Earth rotates, or spins, on its axis. The “axis” is an imaginary line from the North Pole to the South Pole of the Earth. As the Earth rotates, the Sun hits different parts of the Earth, giving us day and night. The half of the Earth that is facing the Sun is having day, and the half of the Earth that is not facing the Sun is having night. It takes the Earth 24 hours to make one complete rotation on its axis.
The Sun is actually a star. Like all stars, it is a ball of hot, glowing gas. It is the only star we can see during the day. Even though the other stars are in the sky during the day, we can only see them at night because our Sun is so bright during the day. Our Sun looks larger than the other stars because the Earth is much closer to the Sun than it is to the other stars in the sky.
