Why Do We See Only One Side of the Moon?

Because the moon also orbits the earth. What happens if the moon does not rotate around its axis? Now, we face us on the other hand; two weeks later, the other side of the moon will face us as the moon orbits around the earth. This is a picture (Earth and moon should be spheres, of course it is not a square):

If the moon does not rotate around its axis after the moon enters the middle of the earth's orbit, the picture looks like this.

You can see the other side of the moon on earth (In the first picture, the earth is watching "m" of "moon", but in the second picture we see the word "moon"). "n")

What actually happens is that the moon rotates about its axis; it rotates exactly the same way as the orbits around the earth once a month. Therefore, after half a turn around the earth, the moon will also rotate around its axis by half. The correct second picture will be as follows.

This is another photo. After a quarter of the track (about one week from the original picture), the moon will rotate 90 degrees around its axis. This is as follows.

Again, although the "m" side of the "moon" faces the earth, the moon rotates around its axis and turns the "m" side toward the earth.

Therefore the moon rotates around its own axis for the same time it goes round the earth. That's why the same side of the moon is always facing the earth.

The simple answer (and the answer you may have asked before) is that you can only see one side of the moon. The moon rotates around the earth at exactly the same speed as its own axis, and the moon is always facing the ground. This means that the day of the month (meaning the length of time it takes for the month to go around) is about 4 weeks. If the moon does not rotate at all, you can see all its edges, but the only way you can see such a constant lunar surface is when it is spinning. There is a good visualization below

When the moon and the sun are on both sides of the earth, we think the moon has been completed. But when the sun and moon are on the same side of the earth, we say the moon is "new". During the new moon, the aspect of the moon we can see from the earth is not exposed to direct sunlight at all. Between the new moon and the full moon, the moon is a new moon (less than half is illuminated). Then the wax - will grow - it will be a half moon (half illumination). At that point the month is one quarter of the cycle of the month, so the first half of the month following the new moon is called the first quarter. After the first quarter, there was a rising month (more than half had been illuminated), and lastly there was a full moon

Technically, the moon does not have a real 'dark side'. As I mentioned above, the moon has not yet been seen but it is still spinning but from our point of view the other side will still be exposed to the sun on that day "Sun." Indeed, the "dark side" of the moon is really completely dark only when we see the full moon.

If it is already dark you will notice that the moon has suddenly disappeared. why? The moon does not emit light. As the sun is reflected, we only see the moon. When the sun shines on the moon, the moon will disappear! The same is true for many other celestial bodies in the sky, such as planets. Only the reflected light of the sun can be seen. The upper layer of the frozen sea isolates the underground deep water and keeps them liquid for hundreds of thousands of years, but as the Earth moves to the Earth's average temperature of about -400 ° F, they eventually freeze To do. At this point, the atmosphere freezes and lands on the earth, exposing everyone to severe cosmic radiation across the universe.
