The Absolute Best Synastry Aspects

This article goes over the best synastry aspects when it comes to deep love, compatibility and long-term potential.

The Synastry Chart, in addition to the Composite Chart, provides much insight into overall compatibility of a couple. The Composite Chart represents the relationship itself and what the two of you create when you are together. Synastry, on the other hand, explains how two people affect and influence each other directly. Both are very important to consider in a relationship.

What are the absolute best synastry aspects for true partnership and compatibility?

 

Well-Aspected 7th House Rulers 

What is your 7th house ruler?

  • If your 1st house is in Aries, your 7th house ruler is Venus
  • If your 1st house is in Taurus, your 7th house ruler is Pluto
  • If your 1st house is in Gemini, your 7th house ruler is Jupiter
  • If your 1st house is in Cancer, your 7th house ruler is Saturn
  • If your 1st house is in Leo, your house ruler is Uranus
  • If your 1st house is in Virgo, your house ruler is Neptune
  • If your 1st house is in Libra, your house ruler is Mars
  • If your 1st house is in Scorpio, your house ruler is Venus
  • If your 1st house is in Sagittarius, your 7th house ruler is Mercury
  • If your 1st house is in Capricorn, your 7th house ruler is your Moon
  • If your 1st house is in Aquarius, your 7th house ruler is your Sun
  • If your 1st house is in Pisces, your 7th house ruler is Mercury

I’ve said it before, and I’ll say it again: the 7th house ruler for each partner is very important in synastry. The 7th house represents commitment and partnership, so you can tell a lot about a relationship when looking at how each person’s 7th house ruler is aspected.

  • One person’s 7th house ruler conjunct the other person’s angles
  • One person’s 7th house ruler conjunct the other person’s Nodes
  • One person’s 7th house ruler conjunct the other person’s Vertex
  • One person’s 7th house ruler conjunct the other person’s Juno
  • One person’s 7th house ruler conjunct the other person’s planets (Sun, Moon, Venus, Jupiter, Saturn, 1st house ruler, and/or 7th house)
  • One person’s 7th house ruler in the other person’s 1st or 7th house

Challenging aspects to the 7th house ruler can indicate barriers and difficulties in forming a partnership.

If your 7th house ruler receives a square from your partner’s Saturn, for example, it may be difficult to get the relationships off the ground. There may be obstacles and barriers to you being together.

If your Uranus is square your partner’s 7th house ruler, you bring an unstable and unpredictable energy to your partner’s area of partnership and commitment. Your partner likely sees you as someone undependable and erratic, and it may be difficult for you to make a full commitment to each other.

Personal planets conjunct the North Node (especially Sun, Moon, Venus or ruler of the 7th house)

If your planet makes a conjunction to another person’s North Node, there is a feeling that the two of you are heading somewhere together. Both partners can feel progress taking place when they are with each other. It’s a bizarre feeling to explain: it may feel uncomfortable, but it also feels right.

The planet person is guiding the North Node person towards their potential and encouraging them to come out of their comfort zone. This aspect tends to bind people together for a long time, for the feeling of fate is very strong.

What about the South Node? This CAN bind people together for a very long time, and usually does. However, the South Node is very draining, especially for the planet person, so it might not work out in the long run. Much depends on how comfortable each partner is with their South Node energies. Check out my South Node article to find out more.

Conjunction to Vertex (especially inner planets and angles)

So many long term couples have significant Vertex contacts in synastry, especially when they involve inner planets and angles. For example, one person’s Sun conjunct another person’s Vertex.

The Vertex is seen as a point of fate, so someone who has strong Vertex aspects with you impacts you powerfully. It feels like this relationship is meant to be, and you can feel this when you are together.

The Sun/Moon Midpoint

I’ve covered the significance of the Sun/Moon Midpoint in this article, however, it is worth repeating how important this point is when it comes to synastry analysis.

Aspects to look out for include:

  • One person’s angles in hard aspect to the other person’s Sun/Moon Midpoint
  • One person’s planets (especially Sun, Moon, Venus) in hard aspect to the other person’s Sun/Moon Midpoint
  • One person’s Vertex or Nodes conjunct or opposite the other person’s Sun/Moon Midpoint

Saturn 

Saturn is the glue that holds a relationship together, so it is important to have some Saturn aspects in your synastry (and Composite chart) to keep things stable and long-lasting.

Saturn can feel both limiting and rewarding, and this depends on how Saturn is handled by each partner in their own natal charts, as well as how their Saturns aspect each other’s planets and angles. People with heavy Capricorn or Saturnian charts may have an easier time with hard Saturn synastry, as they ‘expect’ and are used to things being difficult!

Sextiles, trines, and even conjunctions of one person’s Saturn to another person’s inner planets and angles promote longevity and responsibility in the relationship.

At the same time, I often see hard Saturn aspects in the synastry of successful couples, which can be surprising, given the harsh nature of the planet. In these charts, there are many other aspects which ‘soften out’ Saturn’s harsh edge (Jupiter and Neptune aspects especially).

Aspects to look for:

  • Saturn conjunct Sun, Moon, Venus, 7th house ruler, 1st house ruler
  • Saturn conjunct angles (especially Saturn conjunct IC)
  • Saturn conjunct North Node or South Node

House overlays in “relationship” houses

These houses are: the 1st house, 4th house, 5th house, 7th house and 8th house.

The 1st house represents one’s physical appearance and persona. If someone’s planets fall in this house, there is a good indication of attraction, or at least taking notice of you. Venus and Mars in this house are especially sexy.

The 4th house represents one’s home, family, and past. Someone’s planets in your 4th house indicates they impact you on a deep level. The 4th house is a watery, emotional house, so this person may bring you in touch with deep emotions.

The 5th house represents fun, games, and romance, so planets overlaying in this house indicates a strong bond between the individuals. The house person feels more romantic and flirty around the planet person, and there the two of them feel very good when they are together.

The 7th house represents partnerships and formal commitments, so it is no surprise that this house is important when it comes to relationships. When someone’s planets fall in your 7th house, you cannot help but want to partner with them in some way. You naturally want to build an equal and harmonious bond with them, and want their input in your decisions. They force you to look at the other side of the coin and see a different perspective, almost like they are a mirror to you.

The 8th house represents sex, intimacy, and passion, so this house is an important one to consider in synastry. When someone’s planets fall in your 8th house, they bring up very intense feelings from you. You cannot feel indifferent to them; there is usually a love-hate theme in the relationship. You love them passionately, but despise them equally when you feel upset with them. Sex and intimacy are taken to another level in 8th house relationships; you truly feel you want to merge with each other.

Please note: you should look at the house overlays of both partners. If you find that one person’s planets overlay onto your ‘relationship houses’, while your planets do not overlays onto their ‘relationship houses’, an imbalanced relationship can be indicated.

For example, if my Sun falls in your 8th house, you feel very strongly for me. I bring out very deep and intense feelings out of you, and you feel I have a transformative effect on your life. If your Sun falls in my 11th house, I might not feel the same way. I might see you as more of a friend than a lover, which might be devastating for you.

Sun conjunct Venus (trine, opposition, and sextile also work)

Venus represents love and beauty, while the Sun represents one’s essence and true self. Aspects between these two planets indicate love, pure and simple. This is not a wildly obsessive, romantic type of love, as it is commonly seen in the charts of good friends and family members. In a romantic relationship, however, this aspect is wonderful, for it increases the compatibility between you, and signifies that you really ‘like’ each other!

Moon or Venus in the same sign (i.e. Moon conjunct Moon, Venus conjunct Venus)

I’ve seen way too many of these aspects in synastry charts, so I had to mention them! The Moon represents our emotional nature, so when it is in conjunction to another person’s Moon, emotional compatibility is indicated.

The same can be said about Venus – these two express love in the same way, so it makes sense that they would be happy together. There is an intuitive understanding between them, and neither has to explain themselves too much. They just *get* each other.

Venus conjunct, sextile, or trine Pluto

I had to add Venus-Pluto to this list. It is the ultimate ‘Beauty and the Beast’ aspect, as it indicates the blending of love (Venus) and intense passion (Pluto).

Hard aspects can be hard to deal with, depending on your personality. Some people simply need drama and intensity in their relationships, so they can ‘handle’ hard Venus-Pluto aspects.

Softer aspects, however, are much easier to deal with. They inject a good amount of intensity and passion without being overwhelming. There is a deep love and intensity between the couple without the power struggles and intense jealousy that come with the hard aspects.

The conjunction is a very powerful aspect. It indicates deep desire, jealousy, obsession and love, and it all-consuming for both parties. This type of love transforms the couple, and they see each other as soulmates.

Mars sextile or trine Pluto

This aspect is another one of my favourites. The sexual connection in this case is off the charts!

Mars represents sex and energy, while Pluto represents intensity and passion. As you can imagine, the blending of these two planets indicates a lasting sexual connection.

In this relationship, sex is fulfilling and satisfying for both parties.

Sun conjunct Moon (trine, opposition, and sextile also work)

The Sun represents ones essence and personality, while the Moon represents our emotions and what makes us feel secure. Positive aspects between the Sun and Moon in synastry indicate a ‘marriage’ between the yin and yang. The Sun person feels supported and cared for by the Moon person, and the Moon person feels safe and loved by the Sun person. Together, they make a great team. The opposition is also potent in synastry because it indicates a lot of fascination and attraction between the couple. As they say, “opposites attract”!

Moon conjunct Venus (trine, opposition, and sextile also work)

I may be biased because I have had this aspect so many times (particularly the conjunction), but it is truly a magical connection to share with someone. This is such a sweet, caring and loving aspect. The two people feel very ‘at home’ with each other. Expressing your love and emotions to one another feels easier than usual. You bring out each other’s sweetness and vulnerability. This is such a perfect aspect to find in a synastry chart.

Venus conjunct Mars (trine, opposition, and sextile also work)

Interaspects between Venus and Mars are so spicy hot and deserve a spot in my list of best synastry aspects! These aspects indicate the blending of love with sex, leading to much passion and desire. I’ve found this aspect keeps the fire burning between a couple for a very long time, which is so important when it comes to keeping a relationship fresh. Sex is satisfying and usually quite frequent. The two of you intuitively know how to turn each other on, and can barely keep your hands off each other.

Marriage Indicators in Synastry

Which Synastry Aspects indicate marriage?

Determining marriage from a synastry chart can be challenging. Sometimes, “obvious” marriage indicators (i.e. planets in each other’s 7th house) fail to predict a couple’s future. After studying several synastry charts of married/long-lasting couples, there were a few aspects which stood out to me. 

 

Squares to the North Node:

These aspects are said to be indicators of star-crossed lovers. The nodal axis represents our life’s path: the South Node represents “where we’ve been,” while the North Node represents “where we’re going.”

Squares to this axis in synastry indicate an instant feeling of familiarity and attraction to one another. It may be difficult for each person to resist the pull of the relationship. The planet person may be part of an unresolved issue the North Node is carrying from the past, and must resolve in this life.

Some examples:

  • Angelina Jolie’s Moon and Mars square Brad Pitt’s North Node
  • Paul Newman’s Sun squares Joanne Woodward’s North Node, and Joanne’s MC squares Paul’s North Node
  • Victoria Beckham’s Moon squares David’s North Node, Victoria’s North Node squares David’s vertex
  • Linda McCartney’s North Node squares Paul McCartney’s Sun, Mercury, and Jupiter
  • Cash Warren’s ascendant is square Jessica Alba’s North Node
  • Prince William’s Pluto squares Kate Middleton’s North Node, Kate’s Mars squares Will’s North Node
  • Julia Roberts’ Mars squares Danny Morder’s North Node
  • Oprah’s North Node squares Stedman’s Jupiter
  • Bill Clinton’s Sun squares Hillary’s North Node
  • Frank Sinatra’s North Node squares Nancy Sinatra’s Moon and Jupiter
  • Ava Gardner’s North Node squares Frank Sinatra’s Sun, Frank’s Jupiter squares Ava’s North Node
Planets in conjunction or opposition to another’s Vertex:

The Vertex acts like a second Ascendant, while the anti-Vertex is like a second Descendant. The Vertex is often referred to as our “point of fate.” As a result, when someone’s planet or point conjuncts your Vertex or anti-Vertex, you feel drawn towards this person.

The relationship feels fated, and can indeed change your life. You feel destined to be together, and this feeling can easily last a lifetime. One person’s North Node conjunct or opposite another person’s Vertex are apparently very common aspects to find among married partners.

Some examples:

  • Angelina’s Venus/Ascendant conjunct Brad’s Vertex, Brad’s Ascendant conjuncts Angelina’s Vertex
  • Frank Sinatra’s Vertex opposes Nancy Sinatra’s Venus, Nancy’s Vertex opposes Frank’s Part of Fortune
  • Paul Newman’s Moon conjuncts Joanne Woodward’s anti-Vertex; Joanne’s Moon and Mars conjunct Paul’s Vertex. Their Vertexes are conjunct.
  • Victoria Beckham’s anti-Vertex is conjunct David Beckham’s Mercury and opposite North Node.
  • Paul McCartney’s Vertex is conjunct Linda’s South Node
  • Prince William’s Vertex opposite Kate’s Venus
  • Julia Roberts’ North Node is conjunct Danny Morder’s anti-Vertex; Julia’s anti-Vertex is conjunct Danny’s Sun and Mercury. In addition, Danny’s North Node is conjunct Julia’s anti-Vertex
  • Oprah’s Mars conjuncts Stedman’s Vertex, Stedman’s Neptune is conjunct Oprah’s Vertex
  • Hillary Clinton’s Vertex is opposite Bill Clinton’s Moon
Part of Fortune:

I was surprised to see how often conjunctions and oppositions of one person’s planets or points to another person’s Part of Fortune occurred in the charts of married couples!  The Part of Fortune (POF) is the synthesis of a person’s Ascendant, Sun, and Moon, so perhaps it should not be so surprising.

The POF is a point that indicates good fortune. When another person’s planets or points conjunct or oppose your POF, they will likely help you increase your wealth and happiness, and achieve your goals. According to Robert Hand, the POF is also an indicator of the physical body and its relationships with the social world. Thus, it makes sense that POF aspects in synastry are often found in the synastry charts of married couples.

  • Joanne Woodwards’s POF is conjunct Paul Newman’s Sun
  • David Beckham’s Sun is conjunct Victoria’s POF, and David’s POF is conjunct Victoria’s Mars and Saturn
  • Paul McCartney’s POF is conjunct Linda’s Moon and Venus
  • Cash Warren’s POF is conjunct Jessica Alba’s Jupiter/Saturn conjunction
  • Prince William’s POF is opposite Kate Middleton’s POF, Kate’s POF is conjunct Wills’ North Node
  • Danny Morder’s POF is conjunct Julia Roberts’ Mercury, Danny’s Vertex is conjunct Julia’s POF
  • Stedman’s POF is conjunct Oprah’s Jupiter, Oprah’s POF is conjunct Stedman’s Sun, Mercury, and North Node
  • John Lennon’s POF is conjunct Yoko Ono’s POF
  • Hillary Clinton’s POF is opposite Bill’s Mercury and Saturn
  • Frank Sinatra’s POF is conjunct Nancy’s Anti-Vertex
  • Ava Gardner’s POF is opposite Frank Sinatra’s Sun and Mercury
Sun-Venus or Venus-Venus synastry aspects:

Sun-Venus contacts in synastry are highly touted by astrologers, and for good reason! When this aspect appears in synastry, the couple feels affection and love for one another. If these contacts do not show up in synastry, Venus-Venus contacts can be substituted.

When one person’s Venus contacts another person’s Venus, your love styles are similar. You easily get along, and instinctively know how the other person wants to be loved. The conjunction and opposition are most potent, and the trine and sextile are powerful, as well. These aspects indicate instant love and affection for one another, as well as a feeling of joy when you are together. These aspects can indicate a love that lasts forever. When this aspect is mutual, the love is even stronger.

  • Angelina’s Venus opposes Brad’s Venus
  • Paul Newman’s Venus sextiles Joanne’s Venus
  • David Beckham and Victoria Beckham have a Venus/Sun sextile double whammy
  • Paul McCartney’s Venus is opposite Linda’s Venus
  • Prince William’s Venus trines Kate’s sun, Kate’s Venus biquitiles Wills’ Sun
  • Danny Morder and Julia Roberts have a Sun/Venus bi-quintile double whammy
  • Stedman’s Venus is sextile Oprah’s Sun
  • John Lennon’s Venus is opposite Yoko’s Sun, Yoko’s Venus trines John’s Sun
  • Frank Sinatra’s Venus squares Nancy Sinatra’s Sun, Frank’s Sun squares Nancy’s Venus
Venus/Saturn Aspects :

Saturn aspects in synastry are described as « relationship glue ». Saturn is the planet of commitment, while Venus is the planet of Love. As such, couples who have strong Venus-Saturn aspects (especially double-whammies!) in their Synastry charts have little problem committing to each other. These relationships are usually long-lasting.

  • Joanne Woodward’s Saturn conjuncts Paul Newman’s Venus, Paul’s Saturn trines Joanne’s Venus
  • Victoria Beckham’s Saturn is conjunct David’s Venus, David’s Saturn is trine Victoria’s Venus
  • Cash Warren’s Saturn trines Jessica Alba’s Venus, and her Saturn sextiles Cash’s Venus
  • Julia Roberts’s Saturn conjuncts Danny Morder’s Venus, Danny’s Saturn quincunxes Julia’s Venus
  •  Oprah’s Saturn quincunxes Stedman’s Venus, Stedman’s Saturn trines Oprah’s Venus
  • John Lennon’s Saturn squares Yoko Ono’s Venus
  • Ava Gardner’s Saturn squares Frank’s Venus
