Synastry:

How do two people affect each other?

Synastry, also known as relationship astrology, involves the comparison of two astrological charts to determine areas of strength and weakness in a relationship. Synastry is a valuable resource for people who want to examine their relationship with another person based on aspects of each person’s birth charts.

In synastry, the interaction between both birth charts is examined, offering an accurate gauge of compatibility. For instance, a romantic couple might have wonderful Mars aspects and adore outdoor sports that are physically challenging. And on the other hand very difficult aspect between Jupiter and Neptune; this would indicate challenges and difficulties and maintaining a budget.

Composite chart:

What do you and another person create uniquely together?

Take for instance the moon –

The Moon in Composite

In a composite, it is common to assume that the Moon, by sign and house, shows the “comfort zone” of a relationship. It represents the couple’s emotional habits and needs when they are together. We must have all noticed, at one time or another, the way different relationships bring out different emotional reactions in us. When the composite Moon is very strong, it can cause us to seem to change personalities, especially if it is very different from the natal Moon. The baseball and beer fan with the natal Moon in Taurus or Sag may suddenly, in a new relationship, take to the more Libran or Leonine opera and wine. With a new partner, we may suddenly develop new habits, new likes, new dislikes. Old friends may think this is a new false self, but, if it’s genuine, this new horizon is otherwise known as growth within a relationship.
