The Moon spends about two and a half days in each sign and takes 28 days to complete its journey through the zodiac.  It is the Earth's only natural satellite and controls the tides.  It was called Luna by the Romans, Mani by the Norse, and Selene by the Greeks.

The principle ruler of those born at night (nocturnal chart), it astrologically relates to one’s emotions and security needs.  It is your instincts, those primal stirrings that creep into your thoughts.  The natural ruler of Cancer, it has an influence on domestic and nurturing issues.  It represents the unconscious, the habits and instinctual behavior patterns we drift into when we are not operating from the realm of ego and consciousness (Sun).  She rules women in general, the mother or mother-figure in particular; and will describe (by sign, house, and aspects) how you experienced and perceived your mother.  The Moon is a very important influence in the chart and is looked at first, along with the Sun and Ascendant.  She represents sensitivity, moodiness, fluctuation, childhood and the patterns we learned in childhood, past conditioning, habits, how we seek to nurture and be nurtured, and the private life.
