Decoding the Lunar Cycle
The moon seems to change shape. But why does this happen?
What Causes Moon Phases?
The sun, Earth, and moon line up. The moon doesn’t make its own light. This gives us phases.
The Eight Primary Moon Phases
There are eight main moon phases.
- New Moon: The moon looks dark. It’s between Earth and the sun.
- Waxing Crescent: A sliver of light appears. It grows each night.
- First Quarter: Half the moon is lit. It looks like a “D”.
- Waxing Gibbous: More than half is lit. It’s growing towards full.
- Full Moon: The whole moon shines. Earth is between the sun and the moon.
- Waning Gibbous: The light starts to shrink. Less than full.
- Third Quarter: Half the moon is lit again. It looks like a backwards “D.”
- Waning Crescent: Just a sliver remains. It shrinks before the new moon.
Synodic Month vs. Sidereal Month
These are two ways to measure the moon’s orbit. A synodic month is about 29.5 days. A sidereal month is shorter, about 27.3 days. It’s how long it takes the moon to orbit Earth completely, using the stars as a reference point. The difference matters for tracking moon phases accurately!
