Study Notes
The Moon
- The moon is a dark (opaque) body that orbits the Earth.
- It is the closest celestial body to the Earth.
- It appears illuminated as it reflects sunlight.
- Its rotation around its own axis also takes 29.5 days.
- Its revolution around the Earth takes 29.5 days.
- The time of a complete rotation orbit of the moon around the earth is the same time of its complete rotation around its axis.
- Observers on Earth always see one side of the moon.
- The moon appears to change shape throughout the Arabic (lunar) month, but it doesn't actually change.
- In fact, what changes is the size of the part of the moon that can be seen from the illuminated part that reflects sunlight.
- The moon orbits the Earth from east to west, so its position relative to both the sun and the Earth changes, leading to eight phases.
Moon Phases
- The phases of the moon are the different stages that the moon goes through during its orbit around the Earth.
- They are a result of the changing of its position relative to both the sun and the Earth.
