The highlighted aspects and patterns which are displayed on these pages are highlighted because they are the primary astrological indicators in the relationships under discussion. Certain aspects of Venus (to the Sun, Venus and Mars) occur more often in relationships. These are the 120 degree trine, the 0 degree conjunction and the 180 degree opposition.
The study which has defined relationship-forming aspects looked at all of the major aspects between Sun, Venus and Mars across couple's natal charts and also progressed charts for the year the relationship began or, in the absence of a relationship start-date, the year of their marriage. The sample used consisted of 1300 public record relationships.
Since this study was completed, data for another 1200 relationships has been collected and not yet analysed in detaill.
