Moon in Houses Synastry Meanings: 1st through 12th House

In synastry, the house the Moon is in will show the area of life that someone touches another on a deep and personal level.

Just as the Sun is the Luminary of the day, the Moon is the Luminary of the night.

It is commonly thought that the Moon governs emotions and intuition, and it does. It also governs much, much more, however. The Sun shows who we are, and the Moon shows what we do.

The Sun is the King or Queen of the chart, whereas the Moon is the Prime Minister. The Moon governs all of the day to day activities of our lives.

The area in our chart that is touched by the Moon of another person is the area where we are the most exposed. This is where the other can influence us the most strongly, which can be either positive or negative.
