Sextile
A sextile occurs when two planets sit 60° apart, usually connecting signs of compatible elements (fire with air, earth with water). It's read as an aspect of opportunity — subtler than the trine, requiring initiative to manifest.

Historical fact
Unlike the conjunction, opposition, trine, and square — the four original aspects described by Ptolemy in the Tetrabiblos (c. 150 CE) — the sextile wasn't part of that foundational set and was incorporated into the major-aspect system by later astrologers. Geometrically, it corresponds to a 60° distance, a sixth of the zodiac circle, and typically connects signs of complementary elements (fire-air or earth-water).
Interpretation — Western Astrology (Tropical)
The sextile is read as an aspect of opportunity and potential — gentler and subtler than the trine, but unlike it, doesn't manifest automatically. The traditional reading is that the sextile offers an 'open door' that must be actively walked through: a talent or ease that only converts into real results through the person's conscious effort and initiative.
Interpretation — Vedic Astrology (Sidereal)
A 60° distance doesn't correspond to a standard aspect (drishti) recognized by most planets in the classical Vedic system, which focuses mainly on the 180° opposition and the special aspects of Mars, Jupiter, and Saturn. Because of this, traditional Vedic readings tend to give this specific distance less interpretive weight than modern Western astrology does, reflecting a real structural divergence between the two aspect systems, not just a difference in emphasis.

Frequently asked questions
- What's the difference between sextile and trine?
- Both are read as harmonious aspects, but the trine (120°) is considered easier and more fluid, manifesting almost automatically, while the sextile (60°) is read as an opportunity that needs the person's active initiative to fully materialize.
