Moon (astrology)
Encyclopedia
The Moon is the Earth's companion satellite. The Moon is large enough for its gravity to affect the Earth, stabilising its orbit and producing the regular ebb and flow of the tides. The Moon is also familiar to us for its different phases
Lunar phase
A lunar phase or phase of the moon is the appearance of the illuminated portion of the Moon as seen by an observer, usually on Earth. The lunar phases change cyclically as the Moon orbits the Earth, according to the changing relative positions of the Earth, Moon, and Sun...

, waxing and waning in appearance in an unchanging cycle. For this reason, astrologers consider the moon to be at least secondary in importance to the sun
Sun (astrology)
The sun is considered a very important part of astrology. It, as well as the Moon, are the most important of the astrological planets, and the two of them are often referred to as the luminaries. In Greek mythology the sun was represented by Apollo, the god of light, and Helios, the god of the sun...

 in astrological terms, and it is widely considered to be just as important as the sun.

The Moon orbits the earth in 28 days, spending a fleeting 2.33 days in each of the signs of the zodiac. Recently, more accurate measurements of the Lunar orbital period have revealed two different numbers, depending on viewpoint. The synodic period is measured relative to the Sun and gives us a period of 29.5 days from new Moon to new Moon, the start of the Lunar month. When observed from the Earth and relative to a fixed point in space, the sidereal period is 27.3 days with minor variations. In order to give a figure in whole numbers for ease of astrological calculation the Lunar orbit can be approximated to 27.75 days which then returns a period of 54 hours or 2.25 days for the Lunar transit of each sign.

Also important in astrology are the moon's nodes

s can occur. The North node marks the place where the moon crosses from South to North (or ascends), while the South node marks where the moon crosses from North to South (or descends). The nodes' motion is always retrograde, so that they appear to move backwards through the zodiac

In astronomy, axial precession is a gravity-induced, slow and continuous change in the orientation of an astronomical body's rotational axis. In particular, it refers to the gradual shift in the orientation of Earth's axis of rotation, which, like a wobbling top, traces out a pair of cones joined...

, but in the case of the moon it only takes 19 years to complete a cycle. The two nodes are always exactly 180 degrees apart from each other at opposite ends of the ecliptic (i.e. if the north node is at 23 degrees Aries, the south node will be at 23 degrees Libra).

The moon is also said to represent receptivity, vulnerability, etc. but this should not suggest that its power is considered less than the sun's. From an astrological perspective (in which we assume, for the sake of argument, that the earth is fixed and everything else moves) the sun and moon are the same size. From an astrological perspective, they are equals; a solar eclipse reminds us of this so that we do not doubt the power of the moon, which is hidden and mysterious but no less influential.

The first-century poet Manilius, described the Moon or Luna, as melancholic. In medicine the moon is associated with the digestive system, stomach, breasts, genitals, buttocks, the ovaries and menstruation, and the pancreas. The moon is the ruler of the 4th house.

Lunar phases

Astrologers traditionally also consider the phase of the moon at the time of birth in interpreting its effects on the individual. The four phases of the moon are as follows:
First quarter (new):Astrologers say a person born in the first phase of the moon will have an underlying sense of youthful enthusiasm and optimism, a touch of the zodiac sign Aries
Aries (astrology)
Aries is the first astrological sign in the Zodiac, which spans the zodiac between the zero degree and the 29th degree of celestial longitude. The Sun enters Aries when it reaches the northern vernal equinox, which is usually on March 21 each year, and remains in this sign until around April 20...

 in their nature. They will probably prefer to take the initiative, especially in romance, and will be ready to look for new interests in life, new people and new ideas. The person will see how things can be improved and can spur others to action, before leaving them to finish the project. They will probably get off to an early start in life and be quite successful when young, though other factors in the chart will indicate whether this success is lasting. They need to guard against selfishness and taking others by surprise with over quick and hasty reactions.
Second quarter (waxing):Astrologers say a person born in the second quarter will be ambitious and sociable, with an underlying touch of the zodiac signs Cancer
Cancer (astrology)
Cancer is the fourth astrological sign in the Zodiac. It is considered a water sign and one of four cardinal signs. Cancer is ruled by the Moon. Individuals born when the Sun is in this sign are considered Cancerian individuals...

 in their nature. The person will be locked into their goals and have a strong need to create something which will be remembered by others. They will have a charismatic personality that draws others to them, but may instinctively use others for their own ends, rather than help them. They prefer a career where they are out in front and have attention and status. They also need a place of their own to express their personality, either their home or workplace. The person should achieve considerable success when young, but other factors in the chart will indicate whether that status is maintained. The person will be slow to anger, but formidable when aroused, and hates to be hurried or presented with a fait accompli. However, they won't mind doing this to others if it tips the odds in their favour.
Third quarter (full):Astrologers say a person born in the third quarter will be sensitive to the needs of others and expects others to be sensitive to their own needs. There is an underlying sense of watchfulness reminiscent of the zodiac signs Libra

. The person will need friendships, colleagues and relationships, and will relate well to others. They will either be drawn to highly successful people and help them achieve their goals, or else achieve success themselves with the help of others. There is a tension and nervousness at play which can lead to a short attention span and a constant search for new people and experiences, and sex will play some kind of transformative role in their life. The most successful time of life will be in the middle years.
Fourth quarter (waning):Astrologers say a person born in the fourth quarter will have an underlying feeling of the zodiac signs Capricorn and Pisces. They will finish the projects that others start, and reorganize and sort out the problems left by others. They will often have clairvoyant insight and follow hunches rather than be logical. The person can be too sensitive and become upset by the demands of others, and can also be too inclined to sit back and let things happen. They will work best in groups and are not materialistic, but they do need job satisfaction. They may be slow to grow up, but are likely to go through some kind of metamorphosis later in life and achieve success in something unusual and completely individual.

Lunar nodes

While they are not considered by Western astrologers to be as important a factor as each of the planets, the lunar nodes are thought to mark sensitive areas that are worth taking into account.

– North or ascending Node

:The North node is said to tend to be beneficial in its effects, not unlike the planet Jupiter, and a possible source from which to derive some advantage, often through no conscious effort. Some astrologers consider the north node to represent a person's karmic task in the present life.
– South or descending Node

:The South node is said to tend to be somewhat adverse in its effects, not unlike the planet Saturn, and a possible source of the draining of energy from the person. It may indicate effort or even sacrifice is required, often without any expected reward. Some astrologers consider the south node to represent a person's karmic task in a past life.

Many astrologers also believe that there is a relationship between social and anti-social behaviour and compatibility and incompatibility and the placing of the nodes. This can be assessed by sign and house. The nodes also have some bearing on premises, property and domestic circumstances. Planets which progress

Void-of-Course Moon

A void-of-Course Moon occurs when the moon in transit makes its final major aspect before it changes from one sign of the zodiac to the next. It ends when the moon enters the next sign. In astrological terms it is a period when human judgement is impaired, ventures are bound to fail, business deals collapse, journeys are delayed, and historic events during such periods have an unusual impact on cultural evolution. People born on a void-of-course moon are said to be highly original and impressionable, who "bear the spark of greatness". They react differently to life and its challenges. On the negative side, they can have an unfavourable effect on the lives of many people with their irresponsible behaviour and erratic personality.
