Marriage indicators in the Composite Chart

The composite chart is an extremely insightful tool in astrology compatibility analysis. However, it can be difficult to determine the marriage potential of a relationship when you do not know what to look for!

I’ve studied many composite charts of married couples and have noticed some patterns I’d like to share with you.

Keep in mind: One aspect or placement will not determine whether or not you will marry someone; the full Composite chart must be analyzed. 




Having 3 or more planets conjunct in your composite chart is very powerful. The most powerful are conjunctions involving the composite Sun, Moon, Venus, Mercury and Mars.

The stellium is even more powerful when it is aspected by outer planets. I favor easy aspects from Jupiter, Saturn, Uranus, Neptune and Pluto to the composite stellium, but I see hard aspects just as often in the composite charts of married couples.

With hard aspects, the couple will face more challenges in their relationship, but the relationship can still be long lasting and committed.

Do you need a stellium in a composite chart for marriage? No; I’d say stelliums are ideal, but I’ve seen plenty of composite charts of married couples with more ‘spaced out’ planets (though, they usually have at least a couple of conjunctions). Other placements and aspects can certainly indicate marriage, as described below.

Ruler of the 7th house

The ruler of the seventh house is a very important planet to analyze in the composite chart. The seventh house represents formalized commitment, and gives clues in regards to the longevity of a relationship.

To determine your Composite 7th house ruler, check out the chart below:

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

A well-aspected seventh house ruler can indicate a relationship in which both partners are very committed to the relationship.

Here are some aspects I’ve commonly seen in the charts of married couples:

  • Ruler of composite 7th house conjunct, sextile or trine the ruler of the composite 1st house
  • Ruler of composite 7th house conjunct, sextile or trine composite Juno
  • Ruler of composite 7th house conjunct, sextile or trine composite planets (especially Sun, Moon, Venus, Jupiter and Saturn)
  • Ruler of composite 7th house conjunct the composite Angles (AC, DC, MC, IC)
  • Ruler of composite 7th house conjunct composite Vertex
  • Ruler of the composite 7th house conjunct composite North or south node
  • Ruler of the composite 7th house in Libra

Do you need a well-aspected 7th house ruler for marriage? In my opinion, YES! The 7th house ruler represents your love and commitment towards each other. The Composite 7th house ruler in square aspect to Saturn, for example, can indicate difficulty formalizing your commitment. A square from Composite Uranus to the Composite 7th house ruler can indicate an on-off, unpredictable relationship. A trine from Composite Saturn, on the other hand, can indicate longevity in the relationship, as well as formalized commitment (if the rest of the chart agrees).

5th and 7th house planets

The 5th house represents love, romance, dating, and creativity, so Composite planets in this house (especially Sun, Moon, Mercury, Venus, Mars and Jupiter) indicates a fun and dynamic relationship. There may be a strong desire to have children together, as well. Be sure to analyze the ruler of the Composite 5th house to determine whether babies are in the cards for you and your partner!

The 7th house represents commitment and partnership, so Composite planets in this house (especially Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn) can indicate a powerful connection. In this relationship, the couple feels like a ‘team’, and enjoy being around each other.

5th house and 7th house placements alone do not guarantee marriage, but they are nice additions and can increase the attraction and feeling of unity between the couple. 

Libra Planets

Some of the longest lasting relationships I’ve seen have Composite inner planets in the sign of Libra. 

Libra is the sign of love and partnership, as well as fairness, cooperation and harmony. When a couple has their composite Inner plants in Libra, they are natural partners for each other and find it easy to commit to one another. Being together just feels ‘right’.

I personally know 3 couples with challenging Composite charts, but they come across as the perfect couples and have stayed together for many years. What they all have in common is Composite stelliums in Libra (and their 7th house rulers were well aspected).

Placements to look out for:

  • Composite Sun, Moon, Mercury, Venus, Mars and/or North Node in Libra
  • Composite Ascendant in Libra
  • Ruler of Composite 1st house in Libra
  • Ruler of Composite 7th house in Libra

The Vertex is often referred to as the ‘point of Fate,’ so it is usually powerfully placed in the charts of married couples. It points to couples who are ‘meant to be’. 

Common composite Vertex aspects in the charts of married couples:

  • Composite Vertex conjunct Descendant
  • Composite Vertex in the seventh house (especially if conjunct or opposite a Composite planet)
  • Composite Vertex conjunct the ruler of the Composite house 1, 4, 5, or 7
  • Composite Vertex conjunct or opposite North Node
  • Composite Vertex conjunct Composite Juno, especially if in the 7th house

Composite to natal chart comparison

Comparing each persons natal chart to the Composite chart is a valuable tool in relationship analysis. It is important that both partners have strong inter-aspects with the Composite Chart to ensure mutual commitment. 

Here are a few examples of Composite-to-natal aspects you should look out for:

  • Composite Chart planets conjunct natal angles 
  • Composite Chart angles conjunct natal planets
  • Composite Chart North Node conjunct or opposite natal planets and angles (and vice versa)
  • Composite Chart Vertex conjunct or opposite natal planets and angles (and vice versa)
  • Conjunctions and oppositions between natal planets and Composite planets
  • House overlays to 1st, 4th, 5th, 7th, and 8th houses (Composite planets in Natal houses, and Natal planets in Composite houses)


This is not an exhaustive list, and I will continue to add to it as I discover more important aspects and placements.

Composite Venus in the Signs

The Synastry and Composite are the most important charts in relationship astrology.

In the Composite Chart, the Venus represents how the couple expresses love and what it values.  Venus also rules beauty, harmony, fairness, and material possessions.

This is a wonderful placement for Venus, as it feels very ‘at home’ in Libra. This couple expresses their love by always being considerate of their partner’s needs and wishes.

This couple is very physically affectionate and sexually active – it is as though they cannot keep their hands off each other. The love they feel for each other is consuming, obsessive, and all-encompassing.  They are very possessive over the other, which may lead to jealousy and insecurity. Loyalty and commitment are extremely important to this couple, for Scorpio usually brings an ‘all-or-nothing’ energy.

Affection is expressed in an friendly, detached manner.  This is not the most affectionate couple, but they truly ‘like’ each other as people.

Composite Venus in Pisces

Composite Venus in Pisces points to a relationship full of idealism, dreaminess, and at worst, delusions. When these two got together, there may have felt they had met their soulmate. They are far more sensitive, compassionate, and idealistic when they are together. It is as though they are living in some kind of beautiful dream. As Pisces is a very spiritual sign, the couple might take up meditation or go on a spiritual journey together. They see the best in each other and forgive one another easily.
