The moon cycle

IMG_1365

 

This is what we call the moon cycle.As you can see in this diagram the moon cycle starts at position 1 (New moon) and continues its cycle to position 8 (Waning crescent).There are 8 main phases of the moon: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent.The moon cycle repeats itself every 29.5 days continuing the same pattern.

Because the moon takes almost the same amount of time to complete one revolution as it does one rotation, we see mainly the same side of the moon at all times.During a new moon phase the moon seems to disappear but actually the Sun is shining on the opposite side of it.

As the Sun sets, the Moon rises with the side that faces Earth fully exposed to sunlight (5).The Moon has phases because it orbits Earth, which causes the portion we see illuminated to change. The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days.

The Moon orbits Earth at an average distance of 382,400 kilometers. The lunar month is the 29.53 days it takes to go from one new moon to the next. During the lunar month, the Moon goes through all its phases. Just like the Earth, half of the Moon is lit by the Sun while the other half is in darkness. The phases we see result from the angle the Moon makes with the Sun as viewed from Earth.

In this diagram it clearly shows how the sun has a big impact on the moon phases.Depending on the angle of the moon on earth,Is how we see the moon.

This is a photo of the moon that was taken by  satellite image.The Moon is an astronomical body that orbits planet Earth, being Earth’s only permanent natural satellite.Moon Facts. The Moon (or Luna) is the Earth’s only natural satellite and was formed 4.6 billion years ago around some 30–50 million years after the formation of the solar system. The Moon is in synchronous rotation with Earth meaning the same side is always facing the Earth.

Distance to Earth: 384,400 km
Radius: 1,737 km
Gravity: 1.622 m/s²
Orbital period: 27 days
Polar radius: 1736.0 km (0.273 of Earth’s)
Axial tilt: 1.5424° to ecliptic; 6.687° to orbit plane;
