Celestial Objects: The Phases of The Moon

Since the beginning of history, celestial bodies have always been wonderful. The moon, the stars and all visible things have been studied for thousands of years, and millions of people have dedicated themselves to research these wonderful things for decades. Not only the moon is the subject of research, it is also an infinite discovery, and for many other people, the moon is a goddess. According to Donald J. Frederick, the ancient civilization like the Maya considers moon to be a female entity and worships the moon for pregnancy.

One of the oldest fields of astronomy and all science is to measure the position of the celestial body. Historically, accurately understanding the positions of the sun, the moon, the planet, and the stars is essential for celestial navigation (using celestial navigation) and calendar creation. Carefully measuring the position of the planet provides a good understanding of gravity disturbance and the ability to determine the past and future positions of the planet very accurately This area is called celestial mechanics. Recently, NEO 's tracking will enable prediction of near - Earth encounters or potential collisions between the Earth and these objects.

The moon is a celestial body always adhering to the earth - even during the day. Is it only a white circle appearing (almost) every night, or has another purpose? First of all, it helps our ancestors guide in a great many ways through the stage of using it. The problem is how the Earth looks if there is no moon. We all know that the sea level goes up and down, and this phenomenon is called a tide. When the gravity of the sun and the moon dances with the earth, the tide falls. When the earth rotates around its axis, the sea water is drawn inward by the gravity of the earth and the centrifugal force is pushed outward and stabilized. However, the attraction of the moon is enough to destroy this stability and "swells" the water. As the earth rotates around the orbit of the moon, this bulge moves with the earth.
