Same-Degree Exactness
A partile aspect occurs when two planets are in the same degree of their respective signs for example, Sun at 15° Aries and Moon at 15° Cancer forming a partile square. Partile aspects are the most potent form of any aspect: the two energies are fully engaged, with no approximation. Traditional astrologers considered a partile aspect the most reliable and strongest form of connection between two planets, more significant than a platic aspect within orb but not exact by degree.
Partile vs Platic
| Type | Condition | Strength |
|---|---|---|
| Partile | Same degree number (e.g., 15° to 15°) | Maximum fully active |
| Platic | Within orb but not same degree | Moderate still operative |
A partile conjunction within the same minute (e.g., 15°22' to 15°22') is called a perfect conjunction the absolute peak of aspect intensity.
Using Partile in Chart Reading
When you find a partile aspect in a natal chart especially involving the Sun, Moon, or chart ruler treat it as one of the most important features of the chart. Partile conjunctions in particular are defining natal signatures. In horary astrology, a partile applying aspect between significators is a strong indicator that the matter in question will come to pass. In transits, when a slow planet is partile to a natal planet, the day of partile exactness is typically the most intense expression of that transit's energy.
