In astrology, a semi-sextile is a minor aspect formed when two planets or other chart factors are approximately 30 degrees apart. It is commonly associated with subtle connection, adjustment, gradual coordination, and developing awareness between the factors involved. Its influence may be less obvious than that of a major aspect and may become clearer through attention to how the two chart factors interact. Its meaning depends on the planets or points involved, their signs and houses, the size of the orb, and how the aspect fits within the larger chart pattern.
