Superior Planet

Definition

A superior planet is one whose orbit around the Sun lies entirely outside Earth's. In traditional Western astrology these are Mars, Jupiter, and Saturn; modern practice adds Uranus, Neptune, and Pluto. Because they orbit beyond us, superior planets can appear at any distance from the Sun in the sky — including opposition, when Earth sits directly between the planet and the Sun. Their retrograde cycles, the stretches when they appear to move backward, are built around that opposition.

In Tradition

In both traditional and modern Western astrology, "superior planet" is a basic astronomical class, defined by orbit, and it shapes how a planet phases and when it is visible. Astrologers agree that a superior planet appears to retrograde because Earth, on its faster inner orbit, overtakes it — a perspective effect — and that this works differently from how the inner planets retrograde. Traditional Western practice further holds that superior planets prefer the oriental phase, rising before the Sun, where they are read as stronger.

In Practice

An astrologer recognizes a superior planet by its orbit: any planet whose average orbital radius is larger than Earth's 1 AU. Its cycle relative to the Sun runs from conjunction (the planet behind the Sun, moving direct), through a first square, the retrograde station, opposition (the planet at its brightest, Earth between it and the Sun), the direct station, and back to conjunction. Each stage is read as a distinct phase in the planet's relationship with the Sun. In traditional electional and natal work, an oriental superior planet — one rising before the Sun — is flagged as a preferred placement, while an occidental superior planet, setting after the Sun, carries a different phase signature.

Historical Origin

The distinction between superior and inferior planets goes back to Ptolemaic astronomy and the geometric model of the Almagest, came down through the medieval Arabic-Latin transmission, and remains the standard astronomical classification in modern Sun-centered astronomy. The astrological reading of phase preferences — oriental versus occidental — is treated by Ptolemy in the Tetrabiblos and elaborated in the Hellenistic technical tradition.

Etymology

Origin: Latin. Meaning: From superior (higher, above) — planets with orbits above (outside) Earth's.
