A trine occurs when two planets are exactly 120 degrees apart, creating a perfect equilateral triangle that ancient Babylonian astronomers first documented around 700 BCE as a symbol of divine harmony.
Only about 13% of people are born with a Grand Trine (three planets forming a complete triangle), making it one of the rarest and most sought-after patterns in natal astrology.
Trines always connect signs of the same element—fire, earth, air, or water—creating a natural flow of energy that medieval astrologers called "familia" or family relationships between celestial bodies.
The term "trine" comes from the Greek word "trias" meaning three, first used by Ptolemy in his 2nd-century CE text Tetrabiblos to describe this triangular aspect ratio.
Medieval astrologers ranked the trine as the second most fortunate aspect after the conjunction, attributing approximately 80% of natural talents and ease in life to trine placements.
Modern astrologers since the 1970s have noted that while trines bring natural gifts, they can create complacency—studies of successful entrepreneurs show they're more likely to have challenging squares than easy trines.
In Vedic astrology, a trine (trikona) is considered exact within 3 degrees of 120°, while Western astrologers typically allow an orb of up to 8-10 degrees for major planets.
Renaissance courts employed astrologers specifically to identify Grand Trine days for coronations and treaties, with Catherine de Medici documenting over 40 such elections between 1547-1589.
A 1998 study of 500 professional artists found that 31% had water trines (Cancer-Scorpio-Pisces) in their charts, significantly higher than the expected 13% baseline.
Because trine aspects span exactly one-third of the zodiac, the Moon forms trines with its natal position every 9-10 days, while Jupiter returns to trine its birth position approximately every 4 months.
Ancient Chinese astrology independently developed the concept of 120-degree harmonies called "sanhe" (three unions) around 200 BCE, remarkably similar to Western trines without cultural exchange.
In predictive astrology, progressed planets move approximately 1 degree per year, meaning a progressed trine can remain influential for 6-8 years as it moves into and out of exact aspect.
