Why does the Moon seem to change shape?

Half of the moon illuminated by the sun is bright because it is illuminated by the sun. Since the moon is orbiting the earth, we see different numbers of lit parts, so the moon seems to have changed shape. When the moon is between the earth and the sun, illuminated things are hidden from us. As it moves around the earth, more and more lit sides are in sight. Then it began to disappear again

The moon does not generate its own light - it only reflects light from the sun. As the moon moves around the earth, we see the sun illuminating the different parts of the moon. This results in a periodic change in the form of the moon called the phases of the moon. As the moon rotates around the earth, the illuminated part in front of the moon turns from completely illuminated to completely dark, and comes back again. The full moon is the phases of the moon when the whole moon is illuminating the earth. This phase occurs when the earth is between the moon and the sun. About a week later, the moon entered the quarter of the lunar month. At this point, half of the moon can be seen from the earth and illuminate the surface, so the moon looks like a semicircle. When the moon moves between the earth and the sun, the side facing the earth is completely dark. This is called the New Moon Phase, and you can not see the moon at this time.

Although the moon is bright in the night sky, it does not actually shine, it only reflects light from the sun. The shape of the moon you see depends on where you are on the earth and where the moon is in the earth's orbit. The moon starts with a complete circle (full moon) and completes the cycle, the contraction becomes almost invisible (new moon), then it expands again to the full circle; these phases are called phases of the moon (Figure 1 ). For details, see Mitchell et al. , 2008 for more information.

Okay, okay, that is why the moon changes shape. There is the moon, it looks like it is hanging in the sky, but in reality, it is traveling around the earth. Not only that, the earth is also rotating. Lost? No? Hello! Well, so the number of moons you can see on a sunny night depends on two things: It will be in that LUNAR CYCLE (about 1 month ... or "month" required!) And the place related to the sun is the moon. If you can see the moon facing the sun (even if it is our night), the light of the sun will shine it perfectly. It's a perfect moon
