Planetary Pairs

Timing Important Life Periods With Synodic Returns

Astrology uses two types of planetary motion: sidereal (from sider- the Greek word for star) and synodic (from sunodikós – a Greek word referring to a meeting or assembly). A sidereal return is when a planetary body reaches the same position in the sky relative to a fixed star. A synodic return is relative to a conjunction with its own previous position or a return to a conjunction with another planetary body).
