She talks softly to the cat. She does not perform fear—she performs procedure, and the fear leaks through. Sigourney Weaver's Libra Sun, Taurus Rising chart explains why Pluto squaring her Moon in 2026 is the transit that matters.

In the third act of Ridley Scott's Alien (1979), warrant officer Ellen Ripley is alone on the shuttle, stripped down to a tank top, and the actress playing her does something almost no one else would have done in 1979: she keeps the camera waiting. She talks softly to the cat. She buckles in slowly. She does not perform fear. She performs procedure, and the fear leaks through the procedure. That stillness — the refusal to oversell — is the through-line of a fifty-year career.
<a href="https://en.wikipedia.org/wiki/Sigourney_Weaver">Sigourney Weaver</a> was born Susan Alexandra Weaver on October 8, 1949, at 6:15 in the evening in Manhattan, the daughter of NBC president Pat Weaver and English stage actress Elizabeth Inglis. She renamed herself at fourteen, lifting "Sigourney" from a minor character in The Great Gatsby. The chart cast for that birth moment is one of the most internally consistent celebrity charts in film, and also one of the most quietly contradictory. It promises diplomacy and delivers, instead, a woman willing to be unlikable on screen for the sake of the truth of a scene.
Her birth time is rated AA on the <a href="https://www.astro.com/astro-databank/Weaver,_Sigourney">Astro-Databank</a> Rodden scale — sourced from the birth certificate — which means the rising sign, the angles, and the house placements below are reliable, not estimated. That matters because the most interesting thing about this chart sits exactly on the angle.

FAQ
What is Sigourney Weaver's birth chart?
Sigourney Weaver was born October 8, 1949, at 6:15 PM in Manhattan. She has Sun in Libra at 15°19' (6th house), Moon in Taurus at 5°19' (12th house), and Taurus rising at 6°29'. Her Moon sits within roughly one degree of her Ascendant — a defining placement. The birth time is Rodden-rated AA.
Why does Sigourney Weaver's Sun-Neptune conjunction matter?
Her Sun and Neptune are conjunct in Libra at only 0.4 degrees of orb — the tightest aspect in her chart. Neptune dissolves whatever it touches; conjunct the Sun in the sixth house of work, it fuels the unusual capacity to vanish into roles like Ripley while leaving the actor uncertain of who she is between projects.
What current transits are affecting Sigourney Weaver in 2026?
Pluto in Aquarius is squaring her natal Taurus Moon and Ascendant by less than one degree of orb through 2026, with passes continuing into 2027. Saturn in Aries is also building toward an exact opposition to her Sun-Neptune conjunction in late 2026 and early 2027 — the second time she has lived through that aspect.
What does Mars conjunct Pluto in Leo mean in her chart?
Mars at 19° Leo sits within 1.69 degrees of Pluto at 17° Leo, both in her fifth house of creative expression. This combination produces controlled, theatrical, almost surgical force — the chart signature behind Ellen Ripley and her willingness to play characters whose strength reads as physical inevitability rather than performance.
Is Sigourney Weaver's birth time verified?
Yes. Astro-Databank rates her birth time AA on the Rodden scale, meaning it was sourced directly from the birth certificate. This makes her rising sign, house placements, Midheaven, and time-dependent aspects reliable rather than estimated. It is the highest standard of birth-data verification in astrology.
Weaver's Sun sits at 15°19' of Libra in the sixth house, the house of work, craft, and daily discipline. The Sun in Libra — the cardinal air sign symbolized by the scales — is conventionally read as the diplomat, the partner-seeker, the person who needs the room balanced before they can think. You can see it in her press persona: the long pauses before she answers a question, the visible weighing, the courtesy that never tips into sycophancy. In her 1989 Golden Globes acceptance speech — when she won twice in one night, for Gorillas in the Mist and Working Girl — she thanked her co-stars in a way that felt rehearsed in the right way. She had thought about who deserved naming.
But Libra in the sixth is not the salon Libra. It's the workshop Libra. The sixth house grinds. Combined with the Sun-Neptune conjunction sitting on top of it (more on that in a moment), the placement asks her to find harmony through service to the work itself, not through being liked. The cost is a chronic tendency to disappear into a role's discipline — long preparation, weight loss, stunt training for Aliens — and to mistrust her own fame as a vulgarity. The complication: the cardinal air sign that wants to lead through agreement is sharing a room with Mars-Pluto in Leo a few houses over, which does not want to agree with anyone. That tension is the real engine.
Moon in Taurus, Conjunct the Ascendant from the 12th House
Her Moon at 5°19' of Taurus sits within roughly one degree of her rising sign — close enough that her emotional life and her embodied public face are almost the same instrument. Taurus is the fixed earth sign of the body, of voice, of slow weight. In a Moon-on-the-Ascendant person, you usually feel the mood before you hear the words; with Weaver, what you feel is gravity. The 6'0" frame helps, but it isn't the height. It's that the Moon-Taurus pulls every gesture half a beat slower than the scene around her. Watch her in the boardroom scene of Working Girl — Katharine Parker doesn't move fast, she moves heavy.
The catch is the house. Her Moon technically lives in the twelfth, the house of solitude, hidden things, and what is screened from view, before crossing the Ascendant into visibility. That creates a private interior the public never quite reaches; she has spoken in interviews about being "shy" despite four decades on screen, and the placement matches. The cost is loneliness-in-presence: the Moon-12th can read every room and still feel, at the end of the night, like the only person in it. The complication: with Pluto in Aquarius currently squaring this Moon by exact degree (more on that in the transits section), the 12th-house Taurus calm is being asked to renegotiate what it means by "safety."
Taurus Rising
The Ascendant at 6°29' of Taurus is the keystone. Taurus rising shows up in the body as an unrushed center of gravity — the famous Weaver stillness that directors from Ridley Scott to James Cameron to Roman Polanski have all shot in close-up, knowing she will not flinch under the lens. Ruled by Venus in Scorpio (we'll get to her), the rising sign also explains why she has aged on-screen with so little visible defensiveness; Taurus rising tends to accept the body's verdict.
The trade-off is rigidity. Taurus rising can be slow to pivot — slow to change agents, slow to leave a project, slow to reinvent. Her career has had long stretches between the peaks (the gap between Death and the Maiden in 1994 and her Avatar renaissance in 2009 was real), and Taurus rising is part of the answer: she will outwait an industry rather than chase it. The cross-placement complication is Mercury square Uranus by 0.26° of orb — a wiring that wants sudden, sharp, surprising language. The body is patient. The mind is not.
Personal Planets: Mercury, Venus, Mars
Mercury Retrograde in Libra in the 6th, Square Uranus
Mercury at 5°16' of Libra, retrograde, in the sixth house, with a near-exact square to Uranus in Cancer — this is the writer's mind, not the talk-show mind. Retrograde Mercury thinks before it speaks and edits after it speaks, which is why her interviews tend to circle back: "let me put that better." The Libra placement gives her diplomatic phrasing; the sixth-house grounding makes her language work-specific, not abstract; the Uranus square keeps a sudden, almost rude, intelligence on tap. You can watch the Uranus square fire in the 60 Minutes appearances and in her Yale-trained command of Shakespeare — it's the part of her that won't soften the punchline.
The cost: Mercury Rx in Libra can second-guess a yes for years. She has spoken about hesitating to commit to roles, about the slow internal weighing.
Venus in Scorpio in the 7th House
Venus at 28°19' of Scorpio sits in the seventh house, the house of marriage and chosen partnership, at the very last degree before crossing into Sagittarius — what astrologers call the anaretic degree, the degree of urgency. Venus in Scorpio loves the way a Scorpio loves: privately, intensely, and without performance. She married theater director Jim Simpson, founder of New York's Flea Theater, in 1984, and has stayed married to him; the union has produced one daughter, Charlotte, born in 1990. Venus in the 7th does want partnership; Venus in Scorpio just doesn't want to talk about it.
The trade-off is that this Venus does not do casual. The seventh-house Scorpio Venus can read betrayal where there is none, and can hold a grudge as a kind of devotion. In her on-screen relationships, she has consistently been cast as the woman who loves intensely or coldly but rarely warmly — the icy executive of Working Girl, the haunted survivor of Death and the Maiden. Casting directors read the chart whether they know it or not.
Mars Conjunct Pluto in Leo, in the 5th House
This is the placement that explains Ripley. Mars at 19°28' of Leo, sitting within 1.69° of Pluto at 17°47' of Leo, in the fifth house of creative self-expression. Mars-Pluto is the chart signature of someone who can summon an enormous, controlled, almost surgical aggression — the willingness to flamethrower a Xenomorph queen and mean it. Add the Leo placement and the fifth house, and the aggression becomes performative in the best sense: stylized, owned, theatrical. She doesn't act tough; she lets you see the calculation behind the toughness.
The cost is that Mars-Pluto people can intimidate at rest. She has joked in interviews that she frightens directors before they meet her. The Leo fifth house also means her creative drive runs hot, and the Libra Sun's diplomacy is the only thing keeping the politics survivable — without the Libra cooling system, this Mars-Pluto would scorch every set.
Where the Chart Pushes Back
This is the section where the chart stops being a flattering portrait.
<strong>Sun conjunct Neptune at 0.4° of orb.</strong> This is the tightest single aspect in the entire chart, and it is not, by any honest reading, an easy gift. Neptune dissolves whatever it touches; conjunct the Sun, it dissolves the sense of a fixed self. Compare it to the Sun-Neptune conjunctions in other actors of her generation, and the pattern repeats: people who are extraordinary at vanishing into roles and chronically uncertain about who they are when the role ends. She has described the post-shoot crash, the months of disorientation after long projects. The flip side of being able to <em>be</em> Ripley for forty years is not always knowing where Ripley ends and Susan begins. The Libra Sun-Neptune in the sixth house gets a glamour glow on screen and a fog at home.
<strong>Mercury square Uranus at 0.26°.</strong> This is the second-tightest aspect. The square is the friction angle: the mind wants to be sudden, electrical, contrarian, and the rest of the chart (Libra-Taurus, slow and pleasing) does not. The result is a person who is genuinely capable of saying the wrong thing on purpose — the Cannes Film Festival press conferences where she has cut off interviewers, the bluntness about Hollywood ageism. The cost is interpersonal cost. People with Mercury square Uranus burn bridges they did not mean to burn, and Mercury Rx means they replay the burning at 3 a.m.
<strong>Saturn in Virgo in the 5th, square nothing major but quietly heavy.</strong> Her Saturn at 14°02' of Virgo also lives in the fifth house, the house of creative play — and Saturn in the fifth is famously the placement of the artist who works rather than plays. It explains the Yale School of Drama MFA, the textual rigor, the refusal to phone in a comedy. The cost is that play does not come easily. She has had to choose her comedies (and her Ghostbusters (1984) Dana Barrett is funnier <em>because</em> the Saturn discipline is visible underneath the chaos), and the chart explains why even her lightest work has a slight gravity she cannot shed.
Notable Aspects
Moon sextile Uranus (orb 0.3°) — the emotional life is wired for sudden insight; explains the speed of her instinct on a take. Sextiles flow, but they also require active use, and in her case the Moon-Uranus has been the source of the unexpected line readings that make her performances unmistakable.
Mars conjunct Pluto, both sextile her Sun (orbs 4.15° and 2.46°) — a power configuration that lets the Libra Sun draw on Leo Mars-Pluto force without being overwhelmed by it. This is a leadership wiring, but a costly one: the Sun has to keep authorizing the Mars-Pluto to act, which takes ongoing inner work.
Jupiter conjunct the MC at 2.62° orb — Jupiter on the Midheaven is the classic 'publicly successful' signature. Her career is genuinely, structurally fortunate; the chart is honest about it. The complicating note: Jupiter in Capricorn is Jupiter in its detriment, where expansion is asked to come through restraint and earned authority rather than charisma. She has had to work for the size of her career, not coast on it.
Saturn trine Ascendant (orb 7.55°) and Uranus sextile Ascendant (orb 1.47°) — the body holds both discipline (Saturn) and the capacity for sudden, electrifying presence (Uranus). The combination is rare; it is part of why she reads as both timeless and live-wire on camera.
Career and Public Life
The chart promised her this career, and then quietly demanded that she earn every inch of it. Jupiter conjunct the MC in Capricorn is the public-success signature; Saturn in the fifth is the work-don't-play signature; the Sun-Neptune in the sixth is the disappear-into-the-craft signature. Together they describe almost exactly what happened: Stanford BA in English in 1972, Yale MFA in 1974, two years of off-Broadway and rejection, and then Alien at age twenty-nine — late by ingenue standards, exactly on time by Jupiter-MC ones.
The tension between chart promise and lived career sits in the eight-year stretch from roughly 1995 to 2009, when leading roles thinned and the industry struggled to cast a six-foot-tall Libra in her forties as a romantic lead. The chart wanted prestige and got, instead, a long Saturn-in-Virgo apprenticeship — supporting roles, voice work, Galaxy Quest (1999), The Ice Storm (1997). Then James Cameron called for Avatar, and Jupiter-on-the-MC paid out again, twice — first as Dr. Grace Augustine in 2009, then as the Na'vi adolescent Kiri in Avatar: The Way of Water (2022), a piece of casting that asked a seventy-three-year-old to play fourteen and made it work.
For chart-pattern comparison, look at fellow Libra Suns <a href="/celebrities/tessa-thompson">Tessa Thompson</a> and <a href="/celebrities/matt-damon">Matt Damon</a> — both share the Libra need to balance an industry that does not balance back, but neither has the Mars-Pluto in Leo to weaponize the polite voice the way Weaver does. The closer Taurus-anchored comparison is <a href="/celebrities/cate-blanchett">Cate Blanchett</a>, whose Taurus Sun gives her a similar gravitational stillness on screen; Weaver gets to that stillness via Taurus <em>rising</em>, which means she earned it physically rather than inheriting it from her solar identity.
The double Oscar nomination of 1988 — Best Actress for Gorillas in the Mist and Best Supporting Actress for Working Girl — is the Jupiter-MC moment of the chart. She did not win either. Mars-Pluto in Leo took it personally. She has been honest, in interviews since, about the sting.
Relationships
Venus in Scorpio in the 7th house, with the Descendant at 6°29' of Scorpio — a partnership signature that wants intensity, privacy, and longevity in roughly that order. She married Jim Simpson, founder of New York's Flea Theater, in October 1984; their daughter Charlotte was born in 1990. The marriage has been notably out of the tabloid cycle — which is the seventh-house Scorpio working as designed: the partnership is real, and it is not for public consumption.
Mars in Leo in the 5th sextiles the 7th-house Venus but does not aspect it directly, suggesting a partnership in which her creative life and her romantic life have been deliberately kept on separate circuits. The 5th house holds the daughter, the play, the theater work; the 7th holds the marriage. A useful contrast is the Libra Sun-Scorpio Venus combination of <a href="/blog/sharon-osbourne-birth-chart-libra-astrology-2026">Sharon Osbourne</a>, whose chart took the same emotional hardware in a much more public direction. Same wiring, opposite use.
The Transit That Actually Matters
<a href="/blog/saturn-sextile-pluto-aries-aquarius-march-2026">Pluto in Aquarius is currently at 5°29' of the sign, applying to an exact square</a> of her natal Taurus Moon at 5°19' and her Taurus Ascendant at 6°29'. The orb on the Moon is under one degree right now, in late April 2026, and tightens through the summer before Pluto retrogrades back over the same ground in autumn 2026 and again in 2027. This is the aspect of the chart in 2026.
What it means in plain language: Pluto's job is to compost. It finds the structure you have built your sense of safety on — and for Weaver, the Taurus Moon-on-the-Ascendant is exactly that structure, the famously unflappable physical and emotional steadiness that has carried her career — and it asks whether the structure is still alive or just habit. Pluto squares are not catastrophes; they are excavations. They tend to manifest as quiet but irreversible reorganizations: the role she would have taken at sixty that she will not take at seventy-six, the public posture she has held for forty years that she may simply put down. Because the transit hits the Ascendant simultaneously, the body itself is part of the renegotiation — the way she shows up in a room is being remade.
The supporting transit is Saturn in Aries at roughly 8°37', applying to oppose her Sun-Neptune conjunction in Libra (15°-15°) by exact aspect later in 2026 and into early 2027. Saturn opposite Sun is the maturity-reckoning transit; she has lived through it once before, in 1995-96, when her career thinned. This second pass is the elder version: not the loss of the role, but the reckoning with what the roles cost. Combined with the Aliens 40th-anniversary cycle landing in the same year, the symbolism almost over-rhymes.
What This Chart Asks You to Reckon With
The flattering reading of Sigourney Weaver's chart is that she is a Libra-Taurus diplomat-monument with a useful streak of Leo fire — graceful, grounded, formidable. The harder reading, and the one the chart actually supports, is that she is a person whose Sun-Neptune conjunction has spent fifty years dissolving into other women, whose Mars-Pluto can intimidate without trying, whose Mercury-Uranus has cost her relationships she would have wanted to keep, and whose Taurus rising is now being asked, by Pluto, to let go of the very steadiness that became her trademark.
The contrarian observation is this: the cultural narrative about her is that she was a "feminist icon" who broke the action-hero ceiling. The chart suggests she is something stranger and more interesting — a deeply private 12th-house Moon person who got cast as the public face of female strength almost by accident, because Ridley Scott needed a tall woman who could stand still. She has spent the rest of her career renegotiating that accident with the dignity of her Jupiter-on-the-MC and the stubbornness of her Taurus rising. The Pluto transit now is asking whether she is willing, at seventy-six, to be something other than the woman who survived the Xenomorph. The chart's honest answer is: probably yes, and quietly.
