The moon is not fixed in one shape, its shape often changes whenever you look at it, as the Arab month is what determines the shape of the moon, and between one and 29 days the moon begins to change its appearance, consisting of eight different phases and beginning with a new moon that cannot be seen easily due to the light. The sun, which lands on the side of the moon facing away from the Earth, so in the following lines we review the full eight phases of the moon.
The first phase of the moon is the new one, and it is considered an invisible phase, as the moon then faces the illuminated side of the sun, and the night side faces the Earth. Then comes the second phase, which is called the waxing crescent, where the moon is just a piece of silver, when the illuminated half of the moon is far from Earth, with only a small part of our planet visible to us, after which comes the third stage, called the first quarter, and at that time the moon will be in a quarter of its evil journey and you will see its row illuminated.
The moon in the fourth phase is called the waxing gibbous, and at that time most of the moon becomes diurnal and visible, and at that time the moon appears brighter in the sky. Then comes the fifth phase, which is called the full moon and here it is closest to the illumination of the sun. Then comes the sixth phase which is called the paradoxical gibbous, and then the moon appears and begins its journey in On its way back to the sun, it also reflects the other side of the moon, so that the seventh phase appears and is called the last quarter, and the eighth is called the waning crescent.
