Astro synastry observervations 1
Disclaimer: These observation are the niche ways in which a placement may manifest, it is the way I’ve noticed it in others, the people around me, celebrities, myself and in studies. It is not the doctrine wide broad way the placement occurs for everyone.
Chiron conjunct ascendant in synastry can make the Chiron person avoid the Asc person as much as possible, whether it be eye contact or conversation, just being near the ASC person. They also treat the Asc person differently to everyone else, almost like they’re afraid of them or something.
Moon conjunct sun in synastry has beautiful reputation of being felt seen but it also can be negative, it can make the sun person believe they know everything about moon person like how they feel, giving them unwanted advice and thinking they understand the moon person well, all while the moon person feels extremely misunderstood by sun and mis represented and that their advice was useless. Sun person may even try and diagnose moon person because they feel like they have a special ability to know them
3rd house synastry can have you wanting to talk ALLLLL DAYYYY with that person. You can even end up having conversations with them in your head when they’re not even there imagining what they would say or what you could tell them. If mars is here, this is the person you practice how the conversation, debate or argument would have gone in the shower or something
Mars in 6th house overlay can make the house person view the normal basic things that Mars person does to be arousing. For an example if Mars is lightly playing with a stress ball, house person will find the way the ball is being held is really hot and want to be in its place or just find small things like this arousing.
Venus conjunct Jupiter is the most beautiful placement for synastry in my opinion. Venus person has so much love for Jupiter and gives so much everyone can see how much they love Jupiter person, Jupiter’s presence alone can make Venus just sigh in awe. Venus is attracted to Jupiter persons optimism and luck especially concerning themes the house Jupiter lives in. Jupiter person can sometimes not even realise how much they are loved but just know they are appreciated by Venus. This placement to me really does personify pure type of love. These are the people who will do anything for Jupiter and Jupiter just wants to magnify Venus.
Your deepest romantic partners may have your birth city along their Venus line in Astrocartography.
When someone has a sign in Venus it doesn’t strictly mean they’ll only be attrattracted to that sign, but rather it’s the qualities that the sign has in other people
Noticed people who have someone’s Venus in their 8H the planet person can be so respectful to you and make sure that you are well looked after. I really like this dynamic and is my most favorite synastry placements.
Highly saturated 10H stellium in the composite chart can make the both of you unable to communicate to each other without a third party and for your relationship to be the main focus of your image, like you may have had someone else tell your partner that you liked them and that’s how you ended up as a couple, or you may gauge the importance of your relationship not on what you feel or think but- based on what others believe your relationship to be. If people say you two look cute together you will assume all is well between you both but if people say you’re terrible together even if you feel happy you will actually believe what others say your relationship is.
Moon in 5th house overlay will have moon person kicking their feet and giggling like a 13 year old with the house person. They can be the most delightful company to have, can be someone who you spent your childhood with or makes you feel like a child again.
Pluto in 12th house synastry can have Pluto person challenging house persons beliefs to an extent that they’re being disrespectful and forceful. They may degrade the house person for what they believe in, I’ve also noticed that when the Pluto is in sag they can act high and mighty over the 12th house person because sag rules wisdom and higher knowledge, because they’ve done the research they feel like they have the right to critique and degrade 12H belief system and ways of life. 12 house is very sensitive and HIDDEN area so the house person can find their behavior unwanted.
Venus in the 7th house synastry can really have the Venus person giving all they have believing they have found the IT person. ESPECIALLY IF THEIR VENUS IS CONJUNCT PARTNERS MARS. This is because Venus is in its home, native feels safe expressing their love and can feel like they’re meant for this person.
Planets in the 12th house of the synastry chart shows what that person does to you behind your back. For an example Mercury here could indicate the person gossips about you, talks about you when you’re not there. Pluto here can indicate they power-trip or manipulate you without you knowing
Sun- can brag about you, take credit for your work, even say you piggy backed off of them, try to outshine you when you’re not around
Moon- can project their emotions, insecurities on you, feel a lot of emotions about you they dwell on privately, feel dependent on you but don’t show it to you ever, this is like the ex who keeps your clothes long after you break up. Or a friend who plays victim to others and tells their version of the story.
Mercury- analyse and critique you in private, share your secrets with others, discuss opinions about you that they don’t share with you directly
Venus- secretly idealize you, they may secretly have a crush on you, can even want to be you out of envy or admiration, secretly admires you. On the flip side can flirt and seduce you for malicious reasons without you realizing, like in those tv shows where the popular guy dates the weird girl as a dare
Mars- hold back a lot of anger, resentment and bitterness towards you, can be passive aggressive, this is like the Regina George burn book energy.. acting lovely and engaging in person but has so much malice within them you don’t know about, can push or trigger you to anger purposely to get a reaction out of you and you don’t know it
Jupiter- blocks you from getting praise, promotions, blessings, can hold back saying anything nice about you, force their values on you, can deep down feel superior or wiser than you so they subtly guide you to see things their way without being upfront about it, it’s like trying to emigrate into a new country and they bend you to their culture but no matter what you do they’ll never accept you
Saturn- can be very judgmental about you when you’re not there, can act like they literally don’t know you when interacting with others, this is that “I’m embarrassed of them” placement, like a private school student pretending they come from a rich family and ignoring their mother when she comes to pick them up in a Toyota, or a weird anime girl being bullied by her childhood friend because she didn’t want to be affiliated with the weird friends status. it can be very intentional where they try to make things harder for you and ostracize you form others.
Uranus- they literally will rebel against you, this is like a Heian period usurper, except you’re the king. Will challenge you, destabilize you, push you to rebel even, that’s what they do when you’re not around, they push your limits, even putting you into circumstances that you prefer to prepare for, this is like the friend that hosts a surprise birthday party or attempts one of those traumatic YouTube pranks on you like “I CHEATED ON MY WIFE PRANK 4K‼️”
Neptune- project qualities you don’t have onto you, treat you like a person but dehumanize or objectify you when you’re not there, can drug you, can mislead you, keep secrets withholding information to create confusion around their real intentions to you, this one screams situationship or someone who didn’t get access.
Pluto- can try to psychologically manipulate you, deprive and dominate, make you dependent and addicted to them without knowing, can be very envious of you, be possessive
Neptune in person Bs 1st house can make the planet person fetishise the house person, especially if the person B has Neptune in their first house as well, since a Neptune conjunct Neptune synastry makes the planet person fantasise about the best qualities person B has and idealise them.
Mars in 3rd house synastry turns conversations into verbal sparring matches—sharp words, playful teasing, and debates that feel almost like foreplay. The Mars person’s energy can feel invigorating to the house person, but it can also come off as aggressive or argumentative. This placement often leads to mental tension and excitement, with both people constantly challenging each other’s ideas. It’s the kind of connection where you argue for hours, then end up laughing and feeling closer than ever.
Venus square Neptune, Venus person thinks Neptune is everything they’ve been looking for, like their ideal soulmate. They romanticise Neptune to the point of putting them on a pedestal, seeing beauty and perfection where it doesn’t exist. Meanwhile, the Neptune person might not even realize they’re misleading Venus—they’re just existing, but Venus is wrapped up in a fantasy. When the illusion breaks, Venus feels betrayed, like “How could you lie to me?” even though Neptune didn’t promise anything. Neptune might quietly leave Venus wondering, “Did I ever even know them?” There’s a reason why this placement is known as “rose-colored glasses”. I think it’s like when fans meet their favourite artists and they end up being different to the image they portray
Sun in the 6th house overlay can make the Sun person feel like they have a job to fix the house person.The Sun person might try to give the house person advice on everything: their health, routines, work habits, even their diet, like “Have you tried waking up earlier?” or “You’d feel better if you changed this.” The house person might appreciate it at first but eventually feel like the Sun person sees them as a project rather than a person. The Sun person, meanwhile, feels like they’re helping—they don’t realize they might come off as critical. This can also make the house person feel nervous or self-conscious around the Sun, like they’re constantly being evaluated and being around them feels like they’re at work and their neat freak boss is micromanaging.
Venus in the 2nd house overlay makes the Venus person love the house person’s possessions, taste, and even their voice. Venus might compliment the house person’s things endlessly, like “You always dress so well,” or “You have the best taste in music.” There’s something about the house person’s values, style, or even their physical body that Venus finds irresistible. On the flip side, this can make the house person feel like Venus only cares about their surface-level qualities—like they’re being admired for what they have rather than who they are. This can turn into “I feel like you love my things, not me.”
Uranus in the 7th house overlay can feel like falling for someone you never expected to fall for. Uranus person brings an electric energy to the house person that feels exciting but unstable. The house person might feel like they can’t predict Uranus’ next move, which can be thrilling but also nerve-wracking. This is that “I’ve never met anyone like you” dynamic, where both people feel drawn to each other in a way that defies logic. Over time, the house person might feel like Uranus keeps them at arm’s length, refusing to commit or settle down.
Venus Sextile Mars Synastry is one of the sweetest aspects for physical and romantic attraction. Venus is naturally drawn to Mars, thinking “I like the way you move, the way you act—it excites me.” Mars, in return, feels appreciated and energized by Venus’ affection. There’s an effortless rhythm here: Venus brings charm and softness, while Mars adds drive and excitement. They both feel seen and desired without having to try too hard. Unlike harsher Venus-Mars aspects, the sextile creates a playful, flirty dynamic. Mars might tease Venus in a way that makes them blush, and Venus will respond with just enough sweetness to keep Mars coming back. It’s that “You don’t need to chase me; I’m already here” energy. This aspect is natural chemistry without tipping into tension.
When Jupiter lands in someone’s 7th house, the house person feels like Jupiter brings luck, joy, and optimism into their relationships. The Jupiter person can make the house person feel like “Maybe love isn’t so bad after all,” as they bring warmth, generosity, and a sense of expansion to the house person’s idea of partnership. This is the placement where the Jupiter person sees so much potential in the house person, encouraging them to believe in themselves and their relationships. The house person might feel like Jupiter is their good luck charm—like everything is brighter when they’re together. Cons are that Jupiter might unintentionally make promises they can’t keep or come across as “too much” for the house person, overwhelming them with positivity or expectations. This placement often makes the relationship feel like it’s meant to be, as if Jupiter walked into the house person’s life just to show them what a good partnership can feel like.
Venus Square Jupiter screams “You’re too much, but I love it anyway.”This placement can feel like a rollercoaster of indulgence and excess. Venus sees Jupiter as someone greater-than-life, full of warmth and generosity, but also overwhelming at times. Venus might think “Do you really care about me, or are you just like this with everyone?” Whereas Jupiter can feel like Venus is too focused on minor details, like “Why can’t we just have fun without overthinking?” This placement often creates a dynamic where one person loves to give, spend, and shower the other with attention, but the other feels like it’s too much or misplaced. It can also lead to arguments about money or values—like one person wants to splurge, and the other wants to save. Despite the tension, there’s a lot of affection here; the challenge is in finding balance between excess and stability.
Mars in the 7th house makes the Mars person bring a lot of energy—both passionate and combative—into the house person’s relationships. Might find yourself asking why you both argue so much. The house person might feel like Mars is constantly challenging them, either pushing them to grow or picking fights over small things. Mars, meanwhile, feels like they’re just being honest, like “I’m trying to help you stand up for yourself.”This overlay can create a lot of sexual tension, as the house person feels both attracted to and frustrated by Mars’ directness. It’s the kind of dynamic where you argue one minute and make up the next, but if handled poorly, it can feel like constant friction in the relationship.
Mars in the 8th house overlay causes so much tension that never leaves the room, it’s intense and magnetic—the air feels heavier just from being around each other like a glance communicates more than intended, Mars is like the aggressor detective, house is the suspect in question, Mars will do everything to unveil house person but they can’t, it screams Sherlock and Moriarty energy. The house person can’t help but notice Mars, like “Why do I feel like you know all my secrets?” Mars person’s energy triggers something primal in the house person—they might feel exposed and aroused, but also a little uneasy, like Mars sees right through them. Mars, on the other hand, feels like the house person is a mystery they want to unravel. It’s the placement where even small gestures from Mars feel intimate, like brushing against their arm, and the house person thinks, “Do they know how much they’re affecting me?” This connection can lead to intense physical attraction, almost obsessive—where the two can’t stop thinking about each other even when they’re apart. But this is the 8th house, so there’s always the potential for power struggles, jealousy, and intensity that burns out.
Ascendant square mercury creates tension between two people, where Mercury person might say things that unintentionally rub the Ascendant person the wrong way. The Ascendant person might think “Why do they keep misunderstanding me?” while Mercury feels like they’re being perfectly clear. This aspect is common in relationships where you debate or bicker a lot, as Mercury analyzes and questions the Ascendant’s behavior or appearance. The Ascendant person can feel like Mercury doesn’t respect their way of expressing themselves, while Mercury gets frustrated by the Ascendant’s emotional reactions.
For Venus in the 10th House the Venus person brings beauty, charm, and social status to the house person’s public life. The house person might feel like Venus enhances their reputation, thinking “People admire me more when I’m with you.” This placement often creates relationships where one or both partners are seen as a “power couple,” with Venus boosting the house person’s image in career or social settings. On the negative side, the house person might feel like Venus is too focused on appearances, valuing the relationship for what it looks like rather than how it feels.
