The main phases of the month - new moon, first quarter, full moon, last quarter and next new moon - have an interval of 7.4 days. If you need help in tracking these phases yourself (or if you want to look up the position of the moon on a historically important day), NASA will use dates for all phases of the month during the 6,000 year period And provide an online calendar of the time. From 2000 BC to 4000 AD. NASA 's Night Sky Network is an alliance of amateur astronomical clubs from all over the USA and also provides information that might be useful for those who want to know about the moon and the solar system. This activity offered by the Pacific Astronomical Society prove the reason why the moon has the stage
The full moon is the phases of the moon when the whole moon is illuminating the earth. This phase occurs when the earth is between the moon and the sun. About a week later, the moon entered the quarter of the lunar month. At this point, half of the moon can be illuminated from the ground, so the moon looks like a semicircle. When the moon moves between the earth and the sun, the side facing the earth is completely dark. This is called the New Moon Phase, and we usually do not see the moon at this point. Sometimes, you can hardly understand the outline of the new moon in the sky. This is because a part of the sun reflects off the Earth and hits the moon. Before and after the quarter moon phase are uplift and new moon phase. During the expanse of the lunar moon, the moon was illuminated more than half, but it was not full. At the new moon stage, the moon is considered to have less than half the brightness, having only one sliver or crescent shape.
Moon moves around the earth and changes the part we see, so the moon has a phase. It takes 27.3 days for the moon to circle the earth, but the phases of the moon (from the new moon to the new moon) is 29.5 days. When the moon moves around the earth, the earth moves about 45 million miles around the sun, so the month spends "catching up" an additional 2.2 days. The full moon nearest to the autumnal point is called "harvest of the month". Because it exists brightly in the night sky, farmers can work for a longer time in autumn and receive the benefits of spring and summer labor. Since that point is always late September, it is usually the full moon in September, its name will be in a few years, but the full moon in early October gained the title of "bumper harvest".
