Understanding Natal Transits

Planetary transits are the ongoing movements of planets through the zodiac as they form angles to the planets in your natal chart. When a transiting planet makes a significant aspect (conjunction, trine, square, opposition, or sextile) to a natal planet, it activates that planet's themes in your life for a specific window of time. Understanding your current transits is the foundation of all predictive astrology.
