What sets Composite Chart apart

A composite takes each planet in the two charts and places a new planet at the midpoint of the two, on the shorter arc, so the Sun at 10 Aries and a Sun at 20 Gemini give a composite Sun at 15 Taurus. The result is a single chart with no real birth moment: it describes the pair as one thing. Where the two are more than 180 degrees apart the nearer midpoint is chosen, which is the opposite point from the plain average.

Often mistaken for something else: The composite is one chart of midpoints. Synastry keeps two charts, and a Davison chart uses a real midpoint in time and place instead of averaging each planet.
