Planets & Astrology: The Moon

Security check! The moon shows what you need in order to feel “at home” in the world and in your relationships. According to astrology, la luna depicts the emotional forecast for your horoscope.

The ever-shifting moon has a powerful influence on planet Earth. It directs the tides and stabilizes our climate by regulating the wobble of the Earth on its axis. In astrology, the moon plays a similar role, directing the flow of our emotions and our internal temperatures. Someone with an Aries moon, for example, may heat up quickly, while a Scorpio moon is like an active volcano—their feelings simmering below the surface until they suddenly erupt!

Every heavenly body is said to “rule” a zodiac sign. The moon governs Cancer, the sign associated with women, the mother, the home and our general sense of security. Understanding your moon sign can help you navigate relationships with all the ladies in your life. It may also define how well you get along with mother. A Gemini moon, for example may be BFFs with your mom, while a Taurus moon may long for stability and consistency from dear mama. 

The moon changes signs every 2.5 days, transiting through all 12 zodiac signs in 27.5 days. Our changeable moods are governed by Luna—the Roman goddess who represents the moon. The moon is often thought of as the counterpart to the Sun: el Sol is expressive while la luna is receptive. The Sun’s energy radiates outward, while the moon processes all that heat and energy coming our way. What pushes your buttons? Where are you most sensitive? And how much emotion do you reveal? A measured Capricorn moon may view feelings as something to be controlled, while a compassionate Pisces moon may have #NoFilter, and weep openly at a moment’s notice.

Do you need a lot of verbal reassurance (Scorpio moon) or do you feel loved when people encourage us to take risks and shine (Leo moon)? Can you be comfortable with home on the road (Sagittarius moon) or do you require a well-appointed sanctuary (Cancer moon)? Even the way you save money or build a nest eggcan be revealed by the moon’s position in your chart.

Because the moon changes so rapidly, it’s important to know your exact time of birth in order to know your moon sign. Do your chart for free here.

Every moon sign has its own light side—the obvious feelings that we are comfortable with expressing.

Because the moon spins on its axis at the same speed that it orbits planet Earth, we can only glimpse half of her from our vantage point down here. There really is a dark side of the moon, and it’s not just the trippy name of a Pink Floyd album. This metaphor translates to the moon’s role in the chart. Every moon sign has its own light side — the obvious feelings that we are comfortable with expressing. And, then, there’s a dark side: the emotions that creep up and catch up by surprise; ones we may even try to reject within ourselves.

Understanding your moon sign can bring a deep sense of self-knowledge, but may also be a lifelong quest for understanding. Psychologist Carl Jung’s concept of the shadow definitely corresponds with this. To “know thyself” is truly a never-ending journey. Discovering the hidden facets of your moon sign is part of that path.

In Shamanic astrology, the moon even reveals your past life tribe — what core strength you bring into this lifetime. These may be traits that you’ve mastered and can use resourcefully, but should be mindful of not clinging to them as security blankets.

Knowing your moon sign is key to navigating your deepest desires and emotions. While you can’t change the moon sign you were born under, you can adjust the dials to help strengthen the positive traits. Here is a helpful guide:
