Best Synastry Aspects for Marriage

When looking for the perfect soul mate to spend the rest of your life with, you will probably date more than one person. And, if you are lucky to hit it off with someone on the first date, the thought of marriage may cross your mind.

Have you ever wondered why is it that only a few people draw our interest, especially in a romantic way?

Well, having good chemistry is critical for any relationship to flourish. But, did you know that astrology can also determine if two people are the right fit for each other? A sub-branch of it known as synastry compares a map of the heavens when two people were born to determine how planetary forces can influence interactions between them.

So, does that mean it is possible to spot if two people are likely to get married based on information on their birth charts?

Admittedly, deciding to tie the knot with someone is ultimately an individual decision. However, there are a few best synastry aspects for marriage that signal the potential of a long-term partnership. Keep reading to learn what they are and discover which cosmic forces indicate whether you will enjoy being married to your partner.

Which Are The Best Synastry Aspects For Marriage In Astrology?

In synastry, a comparison of natal charts belonging to two people takes place. The process reveals the position of specific significant planets, which form interplanetary angels known as aspects. These alignments can create either ideal or difficult conditions for two individuals to get along with one another when they interact.

Negative aspects like square and opposition are potential red flags that bring friction to a relationship. On the other hand, positive aspects like trine, sextile, and conjunction create the right conditions for a relationship to thrive.

In this guide, though, we will focus on the best synastry aspects for marriage, which can have a connection to one or more of the following planets or points of astrological significance.

1 Sun/Moon/Ascendant Aspects


The sun, moon, and ascendant are three of the most significant components in synastry. That is because they influence the kind of impression and emotional reactions that emanate from the interactions of two people.

The moon represents your feelings, whereas the sun embodies who you really are or your personality. On the other hand, the ascendant influences the image you project to the outside world and how people perceive you. Having trine, sextile, or conjunct aspects between any of these placements suggests two people who will get along very well.

2 Venus Aspects

In Roman mythology, Venus is the goddess of love. Astrologers look to this planet to find out how anyone will approach matters of the heart.

When this planet forms harmonious aspects with another person’s birth chart, in all likelihood, that couple could end up loving each other eternally. The reason for this is because Venus indicates strong affection and attraction. Depending on which planet it is forming an aspect with, its energy can play out differently. For instance, a Venus conjunct moon synastry points to a lovey-dovey couple. If romance is important to you, then this is one of the best synastry aspects for marriage.

3 Mercury Aspects

Mercury is known as the “messenger of the gods” in astrology because it governs the day-to-day expression between people. When positively aspected, it supports good communication in a relationship.

A Mercury Trine Sun synastry suggests mutual understanding, which fosters respect in marriage. On the other hand, a moon-Mercury blend that happens to be in harmony brings together two people who share their feelings without fear in a supportive and caring way.

Any problem that married couples face, bet it about kids, money, intimacy, etc., can be addressed with honest, open communication. As a result, harmonious Venus aspects that foster dialogue can help in building a sustainable marriage.

4 Mars Aspects

Whereas Venus rules romantic attraction, Mars is the planet of physical attraction. In astrology, it has an impact on sex drive. Therefore, positive synastry aspects that involve Mars indicate a healthy sex life, which is one of the key ingredients to a fulfilling marriage.

The Moon conjunct Mars synastry suggests a steamy and passionate relationship. Besides physical attraction, this aspect indicates the existence of a strong emotional connection as well.

Venus trine Mars is also one of the best synastry aspects for marriage in astrology. It sparks passion between a couple that is romantically involved.

5 Vertex Aspects

In astrology, the Vertex is not a planet. Instead, this is a point where the ecliptic and prime vertical intersect in the western hemisphere (or right-hand side) of a natal chart.

Usually, the Vertex becomes activated when something destined to happen unfolds. As a result, it is a point of karmic or fated connection.

When it comes to relationships and marriage, the Vertex can tell us whether two lovers are fated to end up together. It is usually a special thing to see planetary connections (with the Moon, Venus, or Mars) forming positive aspects with another person’s Vertex.

6 Juno Aspects

Juno, one of the largest asteroids or mini planets between Mars and Jupiter, is another celestial body of astrological importance.

In Greek and Roman mythology, Juno was hailed for showing undying loyalty to her husband, Jupiter (also known as Zeus). That is why she is responsible for the pairing of soul mates. In astrology, Juno represents commitment, marriage, or the give-and-take in relationships.

A Juno-Venus synastry with soft aspects is an indicator of two people who would make ideal mates. Both natives will find it easy to commit to each other on a romantic level.

It is also common to find many married couples having other positive aspects with Juno with a conjunct or trine synastry alongside Mars, Venus, or the lunar North Node.

7 Relationship Planets Conjunct 7th House

Besides the intra-aspect alignments of planets on the birth chart, we can also look at other overlays that hint at the prospect of a satisfying marriage. A good example is when planets fall in the 7th house.

While this placement is not an aspect in the astrological sense, it is still significant in relationships. The reason for that is because the 7th house rules marriage and partnerships.

If the sun happens to fall in this section of your partner’s birth chart, they will view you as the ideal spouse. Also, if Venus activates their 7th House, they will admire the way you express your love. Usually, 7th House overlays are felt by the house person.

Bottom Line

Synastry can provide a lot of information regarding whether two partners are fit for marriage.

But, even as you turn to the stars for advice, keep in mind that the details you find are not necessarily cast in stone. The outcome of any relationship is up to the individuals involved because we all have free will.

That said, having the best synastry aspects for marriage can increase the chances of having a fulfilling and loving union.

So, take the time to explore what hidden secrets exist between your birth chart and that of potential dates. In all likelihood, favorable indicators might help you find the right match when looking for a life partner.
