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 Moon in the Signs

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

In the Composite Chart, the Moon represents how the couple processes and expresses feelings and emotions. It can also indicate the areas where the couple will experience the most drama! It indicates what the couple needs to feel supported and loved.

To properly assess the Moon, we look at the sign, house, and aspects the Moon receives. In this article, we will go over how the Composite Moon behaves in different signs.

Composite Moon in Aries

The placement of the Moon in Aries in a Composite Chart indicates this couple expresses their emotions in a direct and passionate way. They are open and honest with their feelings, and love to tease and flirt.

In this relationship, the couple may get irritated and angry at each other, only to forgive and forget moments later. Aries is a very fiery sign, but it does not usually hold on to grudges.

Together, the couple may be more energetic, impulsive, and selfish than when they are apart. They are spontaneous and motivated in each other’s presence. This would be a great placement for a couple who compete together, as they energize and inspire each other to do their best.

Composite Moon in Taurus

The Composite Moon in Taurus indicates a stable, consistent, secure relationship focused on comfort and material possessions. Financial security is linked to emotional security here. They are romantic, sensual and enjoy the finer things in life.

This couple might be quite stubborn and resistant to change. They are emotionally stable and practical when faced with relationship difficulties. These two will take their time to build a solid and secure relationship that will last, and can depend on each other in times of need.

On the downside, possessiveness and jealousy may be an issue in this relationship

Composite Moon in Gemini

This placement indicates a couple who bond emotionally through communication. It is easy for these two to share their feelings with each other.  They may feel they can read each other’s minds and complete their partner’s sentences.

These two will like to keep in touch throughout the day, and will want to share all the details of their lives with each other. They will simply feel better by talking to one another. This couple likes being on the go, and may enjoy many short journeys and road trips together. They pique each other’s curiosity and love trying new things.

Composite Moon in Cancer

The Moon is most at home in Cancer, so this placement indicates a relationship that is very focused on connecting emotionally. This couple feels very ‘at home’ with each other. They will naturally nurture and take care of the other.

They want to build a family and move in together. They feel very comfortable in each other’s homes and with each other’s families (as long as the Moon isn’t badly aspected). It might be difficult for this couple to talk through feelings objectively, as their emotional bonds are so deep. They are very protective of each other and their relationship.

Composite Moon in Leo

Couples who have Moon in Leo in their Composite Charts do not ignore each other! This couple gives each other the attention and ego boost they each need. They feel they are the main protagonists in a romantic movie.

Leo is a dramatic sign, so its combination with the emotional Moon could lead to some major ego clashes, especially if the Moon is not aspected well by other planets. This couple might also emotionally bond over children or creative pursuits.

They are a fun and flirty couple who value loyalty and devotion above all else. Together, they are very charismatic and attract a lot of attention.

Composite Moon in Virgo

This couple might have met at work, but either way, they love working with each other and completing tasks together. Being productive will bring the two of them close together. They bond over a shared love of health and animals.

While Virgo is not the most emotionally demonstrative sign, the couple will show love by helping each other, or doing something practical for the other. On the downside, this placement can also indicate an imbalance or inequity in the relationship. Perhaps one of the partners feels they are always “giving” in the relationship, while the other is always “taking”. Perhaps one person works for the other.

Finding balance is key in this relationship, or else one will feel taken for granted by the other.

Composite Moon in Libra

Partnership and commitment is easy for these two. When they met, they immediately felt smitten! The emotional health of this couple relies on balance, equality and cooperation. This couple notice when things feel unbalanced and unfair.

They are both willing to compromise and work together to create an equal union. The two of them feel like a true team. This is a great placement to have in a composite chart, since Libra represents love and partnership. They enjoy throwing parties and have an active social life.

On the downside, this placement can indicate passive aggressiveness and indecisiveness might be strong in this relationship. Others will see them as the ideal couple.

Composite Moon in Scorpio

The Composite Moon’s placement in Scorpio indicates an intense and deep relationship. There is an “all or nothing” energy in this relationship, with both partners demanding complete and total commitment and loyalty from the other.

This couple emotionally bonds over sex and intimacy. They do not keep secrets from each other and want to know everything about the other. Possible themes of jealousy and possessiveness may feature strongly here.

The relationship will be transformative for both parties, and breaking up will not be easy. They will trigger deep, subconscious feelings within the other, so this relationship is anything but casual. Others will find them intimidating and intense.

Composite Moon in Sagittarius

This couple’s emotional bonding is connected to travel, philosophy, and higher learning. This is a very fun couple who love to make each other laugh. They might have shared religious or cultural ties, or they may have met abroad.

Either way, expanding one’s faith and philosophy are highlighted in this relationship. The two of them feel more adventurous, open minded and positive when they are together. They are a light-hearted, fun couple who love to explore together.

They are more open-minded, jovial and generous when they are together than they are individually.

Composite Moon in Capricorn

Building something and achieving something together is key to the emotional health of this relationship. When it comes to resolving conflict, this couple is mature and practical. It may be difficult, or even awkward, to express deep feelings to each other.

This would be a great placement for business partners, given that Capricorn rules business. While not emotionally demonstrative, this couple can depend on each other in times of need.

Composite Moon in Aquarius

This couple expresses their emotions in an aloof, detached manner. They have a strong foundation of friendship. They treat each other as equals, and may bond emotionally over shared friends, clubs/groups, and long-term goals.

This is not the most emotionally demonstrative couple, but they truly ‘like’ each other. They encourage each other’s individuality and give each other plenty of freedom.

Composite Moon in Pisces

These two are very forgiving and tolerant of each other. They bring out each other’s compassion and sensitivity. They bond over music, arts, and spirituality. The couple feels most emotionally content when they are alone.

In some cases, the relationship might lack definition and boundaries can be quite loose, so it is important to be very clear and honest to one another. The couple may feel they have found their soulmate in the other person.

On the downside, this relationship might be somewhat unrealistic or overly idealized by at least one of the partners, so honesty and clarity are of utmost importance here.
