What your charts show

Where to look in both charts.

Same home, different weather

Siblings born a few years apart often have slow planets in common and very different personal planets. That's one way to describe why the same family rules felt fair to one of you and strict to the other.

Mercury and the old arguments

Mercury shows how each of you argues and makes up. Many sibling patterns, like one who wants to talk it out and one who needs to leave the room, are visible here.

Mars and rivalry

Mars describes competitiveness and drive. Two strong Mars placements can mean fierce rivalry and fierce loyalty, often both.

Adult siblings

Comparing charts as adults can be a gentle way to revisit old roles: who was the responsible one, who was the peacemaker, and whether those roles still fit.
