Why do we see the moon?

In outer space, the closest companion of our planet is the Moon. This is our only satellite, orbiting the Earth.

Here is the most elementary answer to the question:why we see the moon. Such a large astronomical body, so close to our planet, can not be unnoticed by the human eye. By the way, this is still the only extraterrestrial space that was visited by representatives of the human mind. But this is too simple an explanation of the phenomenon of visibility of the closest and largest satellite of our planet.

Every month she commits her journeyaround the Earth. It is noteworthy that the consecrated side of the Moon, which receives the sun's rays, 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 view of man. It is the reflection of sunlight from the surface of the moon that we owe to seeing this luminary. If the Sun were not shining on it, we would hardly have seen it in the sky at all.

But the answer to the question of why the moon is visiblein the afternoon, is also quite simple. It is visible because of the Sun, whose rays reflect its surface. And, she does it very well, and in the daytime it is not illuminated by himself. Most of all, it is visible during the day when it is with the Sun on different sides of the horizon. With the maximum approach to the main star of our system, it is not visible at daylight.

By the way, depending on what position the Moon occupies in its orbit relative to the Earth, it will depend on which part of the illuminated half of this planet will be visible to us.

Visually it seems to us that as far asorbiting, the Moon changes its shape. The various forms of this planet, which are noticeable to the human eye, are usually called phases. A full cycle of such phases fits in 29 and a half days and constantly begins again.
