Synastry: compare two birth charts
Synastry is the comparison of two people's birth charts by laying one over the other. The aspects one person's planets make to the other person's planets and houses describe the dynamics between the two. For example, if one person's Sun forms a conjunction or trine with the other's Moon, this can describe a natural understanding between them; aspects between Venus and Mars can describe attraction and passion; and aspects between Saturn and the personal planets can describe responsibility, seriousness and at times a sense of restriction. The houses in which one person's planets fall in the other's chart are also interpreted.
Synastry is not a method for predicting whether a relationship will succeed. The charts show where two people get along easily, where effort is needed and how they affect each other. Hard aspects often create attraction, while harmonious aspects bring ease; so a synastry made up only of harmonious aspects and one full of hard aspects can both be interpreted. What really determines the quality of a relationship is the communication and choices of the two people; synastry offers a symbolic reflection of that.
