The lunar month lasts 29 days as the Moon orbits the Earth. During this period, the shape of the illuminated portion of the Moon changes in a cycle from new moon to full moon and back to new moon again. Several websites provide information and interactive lessons about the different lunar phases that occur each month as the Moon revolves around our planet.
