At the outset, it should be noted that the moon does not produce its own light. It only reflects sunlight from its surface. Therefore, if sunlight reflects off the moon’s surface, you can see it also during the day.
The visibility of the moon during the day depends on its angle and its distance from the ground. It is visible during the day when it is on the same side of the earth as the sun. When the sun and moon are on opposite sides, we will not see the moon during the day.
One may also ask why the moon is visible during the day and not the stars? The answer is very simple – the moon, although it is not shining in itself, the light reflected from its surface is about 100,000 times brighter than the brightest star in the sky.
An interesting fact is that we will not see the full moon during the day. A full moon occurs when the sun shines freely on its surface. If the sun is shining on the earth, it is daytime, which means that at least some of the sunlight is obscured by the earth. Therefore, we will not see a full moon during the day.
