The patterns of the

Jupiter, Saturn, Uranus and Neptune cycles

This section explains the patterns of the cycles of the four giant planets Jupiter, Saturn, Uranus and Neptune from an astrological perspective. It includes pages about their synodic cycles, about the stellia they form in the sky, and about their remarkable alignments.

As a whole, the eight planets of the solar system moving around their orbits create a highly complex dynamic phenomenon that challenges human understanding. This complexity can be approached by focusing on the slowest planets - Jupiter, Saturn, Uranus and Neptune - with orbital periods ranging from 12 years to 164 years, and by looking at the simplest visual patterns they form. Those basic patterns through time and space are the following:

  1. The synodic cycles between them: six different synodic cycles are associated to each pair of giant planets;

  2. The stellia when three or more planets gather together in the sky, creating five different stellia;

  3. The alignments or aspect patterns between three or four giant planets, such as T-Squares, Grand Trines, Oppositions or Squares.

This wide spectrum of patterns created by the intertwined movements of the planets around their orbits are the key to understand the astrology of Jupiter, Saturn, Uranus and Neptune.

It's also important to understand other remarkable patterns, such as the periodicity of approximately 179 years for the alignments of Jupiter, Saturn, Uranus and Neptune, and the long cycle between their stellia which has a variable periodicity of approximately 1500 to 2000 years.

The meanings of the six cycles of the giant planets

The following basic meanings can be used as a starting point for understanding the six cycles of the four giant planets.

  • The Uranus-Neptune 171 years cycle sets the rythm of long-term history. Uranus and Neptune are an infinite source of ideas, imagination and dreams that create the future.

  • The Jupiter-Saturn 20 years cycle sets the basic rythm for the organisation of the world. Jupiter-Saturn conjunctions and oppositions coincide with decades and mark the steps for new cycles of reorganisation or restructuring of society, the economy, governments, policies and organisational structures.

  • The shorter Jupiter-Uranus 13.5 years cycle is about formulating and sharing new ideas, while the longer Saturn-Uranus 44.1 years cycle is about materialising those new ideas into tangible objects, such as the bicycle or the computer.

  • The shorter Jupiter-Neptune 12.7 years cycle is about creating and sharing new cultural trends, artistic movements and scientific paradigms that represent humanity's aspirations and dreams, while the longer Saturn-Neptune 36.4 years cycle is about making those dreams real.
