World View of Day and Night
We experience day and night because the Earth spins around each day. The Earth's rotation makes it look like the Sun and stars move across the sky.

An eclipse is when an object passes through the shadow of another. A solar eclipse occurs when the Earth moves through the shadow cast by the Moon. The sky gets dark, like at night-time!

Earth Rotation

The Earth is always spinning on its axis. It takes 24 hours to spin around once, so it rotates once a day. The Earth spins at over 1,500 km an hour! That's more than 4 times faster than a Formula 1 car racing at top speed!
