The Earth’s moon is of course not an actual planet, but it is one of the “Big 3” most important objects in a birth chart. Your moon sign is the constellation that the moon lined up with at the time of your birth, which changes every 2-3 days. The changing moon comes out only at night, and as such it represents the side of yourself that you don’t always show to others. It represents your emotions and subconscious
mind, and how you connect with your own feelings. The moon sign and house can also indicate how you connect and respond to others emotionally, and in particular may shed some light on a person’s relationship with their mother.
