Here's a subject I find interesting. How different could twins be if the have different charts?
Since twins are usually born within minutes of each other, their charts are usually so similar that they're almost identical. However, in many cases, twins could have different charts because of different placements of house cusps, especially the Asc. So, while their planetary signs are the same, their house placements could be very different.
I'm one of those. I was born 15 August 1979, 12:30 am (GMT+3), Cairo, Egypt (30n03, 31e15). I have a Gemini Asc. My twin, however, was born around 15 minutes before me, putting her Asc in Taurus.
This is not the only difference in our charts. Our Moons are not very similar. While we both have them in Taurus and in the 12th, her Moon is so close her 1st house cusp that it's technically in the 1st. With such closeness, she have the Moon conjunct her Asc.
Another minor difference is Saturn. Using the Plasidus system Saturn is exactly conjunct my 5th house cusp, while hers is simply in the 5th house without a conjucntion.
There many other differences of course between the charts, but this are the ones that are quite obvious.
I know the differences between my sister and myself. However, I don't know what placements excactly cause those differences. I'd like your opinion on the astrological difference between us. To make things more interesting, I won't share our personality differences right now. I'd like to know what you think of the charts first.
Looking forward to your input.
It's important to distinguish between means and ends.
