The moon, also called the moon, is close to the earth and is a familiar planet. In ancient times, people thought the moon would shine, but now it is estimated that there will be no misunderstanding. The moon is a cold sphere. Because of the tide, one side of the moon always faces the sun, and the other side faces the sun. And this planet is not a star, so it can't emit light and heat, but the moon is bright from the earth. Why?

It turns out that the moon has diffuse reflection effect. It is a dim planet itself, even covered with dust, and the environment is quite bad, but it can still successfully reflect light. The moon shines from different angles, and the surface of the moon is not smooth, so light can come to the earth from different angles. Although the moon can only reflect 7% of sunlight and be received by the earth, people can still see the moon clearly. The atmosphere above the moon is quite thin, which is very different from that of the earth. So if the sunlight comes to the moon, it can not only reflect the light successfully, but also absorb part of it, so everyone can see the beautiful glowing moon.
