Sun Sextile Sun Synastry: When You Go About Life Differently and It Fits
Short answer: Sun sextile Sun synastry, which means comparing two birth charts, finds your Sun (who you are) and theirs about 60° apart, usually in signs of two elements that suit each other: fire with air, or earth with water. Each of you has a Sun, so the contact is the same from either side: your sense of self, will and direction tend to go about things differently from theirs, in ways that still work together. It reads as a fit between differences, easy but best seen when you do something together. This page reads Raphael's line as covering Sun to Sun, and his "friendly aspect" as including the sextile; he says neither, and the sourced section says so. "Raphael" in 1905 writes that the Sun or Moon in one chart in friendly aspect with "the lights" in the other means "then will friendship follow". This page reads that as a tendency and says plainly what a fit can cost. It is one contact among many, and what gets built on it is up to the two of you.
Two Suns, about a sixth of the zodiac apart
Every chart has a Sun, and it does one job: it is who you are. It is the self you steer by, what you want, where you are heading, the energy you bring into a room. Sun sextile Sun in synastry means your Sun and their Sun are about 60° apart, a sixth of the way round the zodiac, give or take a few degrees.
A sextile usually joins signs of two different elements that suit each other: fire with air, or earth with water. (Usually, not always: one that starts near the edge of a sign can reach past the pattern.) That is geometry, and it is why this contact tends to read as a fit between differences. You are not the same, as in a conjunction. A trine usually joins two signs of the same element; a sextile usually joins two elements that suit each other. So the two of you tend to go about things in different ways that still work together.
Because both of you have a Sun, the contact is the same from either side: your Sun and their Sun, and their Sun and your Sun. There is no one who brings one thing and one who brings another. Each of you is both the one being met and the one doing the meeting.
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 have Suns that fit
For each of you, the experience tends to be of being met by someone whose sense of direction differs from yours and does not get in your way. You may want something quite different from what they want, or go about it differently, and still find that what they do helps. You do not have to win them round, and you often do not have to become more like them.
Suns that fit tend to lend each other something. Your will is aimed one way and theirs another, and the two directions can be put to use together. One of you may be bold and the other careful, one quick to start and the other good at finishing, and a plan built from both is often better than either would have made. Next week the roles may swap, and it can feel just as natural.
There is also a plain pleasure in being seen from outside. A person whose way of going about life differs from yours may notice what you are good at precisely because it is not what they do themselves. Praise from someone who can see your approach as an approach, not as the obvious way, often means a good deal.
What each gives, and what each may want
Each of you tends to give the other a second angle. In a Sun sextile Sun, giving and receiving run the same way, so there is usually little friction in it.
What each of you tends to give is a different route to something you both want. You can say "what if we did it this way?" and have the other see at once how that could work, even though it is not how they would have started. You tend to take their plans seriously because you can see what they add to yours. Your encouragement often fits, because it comes from someone who sees the point of what the other is doing without needing to do it that way.
What each of you may want in return is mostly to be invited in and thanked for the difference.
What this contact does not tend to supply, by itself, is the push to act. A sextile is easy, and easy things are often left undone. The two of you may agree that a plan would work and then not start it, because nothing between you is uncomfortable enough to force the matter. It tends to show when you are doing something together, and it may stay quiet when you are not.
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 you likes to plan the week on Sunday night; the other prefers to see how things go. The flatmate who plans finds that the list gives the other something to tick off, and the other's looseness keeps the list from taking over the evening.
- Parent and child. A parent is cautious about money and their grown child is willing to take chances. Neither tries to change the other. The child brings a business idea; the parent asks three questions that make it sturdier; the child goes away and uses them.
- Colleagues. A team lead hands a report to two colleagues. One is quick with the big picture, the other with the detail. In the first meeting they notice that each is covering what the other would have skipped, and they divide the work without either feeling the other has taken the better half.
- Siblings. Two siblings plan a surprise for a parent's birthday. One wants it grand and the other wants it simple. They land on a small gathering with one large gesture, and each thinks the other's idea made it work.
- Friends. One friend always suggests somewhere new, the other always knows a place that will be quiet. Between them the Saturday goes well more often than it does when either picks alone, and neither would say who is in charge.
- Partners. One partner mentions at supper that a job in another town has been advertised. The other has never wanted to move, but starts working out what it would take, and asks about schools and rent before anything else. The idea gets a fair hearing, neither pushed through nor waved away.
In each sketch the same thing happens: one person's way of going about things meets another way that is different in kind and fits all the same, so each makes use of the other.
Fire and air, 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. Which of you has which element hardly matters here, because the contact reads the same from either side.
Fire and air. One Sun is in a fire sign and the other in an air sign. This version tends to be quick and to run on talk and enthusiasm. The fire Sun supplies the wish to act and the air Sun supplies the words and ideas for it, and each tends to make the other's way of going about things easier to carry out. It might look like two friends on a long train journey who hatch a trip in the first hour and have argued it, cheerfully, into shape by the last.
Earth and water. One Sun is in an earth sign and the other in a water sign. This version tends to be slower and more about care. The earth Sun supplies a steady, practical way of going on, and the water Sun supplies feeling and a sense of what others need. It might look like a parent and their grown child on moving day: one handles the van and the paperwork, the other remembers the neighbours who need a goodbye and the box of things that must not be lost, and between them little is missed.
What a fit costs
The fit is real, and it has costs that belong to two Suns that differ.
First, the fit shows in doing things together. Over a stretch of not doing much side by side, 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, and it tends to come back when you take on something together.
Second, differences can look like gaps. The same angle that helps you can, on a tired day, seem like a sign that you want different things. One of you may start something in one way and find the other would have started in another, and wonder for a moment whether they are being second-guessed. Often they are not; often it is just the other's view arriving.
Third, this contact tends to show most when both of you take part. In a trine, likeness does much of the work; here the fit often needs both of you to use it.
None of this is a flaw in the contact or in either of you. It is what an easy line between two different people is like to live with.
From the sources
What the older sources say
Raphael is the one source behind this contact, and the other four quoted below are supporting: they speak of the luminaries (the Sun and Moon) in two charts in general, not of Sun to Sun.
"Raphael" (*The Guide to Astrology*, 1905, p. 96) writes that if the Sun or Moon in one nativity (birth 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. He writes of "the lights", so he does not spell out the Sun in one chart against the Sun in the other. Reading his line as covering Sun to Sun is an inference from its wording, not something he says. He does not say which aspects are friendly, so it is also the site's reading that a sextile is among them.
Supporting these, Alan Leo (*How to Judge a Nativity*, p. 221) writes that 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 (*Tetrabiblos*, trans. Ashmand, 1822, pp. 192–193) says that where familiarity exists "only as regards the places of the luminaries", the friendship 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. And on p. 38 he calls the trine and the sextile "harmonious", as they join signs "of the same kind". That is about aspects in general, not about two people. 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 the sextile from the trine. All of these speak of the luminaries (the Sun and Moon) in two charts, which can be read as covering Sun to Sun as well as Sun to Moon or Moon to Moon. That is an inference from their wording, not a point any of them makes.
None of these sources tells the sextile from the trine: Ptolemy names them together, and the others write "favourable accord", "friendly aspect" and "good aspect". 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.
They also state their readings flatly: "then will friendship follow", the luminaries "will produce sympathy". 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 this article about what each of you is like, what each gives and may want, the elements and what a fit costs: that is the site's own, and none of these writers says it.
Ptolemy's chapter on marriage (p. 184) and the next sentence in Robson (p. 140) also speak of husband and wife, or man and woman. This page does not use them. The sources give this contact no direction, and here none is needed, since each of you has a Sun.
Is this you two?
- You often get to the same goal by routes that differ, and each route turns out to be useful.
- Either of you can take the lead on a plan, and the other is happy to add to it.
- You do not have to be alike to work well together.
- You are at your easiest doing something side by side, not just sitting across a table.
- You can have a quiet stretch together, and the fit comes back as soon as you take on something shared.
- Now and then you both agree a plan would work and neither of you starts it.
