The Moon cycles

Phase One:New Moon

Phase three: First Qarter

Phase four: Waxing Gibbous

The new moon is the first phase of the Moon, when it orbits closest to the Sun in the sky as seen from the Earth. The Moon is usually not visible at this time.

Phase Two: Waxing Crescent

The Moon Cycle

Phase Five: Full Moon

Phase Six: Waning Gibbous

"Waxing" means growing and refers to the size of the illuminated part of the moon that is increasing.

A first quarter moon shows half of its lighted hemisphere – half of its day side – to Earth.But we officially call this moon a quarter and not a half because it is one quarter of the way around in its orbit of Earth, as measured from one new moon to the next.

A waxing gibbous moon appears high in the east at sunset. It’s more than half-lighted, but less than full.This moon phase comes between one and two weeks after new moon

At full moon, we are seeing all of the moon’s day side.And that’s what makes a full moon look full. At full moon, the moon and sun are on a line, with Earth in between. It’s as though Earth is the fulcrum of a seesaw, and the moon and sun are sitting on either end of the seesaw.

The moon is past full now. Once again, it appears less than full but more than half lighted.

Phase Seven:Last Quarter

A last quarter moon looks half-illuminated. It rises around midnight, appears at its highest in the sky at dawn, and sets around noon. Last quarter moon comes about three weeks after new moon.

Phase Eight:Waning crescent

A waning crescent moon is sometimes called an old moon. It’s seen in the east before dawn.Now the moon has moved nearly entirely around in its orbit of Earth, as measured from one new moon to the next.
