What are the main Moon phases?

  • ✅ New Moon: Not visible, dark sky.
  • ✅ Waxing Crescent: Small sliver visible, growing larger.
  • ✅ First Quarter: Half of the Moon visible, growing.
  • ✅ Waxing Gibbous: More than half visible, growing towards full.
  • ✅ Full Moon: Fully illuminated, brightest phase.
  • ✅ Waning Gibbous: More than half visible, shrinking.
  • ✅ Last Quarter: Half of the Moon visible, shrinking.
  • ✅ Waning Crescent: Small sliver visible, shrinking towards new moon.

The Moon's phases are a result of its orbit around Earth and the changing angles at which we see its illuminated surface by the Sun. The entire cycle, from one New Moon to the next, takes approximately 29.5 days, known as a synodic month.
