Phases of the moon:
- Full moon: The front of the moon is 100% lit up.
- Waxing Gibbous: A small portion of the front of the moon is dark.
- First quarter: Half of the front of the moon is dark.
- Waxing Crescent: A small portion of the moon is lit up.
- New moon: 100% of the moon's face is dark.
- Waning Crescent, Third quarter, and Waning Gibbous are basically Waxing Gibbous, and the other stuff above, but they are reversed. Hopefully, you get what I mean.
Hopefully, this helps! :D
