Natal aspects

Sun aspects

What the tradition holds about the Sun at an angle to each of the other bodies. An aspect on its own is geometry; what the older sources actually discuss is a particular pair at a particular angle, and they treat each one as its own subject.

32 pairings curated here, each traced to a work and a page you can open for free. 32 also have a longer piece on what the pairing looks like in a life. Anything involving Pluto is absent and will stay absent: it was discovered in 1930, after every work this site is able to cite.

Sun and Moon

Sun conjunct Moon
Sun conjunct Moon means your sense of direction and your emotional instincts are fused into a single voice rather than two competing ones. You were born at or near a new moon, and that concentrated energy stamps the sign you carry it in so deeply that people often read it before they read anything else about you. The consistency can feel like a gift — you rarely war with yourself — but it also means your blind spots and your strengths arrive in the same package.
What this looks like in a life
What the source says: A Sun–Moon conjunction is the new moon, so this is a birth within about a day of one. One 1918 reading holds the sign the two lights share to be so strongly marked in the person that even a careful astrologer may mistake it for the rising sign.

Sun sextile Moon
Sun sextile Moon is the aspect of a person who rarely has to translate themselves. What you feel privately and what you present outwardly tend to line up without much effort — you do not often catch yourself performing a version of yourself that you quietly disagree with. That coherence makes you easy to trust, easy to be around. You tend to know what you want without needing to argue yourself into or out of it, which is quieter and more useful than it might sound.
What this looks like in a life
What the source says: Sixty degrees apart — roughly five days past the new moon. A good aspect between the lights is associated with paternal harmony and the favour of the family, of superiors and of employers.

Sun square Moon
Sun square Moon means you're rarely at rest inside yourself. The drive to go after something and the pull to hold back don't take turns — they arrive together, so a clear yes on Monday can feel genuinely uncertain by midweek. You start things with real momentum, then find the follow-through harder to locate than the initial push. This isn't inconsistency for its own sake; it's what happens when wanting and needing point in different directions at the same time.
What this looks like in a life
What the source says: Ninety degrees apart — a birth at the first or last quarter moon. One 1918 source reads a square or opposition between the lights as a vacillating, changeable disposition — rash to plunge into untried ventures, without the persistence or continuity of purpose to carry anything to a successful conclusion.

Sun trine Moon
Sun Trine Moon means your inner world and outer direction are speaking the same language. Where other people sense a constant negotiation between what they want and what they need, you more often find these two pointing the same way. Your instincts back up your decisions rather than quietly sabotage them, and the face you show the world does not cost you much to maintain. That ease can be invisible from the inside — you may simply assume everyone moves through life this way. They do not.
What this looks like in a life
What the source says: A third of the circle apart, about ten days past the new moon. A good aspect between the lights is associated with good home conditions and esteem in the community, and is said to favour a rise in life on the strength of the person's innate ability.

Sun opposite Moon
Sun opposite Moon means you arrived at the full moon — two lights facing each other across the sky, and you carry that tension inside. The part of you that acts and the part of you that feels rarely want the same thing at the same time. You can be entirely sincere when you commit to something and then, almost without noticing, begin pulling away. That is not weakness. Both sides of you are loud, and they take turns winning.
What this looks like in a life
What the source says: A Sun–Moon opposition is the full moon, so this is a birth at or near one. One 1918 source reads a square or opposition between the lights as a vacillating, changeable disposition — rash to plunge into untried ventures, without the persistence or continuity of purpose to carry anything to a successful conclusion.

Sun and Mercury

Sun conjunct Mercury
Sun conjunct Mercury means your mind and your identity are essentially the same thing — not a tool you pick up, but the self you move through the world as. You form opinions quickly, hold them with conviction, and feel personally implicated when your ideas are challenged. Silence reads as absence. You talk to think, think to exist, and rarely separate what you believe from who you are. The gift and the friction both live right there, at that same point.
What this looks like in a life
What the source says: The only aspect these two can form, and a common one: Mercury never strays far from the Sun, so a large share of all births carry it and having it distinguishes little. Alan Leo reads it as adaptability, resourcefulness, and the power to fit the environment or rise above it as needed, provided the sign suits both. One 1918 source calls it good for memory and mentality unless Mercury sits within three degrees of the Sun — then it calls the planet combust, its good qualities burned up in the Sun's rays.

Sun and Venus

Sun conjunct Venus
Sun conjunct Venus gives you a particular gift: you make things feel good without trying. Not the loudest presence, not the most dramatic, but the one people relax around. You gravitate toward beauty — in music, in aesthetics, in the company you keep — and you tend to offer warmth generously, sometimes before you have reason to. The challenge is that this ease can become a kind of avoidance, a preference for the pleasant that quietly sidesteps anything harder to sit with.
What this looks like in a life
What the source says: The only aspect these two can form — one 1918 source notes Venus never reaches a sextile, trine, square or opposition to the Sun — and a common one, so having it distinguishes little. Alan Leo separates the Sun approaching Venus, which he reads as love of pleasure, generosity and warm feelings with social advantages, from the Sun separating from it, which he gives fewer social desires and a more temperate nature. The same 1918 source adds a fondness for music, art and poetry, and an ease in company that wins friends and keeps them.

Sun and Mars

Sun conjunct Mars
Sun conjunct Mars gives you a charge that most people around you can feel before you've said anything. You move fast, commit hard, and throw yourself into new ventures with a heat that's genuinely impressive — until the initial fire burns down and the next compelling thing catches your eye. You've probably been called intense, impatient, or too much. The drive is real; the question this pairing keeps asking is whether you can stay in the room long enough to see it land.
What this looks like in a life
What the source says: Alan Leo reads this as great force of character and a hasty, fiery temper that does not last — a love of enterprise, and fits of ambition without the stability to carry them long enough to make success certain. Forceful, and often rash. One 1918 source groups the conjunction with the good aspects and adds a dauntless determination, executive and constructive ability, and a will that refuses to recognise defeat.

Sun sextile Mars
Sun sextile Mars gives you a particular kind of quiet toughness — not the kind that announces itself, but the kind that simply keeps going when most people would find a reason to stop. You take on commitments because you actually intend to meet them, and your energy tends to show up most reliably when the situation calls for follow-through rather than flair. The harder question, over time, is recognising which battles deserve that stubbornness and which ones don't.
What this looks like in a life
What the source says: Sixty degrees apart. Alan Leo writes on the conjunction, square, trine and opposition of this pair and not on the sextile. One 1918 source takes the sextile with the conjunction and trine, and reads the group as dauntless determination and courage in the face of long odds: given a plan to follow, the person can be trusted to carry it through, with executive and constructive ability and a will that refuses to recognise defeat.
Max Heindel, The Message of the Stars (1918), pp. 327–328 read it
Sun square Mars
Sun square Mars is the person who moves before the plan is ready, speaks before the room is ready, and pushes until something pushes back. You carry a charge that other people can feel the moment you walk in — not always comfortable, not always welcome. The engine runs fast by default, and slowing it down takes more conscious effort than it should. That same intensity is what gets things done, but it also picks fights you did not strictly need to have.
What this looks like in a life
What the source says: Ninety degrees apart. Alan Leo reads it as domestic worries, a liability to violent changes, and many troubles. One 1918 source treats the square with the opposition as an abundance of energy and a faculty for leadership turned to destructive ends: courage becoming foolhardiness, a loud and overbearing manner, a readiness to fight at the drop of a hat, and a standing opposition to whoever holds authority.

Sun trine Mars
Sun trine Mars gives you a rare internal alignment between wanting something and actually going after it. The hesitation, the second-guessing, the gap between impulse and action that trips so many people up — you mostly skip that step. When a goal takes shape, you move toward it without needing to talk yourself into it first. Setbacks register, but they rarely stop you for long. You are someone who finishes what you start, and that quality tends to define how others experience you.
What this looks like in a life
What the source says: A third of the circle apart. Alan Leo reads it as success through enterprise, industry, courage and adventure. One 1918 source takes the trine with the conjunction and sextile, and adds a dauntless determination and courage against long odds — given a plan to follow, the person can be trusted to carry it through, with a will that refuses to recognise defeat.

Sun opposite Mars
Sun opposite Mars gives you a presence that lands before you open your mouth — something in the posture, the pace, the readiness that other people clock immediately. You are not usually trying to take over a room, but the drive runs on its own schedule and rarely idles. What tends to follow is a recurring pattern: you push, something pushes back hard, and the collision arrives at the worst possible moment. Authority figures, sudden obstacles, and your own momentum are the recurring cast.
What this looks like in a life
What the source says: A hundred and eighty degrees apart. Alan Leo reads it as separations, powerful opponents and a career full of extremes, set against any permanent success by sudden and serious obstacles. One 1918 source treats the opposition with the square as energy and leadership turned to destructive ends: courage becoming foolhardiness, a swaggering manner, and a standing opposition to whoever holds authority.

Sun and Jupiter

Sun conjunct Jupiter
Sun conjunct Jupiter gives you a particular kind of gravity — the warm, self-assured kind that makes people assume you are always fine, always landing on your feet, always up for more. And often you are. The optimism is not something you switch on; it runs underneath everything, pulling you toward the bigger possibility, the broader horizon, the generous interpretation of events. The difficulty is that others sense this and quietly stop asking whether you need anything at all.
What this looks like in a life
What the source says: Alan Leo reads this as success through hope — the arrival of a teacher or helper, the favour of someone powerful, new social advantages or an unusual opportunity, and a name that grows through philosophy, religion or travel. One 1918 source groups the conjunction with the sextile and trine and describes a sunny and jovial disposition that earns friendship by acts of kindness, and a person everybody trusts because they never betray a trust.

Sun sextile Jupiter
Sun sextile Jupiter gives you a presence people welcome without quite knowing why. You say the thing that steadies someone, show up when a situation calls for encouragement, and move through the world with enough goodwill that others extend it back to you. None of this is performance — the warmth is just your default setting. What makes it last is the reliability underneath: people sense early on that what you say, you mean, and that what you know about them stays with you.
What this looks like in a life
What the source says: Sixty degrees apart. Alan Leo writes on the conjunction, the trine and the hard aspects of this pair, and not on the sextile. One 1918 source takes the sextile with the conjunction and trine, and reads the group as a sunny and jovial disposition, liked by nearly everyone met, earning that liking through acts of kindness and through words of sympathy, cheer or hope as the occasion may demand — and as someone trusted because they never betray a trust.
Max Heindel, The Message of the Stars (1918), p. 293 read it
Sun square Jupiter
Sun square Jupiter gives you genuine ambition and a large appetite for life, but the two rarely work in straight lines. You reach for more than feels comfortable to admit, then find that success tends to arrive by a side door rather than through the front. There is real warmth here and a talent for grand gestures, yet comfort and self-interest can quietly absorb more than you intend to give outward. The goal keeps expanding just as the path to it bends.
What this looks like in a life
What the source says: Ninety degrees apart. Alan Leo treats the square with the opposition and calls it not altogether unfortunate: it holds progress back and makes success indirect rather than obvious, with much depending on the signs involved. One 1918 source reads the same pair of aspects as a bombastic and haughty manner with an inordinate love of display, and someone far too fond of the good things of life and selfish about their own comfort.

Sun trine Jupiter
Sun trine Jupiter brings a kind of quiet confidence that seems baked in from the start — you tend to assume things will work out, and often enough they do. People warm to you without much effort on your part, partly because you make them feel steadied rather than drained. Your generosity with encouragement comes naturally, almost reflexively, and that ease of spirit is something others notice long before you do. The good fortune here is real, even when it looks effortless.
What this looks like in a life
What the source says: A third of the circle apart. Alan Leo calls this the best possible influence of the pair and reads it as assuring a successful career, working in a more material way than the conjunction while carrying everything the conjunction carries. One 1918 source groups the trine with the conjunction and sextile: a sunny and jovial disposition, widely liked, earning it by acts of kindness and by words of sympathy, cheer or hope as the occasion may demand.

Sun opposite Jupiter
Sun opposite Jupiter gives you a personality that fills a room — sometimes by design, sometimes before you've decided to. You want things large: large experiences, large recognition, large proof that your life is going somewhere. The trouble is that the wanting outpaces the timeline, and you can end up projecting confidence that hasn't quite caught up to reality yet. There's also a genuine love of comfort and ease that can tip into self-indulgence before you notice the tipping point.
What this looks like in a life
What the source says: A hundred and eighty degrees apart. Alan Leo treats the opposition with the square and calls it not altogether unfortunate: progress is retarded and success comes indirectly rather than obviously, with the signs involved doing much to shape it. One 1918 source reads the pair as a bombastic, haughty manner with an inordinate love of display, and someone far too fond of the good things of life and selfish in satisfying their own comforts.

Sun and Saturn

Sun conjunct Saturn
Sun conjunct Saturn is the experience of growing up faster than your peers and never fully leaving that behind. You carry expectations — mostly your own — like permanent luggage, and coasting through something feels genuinely foreign to you. There is a quiet pride in doing things properly, a strong internal code of conduct, and a deep discomfort with anything that feels careless or beneath the standard you have set for yourself. Seriousness is not a mood for you; it is closer to a bone.
What this looks like in a life
What the source says: Alan Leo reads this as bringing responsibility into the life, and holds it really fortunate only where the two share a congenial sign. He then divides it by sign class: in the fixed signs a subtle pride or dignity with a keen sense of honour and justice; in the cardinal, intellectual pride and a somewhat cold nature — which he puts down not to a lack of feeling but to a want of breadth of thought.

Sun sextile Saturn
Sun sextile Saturn is the person other people quietly depend on — the one who shows up, follows through, and doesn't require a crisis to stay motivated. You tend to build slowly and keep what you build. Foresight comes naturally to you; so does the willingness to wait out delays that would unravel someone else entirely. Recognition may arrive later than your effort deserves, but the structure you've laid by then is usually still standing when it does.
What this looks like in a life
What the source says: Sixty degrees apart. Alan Leo takes the sextile with the trine here: the whole nature is steadied, the responsibility it brings is not difficult to discharge, and progress upward is slow but held to be sure. One 1918 source groups the two the same way and adds foresight, method and organising ability, with the stamina to carry a project through delays and obstacles — though it holds recognition to be generally late in coming.

Sun square Saturn
Sun square Saturn is the experience of working twice as hard for half the recognition, then wondering whether you miscounted. You plan carefully, move deliberately, and still find the gate has a new lock on it. Praise arrives late if it arrives at all, and you have probably stopped expecting otherwise. What you build tends to last precisely because nothing came easily — but you carry the weight of every delay, every slow start, long after the finish line.
What this looks like in a life
What the source says: Ninety degrees apart. Alan Leo reads this as domestic affliction — limits on progress through the conditions of home, parents and family, and through difficulties the person cannot control. One 1918 source treats the square and the opposition together as adverse to what is generally termed success while abundant in experience: plans thwarted by delay and obstacle, difficulty finding and keeping work, and a sense of being held in leash.
Alan Leo, How to Judge a Nativity (1912; pages from the 1928 printing), p. 134 read itMax Heindel, The Message of the Stars (1918), pp. 262–263 read it
Sun trine Saturn
Sun trine Saturn is the person who finishes what they started, usually without making a fuss about it. You carry responsibility the way others carry a phone — automatically, without noticing the weight until someone points it out. Structure comes naturally, deadlines feel like anchors rather than threats, and you tend to think in longer arcs than the people around you. Recognition often arrives later than it should. That delay rarely stops you, because the work itself already told you it was worth doing.

Sun opposite Saturn
Sun opposite Saturn gives you the sense of arriving just after the door closes — not locked out, exactly, but having to knock twice, wait longer, prove more. You do the work. You put in the hours. And still something slows the return: recognition delayed, effort met with friction, progress measured in small increments rather than clean wins. There is a tired pride in how you carry this, and over time a particular kind of resilience that only the long way round can build.
What this looks like in a life
What the source says: A hundred and eighty degrees apart. Alan Leo calls this pairing very evil, causing obstacles, disappointments and failures, and holding progress back through separations.

Sun and Uranus

Sun conjunct Uranus
Sun conjunct Uranus means you are rarely the same person twice — not because you are inconsistent, but because standing still genuinely feels wrong. You notice the exit before anyone else does, update your thinking faster than your relationships can follow, and resist any structure that feels handed down rather than chosen. The version of you from a few years ago already seems like someone else entirely, and you are mostly fine with that. What you struggle with is being asked to pretend otherwise.
What this looks like in a life
What the source says: No source before the 20th century treats this pair; Uranus was discovered in 1781. One 1918 source groups the conjunction with the square and opposition, and reads them as impulsive and unreliable, with little regard for convention and a strong impatience of any restraint on liberty. Alan Leo notes that no signs had been allotted to Uranus or Neptune, and that for the present they might be taken as substitutes for the Sun and Moon — a hedge worth keeping.

Sun sextile Uranus
Sun sextile Uranus gives you a particular kind of originality — not the loud, attention-seeking kind, but the sort that shows up quietly in how you think and what you choose. You tend to land on solutions other people simply didn't consider. Your independence runs underneath everything, less a statement than a default. You're probably drawn to unconventional interests, comfortable in groups and associations, and generally more interested in what's genuinely new than in what's currently approved.
What this looks like in a life
What the source says: No source before the 20th century treats this pair; Uranus was discovered in 1781. One 1918 source takes the sextile with the trine: original, inventive and independent in conduct and appearance, thought eccentric but not offensively so, drawn to studies people call queer such as occultism and astrology. Alan Leo reads a good aspect here as favouring public appointments and work with societies and associations, and as adding self-reliance.

Sun square Uranus
Sun square Uranus puts you in a permanent, low-grade negotiation with any situation that expects you to simply stay put and comply. You show up, you sense the walls, and something in you immediately starts looking for the exit or the exception. It is not rebellion for its own sake — it is more like a constitutional allergy to being managed. Routines slip, authority grates, and the people closest to you feel the friction first, often before you notice you are pulling away again.

One 1918 source groups the square with the conjunction and opposition: impulsive, unreliable, careless of convention, impatient of restraint. Alan Leo reads a bad aspect as the same Uranian inclination acting erratically — hard on domestic and especially parental harmony, on public position and goodwill, and productive of broken ties.

Sun trine Uranus
Sun trine Uranus gives you an originality that runs so deep you barely notice it yourself. You have never felt much need to conform, but you don't make a performance of that either — the unconventional path just keeps turning out to be the one that fits. You are drawn to ideas and fields that most people find strange or fringe, and you tend to land in groups and circles where individual thinking is the norm. Self-reliance is less a choice than a baseline.

Alan Leo reads a good aspect as fortunate for public appointments and for societies and brotherhoods, and as somewhat increasing the positive side of the nature — self-reliance, independence of character.

Sun opposite Uranus
Sun opposite Uranus puts you in a permanent negotiation between who you are and any structure that tries to define that for you. You agreed to the arrangement, the schedule, the role — and then something in you quietly began undermining it. The pull toward independence is not always chosen; it arrives like a reflex. Routine feels fine until it becomes a rule, and then it becomes the thing you need to escape. Broken ties and reinventions tend to follow.

Sun and Neptune

Sun conjunct Neptune
Sun conjunct Neptune gives you a self that refuses to stay fixed. You walk into a room and quietly become whatever the room needs — absorbing moods, reading silences, sensing the thing no one said aloud. That responsiveness is real and often useful, but it makes the question of who you actually are a surprisingly hard one to answer. Longing tends to run underneath everything: for something just beyond reach, for a life that feels as luminous as the one you sense is possible.

What the source says: No source before the 20th century treats this pair; Neptune was discovered in 1846. One 1918 source groups the conjunction with the square and opposition, and reads them as bringing a person into contact with what it calls the invisible world, while attracting the undesirable element seen at an ordinary seance. Alan Leo notes that no signs had been allotted to Uranus or Neptune, and that for the present they might be taken as substitutes for the Sun and Moon — a hedge worth keeping.

Sun sextile Neptune
Sun Sextile Neptune gives you a finely tuned receiver where most people have an ordinary one. You pick up on the emotional weather of a room before anyone names it, catch the mood shift in a song lyric that others simply hear as background, and sense when someone's reassurance is more performance than truth. That constant low-level intake is not anxiety — it is just how your perception is calibrated. The challenge is learning to trust what arrives before the explanation does.

What the source says: No source before the 20th century treats this pair; Neptune was discovered in 1846. One 1918 source takes the sextile with the trine and reads them as favouring the development of spiritual faculties: an unusual sensitivity to music, and in others a love of the occult approached from the intellectual side, as a psychic investigator rather than a practitioner. Alan Leo notes that no signs had been allotted to Uranus or Neptune, and that for the present they might be taken as substitutes for the Sun and Moon — a hedge worth keeping.

Sun square Neptune
Sun square Neptune leaves you with a self that feels perpetually unfinished — not in a way that troubles you every hour, but in the way a half-remembered song troubles you. You can sense a version of your life that is more vivid, more meaningful, more you, and that nearness makes the actual life feel slightly provisional. You are drawn toward whatever promises transcendence or escape, and you can find it genuinely hard to plant a flag and say: this is who I am, full stop.

One 1918 source groups the square with the conjunction and opposition, and reads them as bringing a person into contact with what it calls the invisible world, while attracting the undesirable element — the sort of thing it says is seen at an ordinary spiritualistic seance. Alan Leo notes that no signs had been allotted to Uranus or Neptune, and that for the present they might be taken as substitutes for the Sun and Moon — a hedge worth keeping.

Sun trine Neptune
Sun Trine Neptune gives you a sensitivity so native to you that it barely registers as a gift. You absorb the emotional temperature of a room before you can name it, slip inside a piece of music before you have chosen to listen, and tend to assume everyone else experiences the world this way too. The pull toward something beyond the ordinary — sound, symbolism, the half-lit edges of things — feels less like a pursuit and more like the air you already breathe.

What the source says: No source before the 20th century treats this pair; Neptune was discovered in 1846. One 1918 source takes the trine with the sextile: a possibility of developing spiritual faculties, an unusual sensitivity to music — it speaks of hearing echoes from what it calls the realm of tone — and in others a love of the occult approached intellectually. Alan Leo notes that no signs had been allotted to Uranus or Neptune, and that for the present they might be taken as substitutes for the Sun and Moon — a hedge worth keeping.

Sun opposite Neptune
Sun opposite Neptune pulls you in two directions at once: toward a vivid, sometimes overwhelming sense of who you could be, and away from any fixed answer about who you actually are. You pick up on atmospheres, moods, and unspoken feeling with unusual accuracy — partly because the boundary between your inner world and everyone else's stays permeable. That porousness is neither flaw nor gift on its own. It is simply the condition you navigate, and navigating it shapes almost everything else.
