Here's the breakdown:
The Sun:
* Apparent Motion: From our perspective on Earth, the Sun appears to move across the sky from east to west. This is because the Earth is rotating on its axis.
* Actual Motion: The Sun is actually stationary (relatively speaking) at the center of our solar system. It's the Earth that orbits the Sun.
The Moon:
* Apparent Motion: Like the Sun, the Moon appears to move across the sky from east to west. This is due to the Earth's rotation, but also the Moon's own orbit around the Earth.
* Actual Motion: The Moon orbits the Earth, moving in an elliptical path. It takes about 27.3 days to complete one orbit.
In short:
* Both the Sun and Moon *appear* to move across the sky from our viewpoint on Earth.
* The Sun is actually stationary at the center of our solar system, while the Moon orbits the Earth.
Let me know if you have any other questions about the Sun or Moon!
