Synastry Notes pt.1
Whole house system
8H Overlay - First of all, this one's hard to maintain unless both people have 8H/Scorpio/Ketu influence in their charts. This is NOT casual. Even small interactions feel charged with subtext and both people know it, it's all about reading between the lines. Usually, the planet person feels an inexplainable pull towards the house person and desire power, even ownership over them. It's the house of joint assets and shared resources so if it's a long term relationship there's inevitably going to be talks of money and they will have joint assets together. Usually it's the house person that benefits from the planet person financially.
If its 8H moon synastry, the moon person becomes invested in the healing of the house person. Regardless of the planets, with 8H synastry they witness crisis filled events in each others' lives, go through ups and downs and stick together throughout all. Mutual obsession, codependency, needing each other like air, triggering each other are all parts of this overlay.
2H Overlay - This overlay brings self worth, assets, finances and family to the forefront. Planet person affects the house person in these areas, so naturally it's usually better to have a benefic planet influencing this house. This overlay makes the couple become very familiar and touchy with one another. They crave each other's presence and physical contact all the time. If it's their Venus/Moon falling in your 2H; your physical appearance and aesthetics probably fit exactly to the house person taste. They find you beautiful, refined and classy, fit for their family. They trust your eye and taste in aesthetics so they may consult your opinion on these matters, as well as ask for your opinion in matters of finances, work and family.
Similar to the 8H overlay, sources and money are highlighted. When their Venus falls in your 2H, you also feel like they’re a source of value, resources, beauty, and even money/comfort. You feel fed by them. Venus doesn’t just sit there, it expresses itself through the area of life it lands in. In your 2H, their Venus energy naturally channels into your possessions, security, finances, and self-worth. They might spoil you, want to provide, beautify your environment or make you feel more secure, which is where it differs from 8H overlays as with 8H fixed stability is hard to catch. But 2H gives safety. Both natives may display similar characteristics/physical features as their partners family.
Also, they definitely find each other's voice extremely attractive.
1H Moon Overlay - Moon person feels exposed in the 1H person’s presence. It’s not just “safe,” it’s inevitable; their emotional state leaks out, even if they normally hide it. They feel like the house person sees straight through them, sometimes uncomfortably. That’s why they can’t keep a poker face here. Their moods, maternal instincts, or emotional baggage show. They may also project their mother issues or care patterns directly onto the house person.
House person feels recognized at a soul level. The Moon person seems to “get” them instinctively, without explanation. The house person often feels comforted, validated, or nurtured, like the Moon person is soothing their very identity. But it can also feel like the Moon person’s moods invade their personal space, because the Moon is right on their “face”
Overall here’s a strong pull of familiarity. It can feel maternal, yes, but also childlike; like both regress around each other. Conversations about family, the past, the mother figure, or emotional security flow naturally.
Upside: nurturing, protective, safe, “I can be myself.” Great for emotional intimacy.
Downside: can be smothering, over-dependent, or too raw. Moon person risks over-identifying with the house person’s identity (trying to mother them), and the house person may feel like they’re carrying the Moon person’s emotional tides on their back.
Also, if house person is someone thats usually unapproachable or intimidating becomes soft and gets more humanized in the presence of moon person. (I read this from notanastrologer and it's very true). That's why people can get surprised about how the house person is so different with the Moon person.
1H Sun Overlay - In contrast to the comfort and fluff of the 1H Moon, this brings authority, visibility and power. If both people have need to be the one in charge, they will clash but if not, house person rides with the tides of the Sun person.
House person feels energized, charged, seen and purposeful in the presence of the Sun person. 1H moon makes the house person feel comforted and seen in an emotional way, but the way Sun makes the 1H person feel seen is like the matter. Sun person here often asserts dominance and authority onto the house person and feel like they have to give "special attention" to them, as well as “be the light” for the house person, which can tip into dominance if unchecked.
House person often admires or looks up to the Sun person, sometimes even mimicking them to “bask” in their glow. But there can also be irritation: “Why do you think you get to define me?”
This is not soft and cozy like the Moon overlay. It’s more about ego recognition and identity ignition. The Sun person pushes the house person into action, visibility, and self-awareness. If the house person has a shaky sense of self, they can feel overshadowed, or like they’re orbiting the Sun. If they’re confident, they can thrive under the Sun person’s attention and even rise to meet it.
10H Mars Overlay - Authority, power, responsibility, purpose and discipline are symbolized by the 10H. Mars is a harsh planet. This couple has potential to ruthlessly go after shared goals & they definitely will have shared goals related to future/goals/money.
Mars here mobilizes the house person and pushes them to work their way up in life. Mars here will definitely feel colder and may be older than the house person. House person can use the Mars person like a social ladder also, while Mars person sees the house person as something to dictate and give orders to. Overall, House person is mobilized, sometimes pressured, to do more and be more. Mars here doesn’t let them coast; it sparks drive and ambition.
Mars person respects the house person’s status/potential, but also want to control or shape it; they see them as “a project” or someone to sharpen.
House person may feel that they find purpose with this relationship.
House person will learn from the Mars person a lot, especially career and their career might even be managed by the Mars person. The house person will admire the Mars person's strength and decision making skills.
Aside from the professional aspects, extremely freaky overlay. Begging, control, authority/submission dynamics, the eroticism of “who’s on top” bleeds from career into bedroom. Might look as a cold or intimidating pair to outsiders.
Sun in 10H = less aggressive, more validating. Sun person is deeply invested in the house person’s public image and career trajectory. They shine a spotlight on the house person and cheerlead them, often obsessing over their success and wanting to bask in it. The house person feels seen and admired for their worldly achievements.
