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 Charts: Who Feels What?

When two people come together, they create a relationship with its own identity and purpose. The relationship is represented by a couple’s Composite Chart.

When reading a Composite Chart, it can be confusing when trying to determine who feels what.

For example, the couple might have Neptune square Venus in the Composite chart. This aspect indicates a dreamy, sensitive, and rather idealistic relationship, but it also indicates an element of deception, delusions, or lies. In this case, who is the liar and deceiver?  In most cases, both partners will feel the energy, but one may feel more strongly than the other.

So, how can you tell “who is who” or “who feels more” in a Composite chart?

Check your Synastry

The Synastry chart will show you clues on “who is who” in the relationship chart. For example in the example above, the couple has Venus square Neptune in the Composite Chart. Now, check your synastry: do either of your Neptunes make harsh aspects to the other person’s inner planets?

If so, the Neptune person may bring an element of confusion to the relationship. If you both have harsh aspects from your Neptune to the other’s personal planets, confusion and deception may come from both parties.

Check your natal charts

If synastry doesn’t give you enough clues, take a look at each person’s natal chart. Say one of the partners has Neptune square their Ascendant, while the other has no prominent Neptune contacts. The natal Neptune square Ascendant person might bring the Neptunian energy to the relationship.

In addition, look at each person’s natal planet placements to see more. For example, if one of the partners has their Sun in Pisces, this can indicate they are the “Neptune” person.

If you have strong Uranus energy in your chart, check each partner’s chart for any hard natal Uranus aspects or Aquarius placement. For Saturn energy, check for Saturn squares and Capricorn planets. For Pluto, check hard natal Pluto aspects and Scorpio placements.

How do the Composite Chart Planets aspect your Natal Chart planets?

Comparing the natal charts of each person to the Composite Chart is a very effective way of determining who feels what in the relationship. In the example of the Composite Neptune-Venus square, check if either partner has a planet that makes a hard aspect to this square.

For example, your natal Sun might be conjunct the Composite Venus, which means it is square the Composite Neptune. This indicates you might feel the relationship is very loving (your natal Sun conjunct Composite Venus), but you may also feel the relationship is confusing, disorienting and hard-to-define, and may even impact your self-esteem (your natal Sun is square the Composite Neptune).

It is also important to check where the Composite planets fall in your natal houses. The Composite Sun falling in your first house indicates the relationship is good for your self-esteem and confidence, for example.

Here is an example: in my Composite chart with an Ex, we had Neptune square Moon in Aries. In my own chart, my Moon is in Aries, so I identified strongly with the emotional energy of the relationship. The square from Neptune, however, made me very confused about the relationship. My connection with him was very bizarre, and I never felt he was telling me the truth.

In his own chart, he has his Ascendant in Pisces square his natal Neptune, which can point to someone who isn’t completely honest. I think we both brought some Neptune energy into the relationship, but it came from him most strongly.  My natal Venus was also square the Composite Saturn, so I felt quite ignored and isolated in the relationship. Overall, it was a bad experience for me, and I was the one who ended things.

He, on the other hand, really liked our relationship. The Composite Venus fell in his first house, so he loved the way we looked together. He enjoyed the attention we got when we were out in public. He had a harder time with the breakup because he seemed to reap more benefits from it than I did.
