Moon

The Moon is the second luminary, governing mood, habit, memory, and needs for safety and belonging. Its sign shows emotional style; its houses shows where nurturing and fluctuation concentrate.

Because the Moon moves quickly, lunar sign is sensitive to birth time for exact degree and house, though sign usually remains stable within a two-day window. Lunar aspects color how feelings cooperate with reason (Mercury), desire (Venus), or drive (Mars).

The progressed Moon is a common timing technique — see progressions. Cross-chart, lunar contacts in synastry often describe comfort and domestic rhythm. Water-sign tone when placed in sign-cancer, sign-scorpio, or sign-pisces.
