AspectsConjunction (planets are in the same sign) – This aspect brings two like forms of planetary energy together, amplifying the effect on each. The conjunction is the most powerful aspect in synastry and can produce either harmony or disharmony depending on the planets involved. Too many conjunctions between two birth charts can create tension because the people involved are too similar.Trine (planets form a 150deg angle) – This is the most positive aspect in astrology synastry chart. The trine creates compatibility and a harmonious blending. Despite its obvious compatibility, this aspect can cause boredom and repetition. Because these energies are so similar, it is possible for the relationship to lack the passion and urgency that would be associated with other, more challenging aspects.
Sextile (planets make a 60deg angle)-The sextile helps to create a harmonious combination of planetary energies, and a lasting relationship between two people. This aspect is similar in nature to the trine but it can be more stimulating as the signs involved are from different elements. Although this aspect can create a compelling and thrilling response, it can be difficult. It is possible that there will be a strong desire to dominate each other depending on which planets are involved. If there are too many square aspects between two charts, it can lead to an increase in the negative qualities of each person. Opposition (planets formed a 180deg angle): This aspect has a powerful, sometimes destabilizing, effect. These aspects allow the reverse images of identical energy to come into contact. This aspect can be compared to a mirror and creates strong magnetism. Although there is an attraction to this aspect, it can also be challenging. This aspect is stimulating but can cause a competitive spirit to develop between the two parties. This can lead to rivalry and bickering.
Synastry’s Most Important Features
__S.19__ Venus and Mars are particularly attracted to each other. Although Venus’s harsher traits are more likely than Mars’s to foster strong sexual attraction they can also present problems and challenges to the relationship. These planets have a harmonious combination of energies. However, sextile and trine aspects can cause a relationship to feel too familiar and lack excitement. Tensions such as the opposition or square can strain relationships and make it difficult to connect on an intimate basis. Harmonious aspects, such as the trine or sextile, make the interaction easy and comfortable; the partners usually have enough in common to sustain a relationship and are able to form a deep, emotional bond.
