Why do we see the moon?
In outer space, the moon is the closest fellow traveler of our planet. This is our only satellite rotating in orbit around the Earth.
Here is the most basic answer to the question of why we see the moon. Such a large astronomical body, so close to our planet, cannot be unnoticed by the human eye. By the way, this is the only extraterrestrial space that has been visited by representatives of the human mind. But this is too simple an explanation of the phenomenon of the appearance of the closest and largest satellite of our planet.
Every month she makes her journey around the earth. It is noteworthy that the consecrated side of the Moon, on which the sun's rays fall, is visible to the human eye, but the second side of the Moon, on which such rays do not fall, is not visible to us. Here is the answer to another very common question about why we see one side of the moon, and the other is inaccessible to the eyes of man. It is the reflection of sunlight from the surface of the moon that we owe to the fact that we see this light.If the Sun had not shone on it, we would hardly have seen it at all in the sky.
But the answer to the question of why the moon is visible during the day is also quite simple. It is visible because of the Sun, whose rays reflect its surface. Moreover, it does it very well, and in the daytime it is not illuminated by itself. Most of all, it is visible in the daytime, when it is with the Sun on opposite sides of the horizon. With a maximum approach to the main star of our system, it is not visible in the daytime.
By the way, the position that the Moon occupies in its orbit relative to the Earth will also determine what part of the illuminated half of this planet will be visible to us.
Visually, it seems to us that as it moves in orbit, the Moon changes its shape. Different forms of this planet, noticeable to the human eye, are called phases. The full cycle of such phases fits in 29 and a half days and constantly begins again.
