I got interested in this because I have this with Sun/Venus, Sun/Jupiter, and Moon/Venus. Truth be told it would probably be considered an out-of-sign Stellium. (I'll attach my chart for reference)
I have read the descriptions about about the planets, and how they work together. Personally, I really don't see on an interpersonal level with Sun/Venus. I don't really have a "halo effect" on other people. I'm introverted, and can't take highly social events. It says that Sun Venus people need to be liked, I don't need that I do need people to be genuine and treat me with common courtesy. I do have a huge problem though since it literally in-singes me that I can't control how other people see me. It makes no logical sense because it's literally impossible, but it bugs me none the less; totally irrational. They say there's a dramatic quality to this specific conjunct, but I don't know if it's this or the fact that I have mercury in Leo conjunct midheaven, so take your pick on what makes me dramatic (externally).
This particular conjunction is
Sun at 0°♍/Venus at 29°♌.
Others:
Sun at 0°♍/Jupiter at 22°♌.
Moon at 11°♍/Venus at 29°♌.
Now, everything I read says that I'm supposed to be the hottest thing on two legs. That is not the case, I'm pretty but I'm not magazine pretty or movie pretty. My facial features tend to be large, especially my eyes. Again, other aspects in my chart effect this; I have Uranus in the first house in ♏, it also happens to conjunct my part of Fortune.
The one thing about these conjunctions that I definitely have is high spirituality, high seeking of knowledge, and the need for expansion. I tend to dream a "little" big. I'm a big picture thinker which is weird because half of my Stellium is in ♍. I find the ♌/♍ energy exchange helps me understand my ADHD a lot better.
I do have an effect on people I just don't know what it is, the more I understand about astrology the more I believe that these conjunctions are highly influenced by the fact that I have Chiron in the 7th house. I think it's almost an amplification process.
This seems like a good place to stop. I have a tendency to be information overload. If there is something specific I didn't mention that you want to know feel free to ask.
