Trine

Trine is a term used in astrology to describe an angular relationship between two celestial bodies on the zodiac. The word derives from Latin trinus, meaning threefold or triadic. A trine occurs when two planets are roughly 120 degrees apart along the ecliptic, which places them in signs that are three signs apart and typically of the same element (fire with fire, earth with earth, air with air, or water with water).

In practice, the exact degree is approximate and described as an orb. Different traditions give different tolerances, but a common range is about 6–8 degrees for personal planets, with slightly wider orbs for outer planets. Because the signs involved share the same element, the associated energies are thought to flow easily and harmoniously, fostering natural cooperation, ease of expression, and talent that feels intrinsic rather than forced.

In a natal chart, a trine is generally interpreted as a favorable aspect that supports smooth functioning of the involved planetary energies. It can indicate gifts or abilities that come with little effort, as well as a sense of compatibility between the planets’ functions. However, some astrologers caution that easy energy from multiple trines can lead to complacency if not balanced by other aspects.

Grand Trine describes a chart where three planets form trines with each other, creating a large triangular pattern. This is considered a strong but potentially static influence, depending on the overall chart. Trine remains one of the major aspects used to assess harmony and potential in astrological readings.
