🌕 1. What Is the Moon?
The Moon is Earth’s only natural satellite. It is the fifth-largest moon in the Solar System and is about 384,400 kilometers (238,855 miles) away from Earth.
It takes the Moon about 27.3 days to:
-
orbit the Earth once
-
rotate once on its axis
That’s why we always see the same side of the Moon from Earth.
🌗 2. Why Does the Moon Have Phases?
The Moon doesn't create its own light. We see the Moon because it reflects sunlight.
The Moon’s phases are caused by its position relative to the Earth and the Sun.
As the Moon orbits Earth, the amount of the Moon’s surface that is lit by the Sun and visible from Earth changes, creating the phases.
🌘 3. The 8 Main Lunar Phases
| Phase | Description |
|---|---|
| 🌑 New Moon | The Moon is between Earth and Sun; we can't see it |
| 🌒 Waxing Crescent | A small crescent appears on the right side |
| 🌓 First Quarter | Half of the right side is lit |
| 🌔 Waxing Gibbous | More than half is lit; getting fuller |
| 🌕 Full Moon | Entire face of the Moon is lit and fully visible |
| 🌖 Waning Gibbous | Light starts to shrink from the right |
| 🌗 Last Quarter | Left half is lit |
| 🌘 Waning Crescent | Only a thin crescent on the left |
🔄 The cycle repeats every 29.5 days, called a lunar month.
