Conclusion
Wouldn’t it be quite convenient if we could simply compare our astrological sun (star) signs to our prospective ‘significant other’ to determine whether we are a right fit for each other? While many factors play a role in choosing ‘the right’ companion, there’s a simple (astrological) way to find out if you and your partner are compatible: synastry.
This article examines the best marriage aspects in synastry and how these aspects are measured, as well as answers to FAQs.
What Are Aspects in Synastry?
In essence, aspects are connections between celestial bodies within a chart or between celestial bodies in multiple charts.
The astrological definition of ‘aspect’ includes interplanetary angles—angles that planetary forces form to each other on the wheel of an astrological chart. When two planets are 90° from one another, for example, they form a square because a square has four 90° angles. These mathematical relationships—based on the position of planets—affect us in a unique way.
It’s of great importance to look at astrological charts (here’s some astrology 101), separately, before reading the synastry aspects. This is because ‘houses’ are extremely important in synastry chart overlays; these are like permanent transits and can be misleading when looking at synastry aspects in isolation.
There are ‘applying’ aspects (planets moving together) and ‘separating’ aspects (planets moving away from each other).
Synastry aspects can show either ideal or difficult conditions in a relationship of two individuals.
Synastry Aspects for Marriage
A synastry (relationship astrology) chart reading measures the quality of the interactions of two natal charts, to provide a general understanding of how compatible two people are and how they respond to each other.
Any kind of relationship can be analyzed with a synastry chart. These readings, however, are usually done to determine marriage compatibility. And even though holding a wedding can be tricky this year, many decide to take the big step after carefully reviewing these.
Key Synastry Chart Aspects
Each aspect is important in attaining an overall picture of relationships. The basics, however, are the most significant in determining long-term, relational expectations of a couple, which include the trinity signs of the Sun, Moon, and Ascendant (Rising), as well as the sexual planets (Venus and Mars) and social planets (Saturn and Jupiter). |
North Node and Vertex connections are significant for karmic astrologers. Their aspects are believed to be one of the prime indicators of marriage in synastry and signal both challenge and growth. These connections indicate that two people are destined to meet because they have much to learn from each other. |
The Best Synastry Aspects for Marriage
In this part, you’ll read about a comparison of two individuals’ natal charts. This process will reveal the position of certain planets, which will help you see positive or negative aspects.
Sun/Moon/Ascendant
The ‘Sun/Moon/Ascendant’ aspects in synastry help you understand how couples interact (and react) to each other, including what kind of impressions they give and how they perceive one another.
The Sun
Is your deepest ‘self’, representing your identity. It shows the basic parts of your personality, how you experience life, and how you express your individuality.
The Moon
Represents your inner emotional landscape, your feelings, and your intuition. It’s your guide in deciphering a person’s emotions and shows how you nurture and care for others, as well as how you want to be treated.
The Ascendant
Exemplifies your social personality. It dictates the first impression you give to others and your outlook on the world.
Good ‘Sun/Moon/Ascendant’ aspects are great marriage indicators in synastry because they show whether a couple’s personalities match, i.e., if there’s good chemistry and if there are more instinctive emotional differences or similarities between the two.

Sun/Sun
A good ‘Sun Conjunct Sun’ synastry aspect indicates that a couple is on the same page—you and your partner understand one another on a more personal level.
The ‘Sun Trine Sun’ Aspect and the ‘Sun Sextile Sun’ Aspects
Are both great indicators of a successful marriage. They show you energize and support each other. Even if the Suns are in opposition, ‘Sun Trine Sun’ is still considered one of the best synastry aspects for relationships and marriage. Although the two of you have some basic differences in your personalities, you’re still attracted and intrigued by each other. If you both are willing to work on your relationship, there’s no reason why you shouldn’t thrive together.
‘Sun Square Sun’
In synastry reveals a dynamic relationship, where the couple challenges each other but can also be harsh to one another in response to a lack of understanding.
Moon/Moon
These synastry aspects are important for a significant relationship.
- ‘Soft’ Moon aspects in a synastry chart, such as trine, sextile, or semi-sextile, indicate an instant emphatic bond between partners. They show you have similar emotional sensibilities and feel quite comfortable with each other. It will be easy for the two of you to create a cozy, secure home environment.
- ‘Hard’ aspects suggest that it will be more difficult for the two of you to be emotionally in sync. It will take time to adjust to each other and become more understanding of one another’s needs—but once you do, you’ll be able to enjoy life together.
Sun/Moon
‘Sun/Moon’ aspects are considered the best synastry aspects for love. The Sun and Moon are the yin and yang in astrology because they complement one another.
- A ‘’Sun/Moon’ conjunction represents a powerful relationship, but it can be problematic. Similarly with sextile and trine, the Moon person generally relies on the Sun person, who emerges as the leader of the relationship but depends on the support of their partner. The trine and sextile ‘Sun/Moon’ aspects project a more compatible pairing, where the couple feels like they can rely on each other.
The square between the Sun and Moon in synastry is challenging, while the opposition is less problematic, due to a likely balance effect. Despite the potential to bring friction, all ‘Sun/Moon’ aspects are believed to be good marriage aspects in synastry.
Venus/Mars
Venus determines the way you approach relationships, romance, and love. In a synastry chart, this is indicative of strong affection and attraction. Mars, however, reveals how you express your sex drive and how you go about getting what you want.
- These aspects are good in a synastry chart—regardless of whether they are ‘hard’ or ‘soft’—because they indicate passionate love, with great sexual and physical attraction. While these attributes are not necessary for a great marriage, they’re thought to be among the best synastry aspects for a relationship of any kind.
Couples with ‘soft’ Venus/Mars aspects in synastry can quickly learn to deal with their differences and more easily adapt to each other. Those with ‘hard’ aspects will have more of an edge and excitement, coupled with occasional clashes.
Saturn/Jupiter
Another great example of how two planets can complement each other is seen in Saturn and Jupiter. These are quite different from each other. But in a birth chart compatibility analysis, they both bring value and potential to the relationship.
- ‘Saturn/Jupiter’ synastry suggests a highly productive relationship and marriage, with Saturn providing the stability and Jupiter the fun. Their relationship might not be easy, but if successful, they can make a powerful couple. As long as your long-term goals are aligned, this is an excellent combination of marriage aspects in synastry.
Sun/Moon Midpoint
The ultimate marriage aspects in astrology are the ‘Sun/Moon’ midpoint aspects. Astrologers say these represent the ‘inner marriage’ and show relationship fulfillment and closeness of the partners.
- The ‘Sun/Moon’ midpoint is a degree that—when activated by transit or progression—suggests major changes in the relationship. It signifies that you are in an extremely important relationship, which, consequently, is challenged with disruptions.
The activated ‘Sun/Moon’ midpoint doesn’t necessarily have to be reciprocated by the partner. If all this is starting to sound a bit confusing, you can always schedule a psychic reading and find it all out from a professional.
North Node
The ‘North Node’ (or ‘Ascending Node’) is one of two Nodes of the Moon, representing the path you are moving forward on. It’s out of your comfort zone but makes you feel fulfilled and purposeful.
- ‘North Node’ synastry aspects indicate that you feel that you and your partner are destined to be together because you’re moving in the same direction and come from a similar place.
- If your North and South Nodes conjunct, you feel inspired by one another. But a ‘North Node Trine North Node’ means you’re both yearning for spiritual growth and can support each other to achieve it.
Other good indicators for marriage are ‘North Node Conjunct Vertex’, the ‘Luminaries,’ ‘Ascendant,’ Venus, or Mars.
Vertex
Vertex aspects are the synastry aspects for true love.
- The ‘Vertex’ reveals a soul’s fated connections, regardless of whether they’re karmic relationships or not. When in transit or in progress (activated), this indicates that fated events are set to happen. This is the type of relationship that changes your life.
If you’re considering spending the rest of your life with your partner, any kind of ‘Vertex’ connection is in your favor. Its variations show the kind of relationship you have with your partner, which are all good marriage aspects in synastry. When your ‘Vertex’ is in the same house or planet as your partner, the aspect suggests an overwhelming attraction. It’s important to know things about karmic contacts and karmic relationships.
Did You Know: The German astrologer, Harald Hoffmann, created a list of different inter-aspects, he called ‘killer aspects’, because they’re considered to be detrimental to a love union. While a ‘Venus Trine Mercury’ synastry is a good sign, ‘Venus Semi-square Mars’ aspect is on Hoffman’s list. |
Key Takeaways
An isolated synastry reading, on its own, can be deceiving. It’s best to first look at the natal charts, separately, to avoid any confusion. |
All aspects are important in a synastry reading, but the basics (Sun, Moon, Ascendant, Venus, Mars, Saturn, and Jupiter) are the best indicators of a successful marriage. |
‘Sun/Moon’ synastry aspects are the most common aspects of marriage in synastry because they show how well a couple works together, emotionally and personality-wise. |
The ‘Venus/Mars’ synastry charts indicate physical attraction and sexual chemistry, eminently coveted, especially for the long haul. |
A ‘Vertex’ aspect in a synastry reading is considered good news, regardless of its type. |
How Are Aspects Measured?
Aspects are measured by the angular distance between two points (such as that of between two planets), from 0 to 360 degrees:
- A square aspect is at 90°;
- Opposition (180°)
- Quincunx (150°)
- Conjunction (0°)
- Semi-sextile (30°)
- Trine (120°)
Synastry aspects can vary in degree. For example, if the angular distance between Mars and Venus is 95°, it’s still considered a ‘square’ aspect but with an orb of 5° (given that it deviates 5° from an exact square). The same applies if the angular distance is 85°. The smaller the orb, the stronger the aspect.
Astrologers divide the astrology chart into 12 signs of 30°, each. From this point of view, a square aspect (90°) will be between planets that are three signs apart.
What Are ‘Hard’ and ‘Soft’ Aspects in Astrology?
How Do They Affect Synergy?
When analyzing synastry aspects, their interpretation is based on whether they are ‘soft’ or ‘hard’. Each planetary ‘meet-up’ (in terms of aspects) is different, but aspects are divided into two categories that show whether they would bring harmony or struggle to a relationship.
Aspects can be ‘soft’ (easy) and ‘hard’ (difficult/challenging). ‘Soft’ aspects are sextile and trine, while ‘hard’ aspects include semi-sextile, square, quincunx, and opposite. A ‘conjunction’ aspect doesn’t really fall into any category, since it can move in either direction, depending on the planet involved.
The table below lists the seven major aspects. Their allowable orbs are between 5° and 6°. Minor astrological aspects include smaller allowable orbs, between 2° and 3°.
The Seven Major Aspects | Hard Aspects | Soft Aspects |
Conjunct (same sign)
Semi-sextile (1 sign apart) Sextile (2 signs apart) Square (3 signs apart) Trine (4 signs apart) Quincunx (5 signs apart) Opposite (6 signs apart) |
Square
Opposite Quincunx (Inconjunct) |
Trine
Sextile Semisextile Conjunct |
The Effect | Brings friction to a relationship. | Creates the right conditions for a relationship to thrive. |
A ‘Sun Trine Mercury’ synastry, for example, indicates mutual understanding and respect in marriage. But a couple with ‘Sun Square Mercury’ synastry will likely experience strong tension because of a clash of egos and differences in communication.
Did You Know: No matter how compatible marriage aspects are, you need to first learn to love yourself before you can love someone else. Some crystals, like rose quartz are recommended for anything related to the heart chakra. You can try spreading rose quartz energy in your home with a love lamp or any form of rose quartz crystal. |
Do All Astrologers Calculate the Aspects in Synastry the Same Way?
Each astrologer uses different techniques to calculate the angular distance between two planets. This means that if you go to two astrologers to get a synastry reading of the same astrological chart, the aspects will likely be at different angles—though they should not greatly vary. If you have a ‘Juno Conjunct Venus’ synastry, for example, it will still appear in both readings.
Conclusion
Aspects in synastry can be good indicators of the prospects of a relationship and whether two people are a right fit for romance or marriage. Many astrologers propose scrutinizing the synastry chart aspects before taking the big leap and deciding to get married. Once the stars align, however, we can help you choose the right wedding registry and top wedding loans for bad credit.
There are many aspects that can tell you whether you’re a good match for marriage, which are all of equal astrological significance. The ‘Sun/Moon/Ascendant’ synastry aspects and the ‘Venus/Mars’ aspects are good places to start when considering relationships.
Note: The cosmolabe—an ancient astronomical (navigational) instrument, formerly used for measuring angles between planets—was once used to measure aspects. It was created by the French mathematician and philosopher, Jacques Besson, in 1567.
FAQ
In any astrological chart, an orb is the deviation from the exactness of the aspect. For example, a trine is 120°—if two planets are 123° apart, they are in trine with an orb of 3°.
Reading a synastry chart involves the same methods used to read birth charts, which is by measuring and interpreting aspects. Astrologers have various approaches, but you can find an online tool that can help you create an entire synastry chart.
Synastry does not predict the determined path of a marriage or whether your partner is the perfect soulmate. It only maps out the terrain of your relationship. Excellent marriage aspects in synastry do not automatically translate into a perfect union. Both sides have to work on their relationship or marriage.
