Influence of the Moon & Moon Signs

Aries Taurus Gemini Cancer Leo Virgo
Libra Scorpio Sagittarius Capricorn Aquarius Pisces

The Moon’s proximity to the Earth combined with the fact it moves through the Zodiac much quicker than the other heavenly bodies (i.e., once a month) make its influence particularly significant. If you’re a Cancer, the Moon is your ruling planet and you’ll notice its influence even more. This is why Cancers are often moody, unless stabilized by an Ascendant, Moon or stellium (3 or more planets) in an Earth sign.

Your Moon Sign, determined by the sign in which the Moon resided when you were born, rules your core emotional nature. However, as your Sun Sign changes according to the explanation found under Progressed Charts, your Moon Sign also changes by the same principles. Particularly note that while it takes 30 years to progress through an entire Sun Sign, your progressed Moon Sign will change roughly every two to two and a half years.

The fundamental nature instilled by the Natal Sun and Moon Signs will affect a person for their lifetime at a very deep level. The affect of the aspects in the progressed signs are felt as well, somewhat similar to a person who is born and raised in Texas then later moves to another state. The person is still a Texan, but will experience new things and even adapt new behaviors based on the change. Thus, your Natal Moon will continue to rule your core emotions but the ones on the surface will be greatly affected by your Progressed Moon.

Moon Sign progressions can have a dramatic effect on a person emotionally. If you suddenly find that you’re reacting to situations differently than they’d affected your previously, chances are you recently changed. For example, if in the past you reacted to emotional situations mainly by talking them out, then suddenly find yourself less vocal, but easily moved to tears, chances are your Moon recently progressed from an Air sign to a Water sign. Or if you suddenly find yourself much more down to Earth about emotional subjects and less likely to get angry than before, you probably changed Moon signs from a Fire sign to an Earth sign.

Water signs (Cancer, Scorpio and Pisces) and Fire signs (Aries, Leo and Sagittarius) tend to be the most sensitive and ruled by emotion. Earth signs (Taurus, Virgo and Capricorn) and Air signs (Gemini, Libra and Aquarius) tend to be less emotional and more inclined to make their decisions based on logic. The affect these different reactions can have on relationships goes without saying, much less if someone suddenly changes signs and starts reacting entirely differently than they did before.

The Moon’s affect goes even beyond these core and behavioral influences. As the Moon travels through the Zodiac each month, it will pass through your Natal and Progressed Chart and conjoin every planet in each of them along the way, even if it’s only for a matter of hours. These influences are transitory and are barely noticeable. However, whichever House the Full and New Moon occurs in for you each month is going to have slightly more emphasis. For example, you’re likely to be a bit more egocentric than usual, much as you are when the Sun is transiting your Natal or Progressed Sun Sign, if there is a Full or New Moon in your 1st House. If a New or Full Moon occurs in your 6th House, you may start an exercise program or diet or possibly have something at work affect your more than usual. In the 4th House, you might put more energy than usual into fixing up your home, etc.

Lunar phases in astrology are known as lunations. The most common ones are the New and Full Moon, though the term itself refers to any of its many faces. Besides the Moon’s general influence as it transits your Houses or the added punch it gives when a lunation takes place in one of them, Full and New Moons in particular are also known to trigger aspects in your Chart that had previously been dormant. When major events occur in your life the chances of them having been triggered by a lunation are quite high.

In my experience, Conjunctions seem to have the most influence, where there is a New or Full Moon within one degree of a Natal or Progressed planet, with that planet possibly making an aspect with another.  Remember that the Moon moves through the Zodiac on a monthly basis so will be conjoining every planet every month, but when this occurs when the Moon is New or Full, you’re more likely to notice it. Ordinary horoscopes, even the personal ones available from our Reports page, don’t address Lunations. However, we have personal Lunation Reports available that directly address either the Full or New Moon and give you an idea of what themes to expect during the two-week period in effect following each one. Generally a New Moon indicates a beginning and a Full Moon an ending, though sometimes it’s easy to confuse the two since they’re usually intertwined, depending on the situation involved. If you have a copy of your Natal and Progressed Chart, you can see the position of the Moon and use our Lunation Table to watch for conjunctions or other significant aspects.

What triggered my study of the astrological influences in effect for the three major NASA accidents was the observation that they all occurred during NASA’s solar opposition. (All three occurred between January 28 – February 1, which is opposite NASA’s "birth" date of July 29.) Other NASA missions occurred during this time, however, and didn’t suffer any ill-effects. The difference, I found, was that lunations had triggered a Grand Cross aspect immediately prior to each of the three tragedies, which were all well over a decade apart. The well-known problems that occurred for the Apollo XIII mission occurred in April and various other aspects contributed to the fortunate ending.

As the Moon makes its trek through the Zodiac, there are various times when it makes no major aspects to the planets as far as the transits are concerned. These periods are referred to as "Moon void of course" and many astrologers have observed that anything attempted during these periods will usually come to naught and advise not scheduling any important events at that time.

There is also what is called the Lunar Return, which is when the moon returns to the exact location it was in when you were born, i.e. conjoins your natal moon.  This will occur roughly once each month.  A chart cast for this time will provide a "map" of what you can expect emotionally for the coming 28 days. 

Books have been written on the influence of the Moon astrologically and this is only intended as the most basic primer on the subject. However, the next time you look up at the Full Moon, you might ponder what tides it’s affecting other than the rise and fall of the oceans.
