The moon is not as full as it should be every day. This is because the Moon's position in relation to the Sun and the Earth is constantly changing as it rotates around the Earth, creating the various phases of the Moon that we see. The surface of the Moon is covered with craters, mountains and plains. The most famous are those “lunar seas”, although the name has “sea”, but in fact there is no water, just a darker color of the plains. There is also the Shizumi Base, which was visited by the Apollo program, and is one of the wonders of the Moon.
