The Moon is the only natural satellite of our planet. Despite the fact that from Earth it is one of the brightest objects that we can see in the sky, its brightness is really a reflection of sunlight. Its presence in the night sky and its characteristic cycle has made it an important cultural influence in language, mythology or art. The lunar cycle lasts approximately 29 days and depends on the illuminated part of its area that we can see from Earth. Its phases range from the new moon, in which it is difficult to see, to the full moon, in which the lunar disk is fully illuminated by the sun. Our planet is also subject to its influence, an example of which is the tides strongly related to the moon and its different phases. When there is a full or new moon, the tides are stronger, however, the tides are softer when the moon is in quarter phases.
