Rotation

The video explains the concept of rotation in astronomy, focusing on how planets, including Earth, spin on their axes. It details how Earth's rotation causes day and night, and how this movement affects our perception of celestial bodies. The video also covers the difference in rotation times among planets, highlighting Mercury's slow rotation and Jupiter's fast rotation. It concludes with a thought-provoking question about the consequences if Earth stopped rotating.
