Okay, so the other day I was digging into this whole synastry thing, you know, comparing charts to see how people vibe together? And I stumbled upon this aspect, Sun sextile Mars, and I was like, “Hmm, sounds spicy!” So, I decided to put on my amateur astrologer hat and see what it’s all about.

First, I pulled up my own chart and the chart of someone I’m… let’s just say interested in. I use this free online chart calculator, so it’s not super fancy, but hey, it gets the job done. I entered both our birth details—date, time, and place. Boom! Two colorful wheels appeared, full of symbols and lines that looked like some kind of secret code.
Next, I needed to find the Sun and Mars in each chart. The Sun is pretty easy, it’s that big, bright circle. Mars is usually a smaller circle with an arrow pointing up and to the right. I located them in both charts, and then I eyeballed the lines connecting them.
Looking for that Blue Line
See Synastry aspects are all about the Angles, I had learned that the Sextile would mean the Sun and Mars in our charts are around 60 degrees apart. Apparently, the chart calculators usually mark these with blue lines. So, i scanned the inter-chart lines.
- If there’s a blue line, that should mean the Sun in one chart is at 60 degrees angle with the Mars of the other chart.
- The blue lines in online synastry charts usually represent the flowing, and positive aspects.
And there it was! A thin blue line connecting my Sun to his Mars. I felt a little jolt of excitement, like, “Ooh, maybe this is why we have so much fun together!” Then I did some more digging, reading up on what this aspect actually means.
From what I gathered, Sun sextile Mars in synastry is all about energy, enthusiasm, and a bit of a competitive spark. It’s like, you both push each other to be better, to go after what you want, but in a supportive way. It’s not a head-butting kind of competition, more like a playful, “I’ll race you to the top!” kind of thing.
I thought about our interactions, and it kinda clicked. We do have this dynamic where we’re always bouncing ideas off each other, challenging each other’s thoughts, and encouraging each other to try new things. There’s definitely a spark, a sense of excitement and shared drive.
Now, I’m no expert, and I know one aspect doesn’t tell the whole story. But it was a fun little exercise, and it definitely gave me some food for thought. It made me appreciate the energetic connection we have, and I’m curious to see how it plays out. It’s like having a little cosmic thumbs-up, saying, “Hey, there’s something interesting here!”
