Synastry contact
Moon Sextile Moon Synastry: When Your Feelings Fit Without Matching
Short answer: Moon sextile Moon synastry (comparing two birth charts) means that how each of you feels, your moods, needs and comforting habits, comes at things from a different side from the other's, and the two fit. Each of you has a Moon, so the contact is the same from either side. A sextile usually joins signs of two elements that suit each other, so it tends to read as a fit between differences: you often get on about feelings without feeling things the same way. "Raphael" in 1905 writes that friendship follows when the Sun or Moon in one chart is in a friendly aspect with the lights in the other. This page reads that as a tendency. Two inferences are the site's: that "the lights" covers Moon to Moon, and that a sextile is among the friendly aspects. The cost of a fit can be that it shows mostly when you do things together, and can slip out of view when you do not. It is one contact among many, and what gets built on it is up to the two of you.
Two Moons that fit
The Moon in a chart stands for the feeling side of a person: moods, needs, the habits that comfort them, and what makes them feel safe or at home when they are tired or hurt. Moon sextile Moon in synastry means your Moon and their Moon are about 60° apart in the zodiac. Each of you has a Moon, so the contact is the same from either side: your Moon and their Moon, their Moon and your Moon.
A sextile usually joins two signs of different elements that suit each other: fire with air, or earth with water. (Usually, not always: a sextile that starts near the edge of a sign can reach past the pattern.) That is why this contact tends to read as a fit between differences. You do not feel things in quite the same way, as you might with a trine, but your ways tend to fit together. What comforts one of you may not be what comforts the other, and the two often turn out to go well side by side.
It can turn up between friends, siblings, colleagues, flatmates, or a parent and their child just as well as between partners, and it is only one of many contacts in any two charts.
What it is like to share this
Because both of you have a Moon in this contact, there is no one who steadies and one who is steadied. Each of you is both the person being met and the one doing the meeting.
Living near someone whose Moon fits yours, but is not like yours, often means you see how they cope and find it useful. One of you may want company after a bad day and the other a task for their hands. Neither is wrong, and the two tend to go well together. You may pick up a habit from the other that you would not have chosen, and find it suits you.
A sextile tends to show most when you do things together: sharing a meal, sorting out a room, getting through a bad week. The ease is there, and it often comes when both of you take part. When one of you comes home flat or edgy, the other may respond in a way the first would not have chosen, and the first can still use it. Comfort from someone who feels differently can sometimes miss. Here it tends to be near enough to work.
What each gives, and what each may want
Put simply, each of you tends to give the other a different way of dealing with a feeling, one that suits their own.
What each of you may give without trying is a different way of being comforted. One of you may be good at saying nothing and staying close. The other may be good at changing the subject, or putting the kettle on, or going for a walk. Each of you tends to see the other's way work, and each may borrow it. You often leave the other's moods mostly alone, and you do not tend to mind that they do it differently.
What each of you may want in return is mostly to be taken in by the other's way: your feelings taken as real even when they are not the other's kind of feeling, and some room to deal with them at your own pace. These often matter to both of you. Here they can be easy to give, because the difference tends to be interesting, not threatening.
What the contact does not tend to supply on its own is a push. A sextile is friendly, not urgent.
How it might look
These are sketches, not reports: illustrations of how the contact might show up across different kinds of pairs.
- Flatmates. One of them gets in late after a bad shift and wants to be left alone. The other, who would have wanted company in their place, puts a plate in the oven and goes back to their room. Both find the evening went better than either expected.
- Parent and child. A parent and their child, now a teenager, handle a bad day differently. The parent likes to talk it over and the child likes to go quiet. One evening the parent asks one question and then starts the washing-up, and the child, drying beside them, starts talking after a few minutes.
- Colleagues. News of a team restructure comes out on a Monday. One colleague wants to hear every detail straight away, and the other wants to wait for it to settle. They split it: one reads the announcement, the other sleeps on it, and they compare notes the next morning.
- Siblings. Two siblings plan a holiday. One likes to have the days mapped out and the other likes to see how it goes. They agree on a fixed first night and a free second day, and both find they enjoy the weekend more than they expected.
- Friends. One friend says they would like a slow weekend. The other had hoped for a busy one. They settle on a long walk with no set destination, and both go home having had something that neither would have planned.
- Partners. One of them has had a draining few weeks and is flat and short with people. The other does not take it personally, and does the cooking in their own way, which is not the way the first would have done it. Neither would have described it as comfort, and both feel better for it.
In each sketch the same thing happens: one person's way of coping with a feeling is not the other's, and it still turns out to suit.
In fire and air, or earth and water
A sextile usually pairs two elements, so there are two main versions. In plain terms: fire is enthusiasm and action, earth is practical steadiness, air is talk and ideas, water is feeling.
Fire and air. This version tends to be quick and to run on talk and enthusiasm. One of you may feel things fast and want to act on them, and the other may want to say aloud what is going on. The feeling gets somewhere to go, and the talk gets something to be about. It might look like two friends on a long train journey: one gets cross about a delay and the other starts joking about it, and by the next station they have turned it into a plan for the evening.
Earth and water. This version tends to be slower and more about care. One of you may feel secure when things are solid and predictable, and the other may feel deeply and take on the mood of a room. The routine gives the feeling a shape, and the feeling gives the routine some warmth. It might look like two colleagues sharing an office in a hard week: one keeps the lists and the tea rota going, the other notices who needs a word, and between them nothing is missed.
What a fit costs
The ease is real, and it has a cost that belongs to two Moons that differ.
The fit shows in doing things together. In a stretch where you do not, such as a move, a busy year or a new job, the contact has less to show itself in and can slip out of view. Out of view is not the same as gone, but you may drift to treating each other as pleasant rather than close, since nothing is pushing you to find out how the other is.
Because the two of you are comfortable with each other's differences, you may not say what you feel as readily as you would if the differences were a problem. Each of you may assume the other has seen it, when what the other saw was a different way of coping that looked fine.
You may also find that the other's way of being comforted is not the one you would reach for, and that you sometimes give the version you would want. It often takes a second try. Neither of you is mistaken; the two ways are simply different.
None of this is a flaw in the contact or in either of you. It is what this kind of fit is like to live with, and it comes with a plain advantage: a feeling the other does not share is not usually a threat, so a hard thing may be easier to say.
From the sources
What the older sources say
Raphael (*The Guide to Astrology*, 1905, p. 96) is the source for this contact. He writes that if the Sun or Moon in one chart is in conjunction with, or in "friendly aspect" with "the lights in the other nativity", and that "then will friendship follow". His page prints the conjunction as a symbol, so that word is not quoted. (A nativity is the old word for a birth chart.) "The lights" is his word for the Sun and Moon. He does not say Moon to Moon: his line speaks of the Sun or Moon in one chart and the lights in the other. Reading it as covering Moon to Moon is an inference from its wording, not something he spells out. His "friendly aspect" is a general phrase and does not name the sextile.
Three more sources are used here as supporting, and each speaks of the luminaries (the Sun and Moon) in two charts in general, not of the Moon to the Moon. Alan Leo (*How to Judge a Nativity*, p. 221): "The luminaries in favourable accord in two nativities will produce sympathy". Vivian Robson (1922, p. 140) calls it "the strongest sign of affinity" when the luminaries in two maps are in conjunction or good aspect, which he says indicates "radical harmony". Ptolemy (Ashmand, 1822, pp. 192–193) says that where familiarity exists "only as regards the places of the luminaries", friendship is established by spontaneous will and is "the best and most secure". He means a bond through the luminaries by any of his kinds of link, not the sextile in particular.
Ptolemy also calls the trine and the sextile "harmonious" because they join signs "of the same kind" (Ashmand, 1822, p. 38, I.16). That is a statement about aspects in general, not about two people, and only the sign geometry is used here. Ptolemy's "kind" is masculine or feminine (the old names for the two halves of the zodiac, alternating sign by sign), which a sextile also joins. It is not element, so it does not separate a sextile from a trine either.
Raphael's "friendly aspect" does not name the sextile, and it is the site's reading that a sextile is among the friendly aspects. None of these sources tells a sextile from a trine: Raphael writes "friendly aspect", Leo "favourable accord", Robson "good aspect", and Ptolemy names the two together. The difference this page draws, that a sextile reads as a fit between differences because it usually joins signs of two different elements that suit each other, is this site's reading, based on the kinds of sign each aspect usually joins. The older books do not say it.
The sources state their readings flatly: the luminaries in accord "will produce sympathy", and "then will friendship follow". Reading that as a tendency, not a description of a relationship or a promise of how it turns out, is this site's reading. So is everything in the other sections about moods and habits, what each of you gives and may want, and what a fit can cost: none of the sources says it.
Ptolemy's chapter on marriage (p. 184) and the sentence after Robson's (p. 140) also give the contact a direction by the man and the woman, and Zadkiel's line on the Moon in the same degree in both charts (1861, p. 109, not cited here) is worded in terms of the sexes. This page does not use any of them, and the contact is described here for any two people. The sources give the contact no direction that is needed here, since each of you has a Moon.
Is this you two?
- You deal with a bad mood in different ways, and neither of you has found that a problem.
- What helps one of you is not quite what helps the other, and you have each learned the other's version.
- Something the other does when they are low has turned out to work for you too.
- You are at your easiest doing something side by side, not just sitting across a table.
- Now and then one of you says what is wrong twice, because the first time it looked like something else.
- In a busy stretch you can go a while without checking in, and pick up again without fuss.
