What to Focus On

  • The Moon is Earth’s natural satellite.
  • The Moon shines by reflecting sunlight.
  • The phases of the Moon are the changing shapes of the bright portion seen from Earth.
  • A waxing Moon is easiest to spot at sunset.
  • A waning Moon is easiest to spot at sunrise.
  • On full Moon day, the Moon is nearly opposite the Sun.
  • The Moon’s true shape does not change.
  • Only the visible bright part changes.
  • The illuminated side faces the Sun.

Common Mistakes to Avoid

The Moon phases are caused by Earth’s shadow falling on the Moon.

The Moon rises exactly when the Sun sets every day.

A crescent Moon can never be seen in the daytime, and a full Moon is the only Moon visible at night.

Memory Tips

Moon phases are caused by the changing view of the illuminated part of the Moon, not by Earth's shadow
