* Sun: The Sun rotates on its axis, but it's not a solid body like Earth. Its rotation varies depending on latitude. At the equator, the Sun rotates once approximately every 25.05 days. At the poles, the rotation period is much longer.
* Moon: The Moon rotates on its axis once every 27.32 days. This is the same amount of time it takes to orbit the Earth, which is why we always see the same side of the Moon.
* Earth: Earth rotates on its axis once every 23 hours, 56 minutes, and 4 seconds. This is what defines a day.
Important Note: While the Moon's rotation period is close to its orbital period, it's not exactly the same. There's a slight difference called libration, which allows us to see a tiny bit more than 50% of the Moon's surface over time.
