Okay, so I’ve been diving deep into astrology lately, like really deep. And today, I decided to tackle this “moon square mercury synastry” thing I kept seeing pop up. Honestly, I didn’t even fully grasp what synastry was at first, I just knew I wanted to test it out on some friends to check how accurate it was.
First things first, I needed some birth charts. I used myself and my close friend, because, well, we talk about everything, so I figured it’d be a good test case. I texted them for their birth time (turns out remembering the exact minute you were born isn’t everyone’s top priority, who knew?). Once I had their time, I plugged it all into this this program I like to plot our natal birth charts .
Then I spent like an hour just figuring out how to even read the chart. It took a second, but finally, after a few youtube tutorials, I could pinpoint where the Moon and Mercury were in both of our charts.

Next, I started looking at the aspect between them. I was specifically hunting for that square. A square, from what I learned, means there’s a 90-degree angle between the planets, and it usually indicates some tension or challenge.
The “Aha!” Moment (Maybe?)
After hunting for the square (and many frustrated sighs), I found it! My Moon was indeed squaring their Mercury. My Moon is in Cancer, by the way, which makes me, like, super sensitive and emotional (no surprise there). And their Mercury is in Aries, which supposedly makes them a very direct and, let’s be honest, sometimes blunt communicator.
I started to check out the chart. There were a few things to note, for instance:
- Emotional misunderstandings: Like, I might get all in my feelings about something, and they’ll just be like, “Why are you so upset?” It’s not that they don’t care, it’s just that they process things way more logically, while I’m over here swimming in a sea of emotions.
- Different communication styles: I tend to talk about how I feel, while they’re more focused on facts and solutions. It can be frustrating sometimes, because I just want to be heard, and they just want to fix things.
- Mental vs. Emotional: It’s like my brain is wired to my heart, and theirs is wired to… well, their brain. It’s a classic head-versus-heart kind of situation.
So, yeah, that was my little astrology experiment for the day. It was definitely interesting, and I think it highlighted some of the real-life dynamics in my relationship with my friend. Does it mean we’re doomed? Of course not! But it does give us something to think about, and maybe even work on. I’m thinking of trying this with another friend tomorrow – gotta keep practicing, right? Stay tuned!
