In astrology, a trine is a major aspect formed when two planets or other chart factors are approximately 120 degrees apart. It is traditionally associated with ease, harmony, natural expression, and supportive interaction between the factors involved. In a natal chart, a trine may point to qualities, abilities, or patterns that operate with relatively little friction. 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.
