Jennifer Garner’s birth chart, interpreted by The AstroTwins
The following analysis by celebrity astrologers Tali & Ophi Edut, aka The AstroTwins, highlights the most interesting astrological features of Jennifer Garner’s birth chart for all level astrology readers to understand.
When Is Jennifer Garner’s Birthday?
Jennifer Garner’s birthday is April 17, 1972.
Jennifer Garner’s Sun sign is trailblazer Aries
•The Sun represents the essence of your personality, your main character energy•
Jennifer Anne Garner was born at 10 AM on April 17, 1972, in Houston, Texas. Raised in West Virginia and well-known for her TV and movie roles and red carpet poise, she’s always seemed more girl-next-door than diva. Born with the Sun in bold, self-starting Aries, she radiates independence—but with her Sun in her eleventh house of community, she’s a specific brand of star power: the kind that leads with the people, not above them.
The 11th house is astrology’s social hub—connected to friendships, collective vision and the greater good. So while Aries pushes her toward ambition, this house placement makes her shine brightest when she’s championing others. For more than 15 years she’s served as an Artist Ambassador for Save the Children and, in 2017, she co-founded the part-charitable organic baby food company Once Upon a Farm. After the California Wildfires in 2025, she joined World Central Kitchen supporting first responders and residents.
Catapulting to stardom as Sydney Bristow in Alias (for which she won a Golden Globe), Jennifer Garner pours fire sign energy into her roles, like the skilled assassin Elektra in Daredevil and its spin-off Elektra (so Aries!). Thanks to the 11th house placement that emphasizes community and connection, she’s also given us a catalog of “mom’ roles like the family film Yes Day with Jenna Ortega and Love, Simon, in which she plays a supportive mom navigating her son’s coming-out.
The real-life mom of three children exudes PTA-bad-ass-mom energy. She’s an A-list actress who isn’s afraid to roll up her sleeves. In other words, her celebrity isn’t about being in the spotlight, it’s about using it for something bigger than herself.
Jennifer Garner’s natal moon is in a 12th house stellium
•Your moon sign governs the “inner you” and influences your emotions•
If you’ve ever watched a Jennifer Garner be interviewed and thought, how is she this charming?—look no further than her Gemini moon sign. People with this moon sign are clever, curious and endlessly engaging, but it’s not all on display for the Golden Globe actress. Her natal chart moon sits in her twelfth house, alongside Venus, Mars, and Saturn—all in Gemini—creating a quiet powerhouse of thought, feeling and creative depth.
The 12th house is astrology’s backstage lounge. It governs the subconscious, dreams and the parts of ourselves we don’t always show. So while Gemini wants to chat, this placement gives Jennifer a more reflective, even private spin. Even her prolific “Pretend Cooking Show” videos on social media, while welcoming and endearing, have an air of don’t expect me to overshare!
And then there’s her range to consider. Gemini is the sign of duality, after all, and one minute she’s delivering lightning-fast banter in 13 Going on 30 and the next she’s quietly unraveling a character’s inner world in The Adam Project and Dallas Buyers Club. That 12th house influence gives her the emotional intelligence to slip between moods with ease—sometimes without saying a word.
Adding Mars and Saturn to the mix. Mars brings mental restlessness and a need to stay stimulated—cue the nonstop projects, from acting to activism to baking homemade bread or influencing hair care products. Saturn adds an inner discipline; she might come off effortless, but behind the scenes? There’s structure, strategy and probably a deep commitment to doing things “right.” (More on this later.)
With Venus rounding out the Gemini cluster, it’s no wonder she’s so relatable and stylish, yet never flashy. That’s the 12th house in action: hold something back, not out of secrecy, but to protect what matters.

Jennifer Garner’s Saturn in Gemini: Thoughtful charm
•Saturn’s placement in your birthchart can reveal some of life’s toughest lessons•
Behind Jennifer Garner’s easy laugh and breezy charisma lives a much more serious, deliberate thinker—and, as mentioned earlier, that’s her Saturn in Gemini doing the work backstage.
Saturn in Gemini can support “slow builds.” It reflects a deep respect for communication, but often through trial and refinement. In the twelfth house, it’s even more nuanced: this isn’t someone who tosses words around casually. The actress likely grew into her voice, learning when to speak, what to share, and—maybe most importantly—what to keep sacred. Her first on-screen role was as Melissa Gilbert’s daughter in the miniseries Zoya in 1995, a year after graduating Denison College where she changed her chemistry major to theater.
This placement can also reflect a tendency to carry private burdens or to overthink. It’s the “smiling through it” vibe that people sense but can’t quite put their finger on. Think of her enduring grace during public breakups and how she’s handled co-parenting with her ex, actor Ben Affleck. In the spotlight she always appears calm, mature. Saturn here shows up as that quiet composure, even when the pressure is high.
But it’s not all solemn. Gemini’s influence makes her curious, adaptable and mentally agile. Saturn doesn’t stifle that—it sharpens it. Her comedic timing is precise. Her ability to flip from heartfelt to hilarious in a single scene? That’s disciplined duality in motion. And maybe that’s the secret to her staying power: she makes it look effortless.
Love astrology of Jennifer Garner: Flirty but grounded
•Venus and Mars are the love planets in astrology. In your birth chart, Venus represents seduction and romance while Mars represents lust, motivation and erotic instincts.
When Venus and Mars meet in a birth chart, it signals someone who blends charm and desire. Add Gemini to the mix—and lock them into an exact conjunction—and you get Jennifer Garner: the sparkling conversationalist, the flirty-but-grounded rom-com queen, and someone who genuinely connects.
Venus in Gemini is curious and light on its feet. Mars in Gemini is restless, witty and sharp. Together, these two give her a natural spark with others—especially those who can keep up mentally. She’s not swept away by grand gestures but rather drawn to playful banter, late-night talks and relationships that keep evolving. In other words: chemistry built on connection, not control.
In real life, that showed up in her highly public marriage to Ben Affleck. On paper, they were a classic Hollywood match—power couple status, a beautiful family, years of shared history. But this Venus-Mars in Gemini placement suggests Jennifer needs variety, communication and emotional flexibility in her closest bonds. Gemini energy also doesn’t like feeling stuck or silenced. Over time, those dynamics may have quietly eroded their connection—even if the love and respect remained.
What’s striking, though, is how gracefully she navigated the aftermath. That 12th house placement means her romantic life isn’t something she parades around. Even during very public moments—like Affleck’s second, high-profile marriage to Jennifer Lopez—she’s has stayed composed, prioritizing her role as a mom and keeping her own romantic relationships private (like her one with John Miller, CEO of West Coast restaurant chain, CaliBurger, which whom she’s dated for more than five years).
Jennifer Garner’s Cancer Rising: Real-deal nurturing
•Your rising sign, or ascendant, is the first impression you make. Like a filter, it “tints” your Sun sign•
Jennifer Garner is a Cancer Rising. People with this placement often come across as nurturing, but not in a performative way. It’s the real deal. You feel safe around them. You want them on your team, whether you’re going through a breakup or just need a snack.
It’s also what gives the mom and actress that relatable but still luminous vibe. Cancer risings don’t seek attention—they draw it in by being emotionally present, by feeling like someone you’ve known forever. Combine that with her Aries Sun and Gemini stellium, and you get someone who can switch from action-hero to apron in an instant, and somehow make both feel completely natural!
Cancer is also ruled by the moon, and with her moon in Gemini (in the deeply private twelfth house), she may come across as open but her emotional world is more complex. There’s a self-protective streak here, one that helps her maintain a boundary between public and private life.
And let’s not forget—Cancer is the sign of motherhood. Her rising sign underscores what so many fans admire about her: the way she holds family close and leads with empathy. Whether she’s playing a doting mom on screen or showing up as one IRL for her three children, it’s not a role—it’s her essence.
Jennifer Garner’s Jupiter: The graceful grown-up in the room
•Jupiter in your birth chart reveals where you’re adventurous and willing to take risks•
Jennifer Garner’s chart isn’t just wired for charm. Her Jupiter sits in Capricorn in the seventh house of marriage and partnerships, spotlighting her deep respect for loyalty and shared growth in relationships.
Jupiter is the planet of expansion, and in the 7th house, it often indicates someone who learns and evolves through their closest one-on-one connections. With Capricorn here, she’s not playing games—she’s in it for the long haul. Love, for her, isn’t just about chemistry or compatibility. It’s about showing up. Building something real. Weathering life together.
That might explain why her marriage to Ben Affleck had such endurance, even amid the demands of fame. Capricorn doesn’t do impulsive; it’s patient, pragmatic and quietly determined. And even though their relationship eventually ended, she’s continued to model what mature love—and even post-love—can look like, as well as co-parenting.
Jupiter here also gives her a natural generosity in partnership. But Capricorn adds a high bar—she’ll go all in, but only if the foundation is strong. That could be why her current relationship with John Miller has been largely under the radar and why she has said in interviews that she’s not ready to get married again.
North Node in Aquarius: From star to steward
•Astrologers use the nodes of the moon (found opposite each other in your birth chart) to determine where your destiny lies (North node) and what you were in past lifetimes (South node).
The North Node is the soul’s compass pointing toward growth, purpose and the work we’re here to do in this lifetime. For Jennifer Garner, that North Node sits in visionary Aquarius, a sign that calls her to action.
Aquarius is the sign of the collective. It’s about community, innovation and carving out new ways of being—especially when they challenge the status quo. With this placement, Jennifer’s path isn’t just about personal success (though she’s had plenty of that!); it’s about using her voice, her platform and her influence to lift others.
And she’s doing just that: from her advocacy work with Save the Children to her co-founding the baby food company aimed at helping families access nutrition. She’s embodying her North Node by stepping into roles that impact the greater good. It’s not performative—it’s purpose-driven.
This placement also asks her to let go of old patterns tied to the Leo South Node. While Leo craves applause and personal recognition, Aquarius pushes her to share the stage.
In her career, this might mean choosing roles or projects that have a message—ones that reflect progress, heart and inclusivity. In life, it shows up as that blend of star power and soulfulness: the ability to be admired, yes, but also deeply trusted.
