Orbit

Definition

An orbit is the curved path one celestial body follows around another because of gravity and motion. Earth orbits the Sun, while the Moon orbits Earth. Astrology usually depicts planetary positions from a geocentric viewpoint, so a planet’s displayed movement through the zodiac is its apparent path as seen from Earth rather than a literal orbit around Earth.

Astrological Meaning

Orbital cycles provide the astronomical timing behind planetary returns, transits, retrograde appearances, and changing zodiacal positions. Faster bodies, such as the Moon and Mercury, complete their cycles relatively quickly and are often associated with shorter-term developments. Slower planets take years or decades to move through the zodiac, giving their transits a broader collective or generational context. Traditional and modern astrologers use ephemerides or software based on orbital calculations to determine accurate planetary positions.

Why It Matters

Understanding orbit helps separate astronomy from symbolic interpretation. It explains why planets move at different speeds, why retrogrades are apparent from Earth, and why planetary cycles repeat at recognizable intervals. It also prevents confusion between orbit and orb: an orbit is a celestial path, while an orb is the permitted range of degrees around an astrological aspect. This distinction supports clearer chart interpretation and more accurate use of astrological terminology.
