The Moon reflects sunlight

  • The Moon does not produce light of its own.
  • It shines because it reflects the sunlight that falls on it.
  • The Moon orbits the Earth once about every 27.3 days.
  • The shape we see changes because its position relative to the Earth and the Sun changes, giving different phases:
