The astrology of relationships and compatibilities (synastry) is an old practice and even the art of studying the interaction or harmony in love by comparing two (possible) partners’ natal charts.
Each of the two personal birth charts is marked by the energies of the planets and zodiac signs specific to each partner.
In fact, in the natal charts of each of us, the same planets or astral bodies might be present, but their positions in zodiac signs, in an astrological house, and the aspects between them differ from one person to another.
When we interact with others, our astral chart’s particular energies have the potential to guide us to different relationships depending on the strengths of their natal chart. The result of this interaction is as complex and unique as our personalities.
Of course, the compatibility in love between different signs gives us guidance on how a couple’s relationship can evolve. Still, these predictions are general because there are many other decisive factors in assessing two unique individuals’ suitability.
The basics of relational astrology are intuitive: two people are compatible if their Sun signs belong to the same element (fire, air, water, or earth). It is favorable for the Moon of the two people to be found in signs that again belong to the same element (fire, air, water, or earth). But is that enough? Well, the answer is NO!
The Sun has a remarkable effect in the synastry because, depending on it, the zodiac signs in which we fall are configured.
They are divided into four categories according to the element that characterizes them. Aries, Leo, and Sagittarius are zodiac signs of the fire; Taurus, Virgo, and Capricorn are earth signs; Gemini, Libra, and Aquarius are zodiac signs of the air; Cancer, Scorpio, and Pisces are water signs.
Between the zodiac signs belonging to the same element, there is a tendency for a high affinity. Moreover, air and fire zodiac signs show increased compatibility between them, as it happens between those of earth and water. The elements have a significant role in estimating a potential couple relationship, but the Sun does not. It is the only factor that indicates which element is predominant in the personality of a particular person.
The planets, each in one sign or another, can sometimes have a more significant impact than the Sun in this regard. If, for example, the Sun is in a water sign, but most of the planets are positioned in zodiac signs of fire, a person characterized by this astral conjuncture may be to a greater extent under the sign of the element fire.
If your partner does not have the same predominant element as you, it is necessary to be as tolerant as possible of the differences of opinion and feelings that may arise between you.
Love relationships are affected and influenced by several planetary aspects.
VENUS – the Goddess of Love
Venus gives us valuable information about how we approach heart problems.
Venus masters romantic love, but it also plays a role in our pleasant attachments, in a more general sense.
Venus represents the language of our love, the way we feel loved, and the way we offer our love.
MARS – The God of War
Mars, in the astrology of relationships, is the planet of the expression of desires and sexuality.
While Venus dominates the romantic attraction, Mars indicates a greater need for sexual assertion and manifestation.
MERCURY – The sphere of our mind and thoughts
Mercury tells us how we communicate with our partner, how we think, and whether or not we are intellectually stimulated by our partner in the sphere of relationships and love.
Sometimes our attractions make sense.
When the Venus, Mars, and Mercury of you and your partner are in the same zodiacal element (fire, air, water, or earth), it can create a high compatibility, good chemistry and a durable relationship.
Because when a person’s Venus coincides as a zodiacal element with the Venus of the possible partner, the same language of love appears, the same way of feeling and offering love and affection.
When Mars has the same element as the possible partner, the same way of acting, the same style, and sexual appetite are highlighted and felt.
When Mercury has the same element as its partner, then the same way of thinking, of communicating is highlighted.
Our attractions make sense on the scrutiny because we manifest with our partner the same way of feeling, thinking, and manifesting. We feel the same, we have the same beliefs, and we in the same way. – Perfect harmony!
At other times, our attractions seem completely IRRATIONAL.
At least once in your life, you felt a strong attraction to an inappropriate person for us.
Maybe you got into a relationship with such a person, and everything turned into chaos, or perhaps everything went perfectly, and the relationship was very harmonious.
Each person is impregnated and influenced by the natal chart’s energy, the strength and positions of the planets and other astral bodies at birth.
When we talk about compatibility and relationships, when someone approaches another person, the energies of the two partners’ birth charts begin to merge.
This merger can be a success, or it can be a failure.
This process of merging the partners’ natal charts determines an energy exchange between individual planets of person A with certain planets of person B. This is where the adventure begins!
Here are some examples:
There is an energy exchange between Mercury and Mars.
Mercury in the square or opposition to Mars: generates tension and irritation between partners. Lack of mutual understanding and conflict.
Or maybe Mercury, following this astrological fusion of natal charts, is in conjunction, sextile or trine with Venus. Then the partners have a good understanding, common values and intellectual interests — a very favorable astrological aspect.
Or maybe one partner’s Venus (affection, love) comes into conjunction with the other partner’s Mars (strong sexual desires and manifestations), creates a strong physical and magnetic attraction, gives rise to passionate love and mutual sympathy.
Or Venus in the square or opposition to Mars: Compatibility and sexual attraction, but this astrological aspect generates jealousy and possessiveness between partners. The square between Venus and Mars is conflicting and does not allow lasting unions (except with great effort from both partners).
And that’s how complicated we are as humans.
Also, JUNO plays a significant role in compatibility and in attracting the partner.
Juno represents, in astrology, the marriage, respectively, the type of partner we will have. However, the asteroid represents more than that: Juno also indicates our desire to have a fulfilled, happy relationship.
Whether it is marriage or other types of relationships (cohabitation, friendship, etc.), it shows us, for example, whether we tend to have monogamous relationships or not. Suppose we get involved in stable relationships or prefer fleeting adventures, if we agree to be dominated by our partner and so on. People with a strong Juno in their natal chart, for example, will look for stable, long-lasting relationships.
On the negative side, Juno influences the partner’s addiction, infidelity, and the frustrations born when we fail to reach that much desired “fusion.”
For example, the native with Juno in Scorpio can become manipulative and jealous, using sex as a way to control his partner, who is subjected to permanent tests of fidelity and devotion.
Juno in Capricorn is engaged in relationships and traditional. The partner is wanted in the “business class,” sober, serious, mature, responsible, eager to achieve high social status and a stable material situation. So, Juno in Capricorn talks more about the social expectations we can have from our partner than emotional ones. The danger is that relationships can be a kind of loneliness for both of them.
On the other hand, Juno in Pisces tells us that the ideal partner is sensitive and romantic. Juno in Pisces wants a unique, spiritual connection with her partner.
Juno’s transits produce important relationship-related events, such as marriage, separation, or divorce.
