Okay, so I’ve been diving deep into astrology lately, and composite charts have totally caught my attention. It’s like, instead of just looking at individual birth charts, you blend two people’s charts together to see the energy of the relationship itself. Wild, right?

Today, I decided to tackle a specific aspect in a composite chart: Sun square Jupiter. I’d heard this one can be a bit tricky, so I was curious to see it in action. I grabbed the charts of, um, two very close friends of mine (who shall remain nameless for privacy’s sake, of course!). I’ve watched their relationship go through some serious ups and downs, so I figured they’d be a good case study.
First, I pulled up their individual birth charts online. You just need their birth dates, times, and locations. There are tons of free websites that will do this for you.
Then, I used another website that specifically creates composite charts. It basically takes the midpoints of all the planets and angles in the two individual charts. Again, super easy to find one of these online.
I loaded in the birth data, and boom – there was the composite chart. I scrolled down to the aspect list, looking for that Sun-Jupiter square. And yep, there it was, clear as day.
Getting into the Details
So, what did I actually see? Well, I already knew these two have some big personality clashes. One is super optimistic and always wants to go big (classic Jupiter!), while the other is a bit more grounded and focused on their own individual goals (Sun!).
The square aspect, in general, represents tension and challenges. It’s like two forces constantly pushing against each other. So, a Sun square Jupiter in a composite chart? It can manifest in a few ways, from what I’ve read, and from what I see with my friends, and I began to noticed.
- Overspending/Overdoing: They are constantly going on extravagant trips or buying things they don’t really need. It’s like they’re trying to one-up each other, or maybe fill some kind of void.
- Clashing Beliefs: One is super into, like, new-age spirituality, while the other is a hardcore, down-to-earth, show me proof,science type. It leads to some heated debates, let me tell you.
- Ego Battles: It’s like they’re both competing for the spotlight. There’s this constant struggle for who’s “right” or who’s the “leader” in the relationship.
I spent a good couple of hours just reading up on different interpretations of this aspect, and cross-referencing it with what I knew about my friends’ relationship. It was actually kind of eerie how much it resonated.
I even jotted down some notes, comparing the composite chart to their individual charts. I wanted to see if there were any other aspects that were either amplifying or softening this Sun-Jupiter tension. It’s like putting together a puzzle, you know?
The Takeaway
Honestly, doing this little exercise made me realize how powerful composite charts can be. It’s not about predicting the future or anything, but it gives you this really interesting insight into the dynamics of a relationship. It highlights the potential challenges, but also the potential for growth.
It made me have deeper and meaningful conversations with my two friends, without going into detail of course.

For my friends, I think understanding this Sun-Jupiter square is a step towards navigating their differences more consciously. Maybe they’ll realize they don’t always have to go so big, or that it’s okay to have different beliefs. It’s all about finding that balance, right?
I’m definitely going to keep exploring composite charts. It’s like a whole new level of astrological understanding, and it’s pretty addictive, not gonna lie!
