The alignments of

Jupiter, Saturn, Uranus and Neptune

This page introduces the complex cycles of three giant planets, the patterns of their alignments and provides a timeline of the alignments of Jupiter, Saturn and Uranus from the 15th century to the stellium of 2080, as well as a more detailed timeline of the alignments from the 20th century. See also our pages about the synodic cycles and the stellia of the giant planets and our section about the history of modern artefacts and world history.

The simplest alignment between three or more planets is the stellium, when they gather near the same longitude in the ecliptic within a certain orb, which can vary from a few degrees to 15 degrees or more. In addition to the stellium, a number of additional aspect patterns are possible between three or more planets, based on combinations of two or more major aspects between them.

Major alignments or aspect patterns

The simplest alignments or aspect patterns between three or more giant planets are the following:

  • a Stellium, with the 3 planets aligned around the same longitude on the ecliptic.

  • an Opposition, with 2 planets conjunct each other and making an opposition to the third planet.

  • a Square, with 2 planets conjunct each other and making a square to the third planet.

  • a T-square, with 2 planets in opposition, and the third planet making a square to the other two.

  • a Trine, with 2 planets conjunct each other and making a trine to the third planet.

  • a Grand Trine, with each planet making a trine to the other two, forming an equilateral triangle.

  • a "double sextile", with 2 planets configured by trine, and the third planet at the mid-point, making two sextiles to the first 2 planets. An example of such alignment occurred in October 1957.

The alignments of Jupiter, Saturn and Uranus

We suggest to approach the complex cycles associated with the stellia of three giant planets by starting with the longest synodic cycle they include. The synodic cycle of Saturn and Uranus takes 44 to 47 years and is the longest of the 3 cycles formed by Jupiter, Saturn and Uranus. And Jupiter is the fastest of those 3 planets. Therefore, it makes sense to use Saturn-Uranus alignments as the baseline for Jupiter-Saturn-Uranus alignments. In other words, we can look for Jupiter-Saturn-Uranus alignments during the conjunctions, oppositions, squares, trines or sextiles of the Saturn-Uranus cycle.

When a Jupiter-Saturn or a Jupiter-Uranus alignment occurs during a Saturn-Uranus alignment, then this can be defined as a Jupiter-Saturn-Uranus alignment. Given all the possible combinations of aspects between three planets, those alignments can take a great variety of shapes. Nevertheless, some alignments can be defined as the most basic ones because of the simple geometrical patterns they form.

  • Alignments based on hard aspects: the waxing squares, the oppositions and the waning squares of the Saturn-Uranus cycles occur every 11-13 years, and they last for about 1 year, but sometimes up to 2 years. If, during that timeframe, Jupiter happens to make a hard aspect to Saturn and/or Uranus, then the alignment can form a stellium, a square, an opposition, or a T-square pattern.

  • Alignments based on trines: the trines between Saturn and Uranus occur every 14 to 16 years and last for about 1 to 2 years. If, during that timeframe, Jupiter makes a trine to Saturn and/or Uranus, then this configuration can be defined as a Jupiter-Saturn-Uranus alignment by trine.

Timelines of the alignments of Jupiter, Saturn and Uranus

Timeline of the Oppositions from the 15th century

The timeline of the Jupiter-Saturn-Uranus stellia is available in our page about the stellia of Jupiter, Saturn, Uranus and Neptune. It is remarkable that, during the conjunctions of Saturn and Uranus, Jupiter tends to align with Saturn and Uranus by conjunction or opposition for a few months, forming either a Stellium or an Opposition pattern.

The following timeline highlights the the oppositions of Jupiter to the Saturn-Uranus conjunctions since the 15th century:

  • Jan-Feb 1534: Jupiter oppositions to Saturn and Uranus, after the Saturn-Uranus conjunction of June 1533.

  • Oct 1671: Jupiter oppositions to Saturn and Uranus, after the Saturn-Uranus conjunction of March 1671.

  • Feb 1714: Jupiter oppositions to Saturn and Uranus before the Saturn-Uranus conjunction of October 1714.

  • Oct 1851: Jupiter oppositions to Saturn, Uranus and Pluto during a stellium of Saturn, Uranus and Pluto; and before the Saturn-Uranus conjunction of March 1852.

  • May 1921: Jupiter-Saturn conjunction making an opposition to Uranus, after the Saturn-Uranus opposition of Oct 1918 - June 1920.

  • Aug 1989 - May 1990: after the Saturn-Uranus conjunction of Feb-Oct 1988, Jupiter oppositions to Saturn and Uranus during the stellium of Saturn, Uranus and Neptune of Feb 1988 - Nov 1989 (within 9 to 7 degrees). This series of alignments occurred in the context of the Uranus-Neptune conjunction of 1993.

  • June 2010: Jupiter-Uranus conjunction making an opposition to Saturn at the end of the Saturn-Uranus opposition of Nov 2008 - Jul 2010.

  • Oct 2031: Jupiter opposition to Saturn and Uranus before the Saturn-Uranus conjunction of June 2032.

Combined with the timeline of Jupiter-Saturn-Uranus stellia, the timeline above shows that, during the Saturn-Uranus conjunctions that have occurred since the 15th century, Jupiter has made a conjunction or an opposition to Saturn and Uranus within a few months of the exact conjunction (at most within 11 months in 1921). This suggests that Jupiter should always be taken into account when looking at Saturn-Uranus conjunctions.

We have to go as far as 1398 to find an example where Jupiter did not make a tight conjunction or opposition to the Saturn-Uranus conjunction: in August 1399 Jupiter made a square to Saturn and Uranus, after the Saturn-Uranus conjunction of Apr-Oct 1398. And in January 1404 Saturn and Uranus where within 30 degrees with Jupiter at their midpoint.

Timeline of the Trines and Grand Trines from the 19th century

Here's a preliminary list of Trines and Grand Trines formed by Jupiter, Saturn and Uranus since the 19th century:

  • Oct 1835: Grand Trine during the Saturn-Uranus waning trine of 1835-36.

  • June 1867: Grand Trine after the Saturn-Uranus waxing trine of 1864-66.

  • March 1914: Trine formed by the Jupiter-Uranus conjunction making a trine to Saturn, after the Saturn-Uranus trine of 1912-13.

  • Jul-Aug 1927: Trine formed by the Jupiter-Uranus conjunction making a trine to Saturn, during the Saturn-Uranus trine of 1925-27.

  • Apr-May 1955: Trine formed by the Jupiter-Uranus conjunction making a trine to Saturn, before the Saturn-Uranus trine of 1956-57.

  • Feb 1974: tight Grand Trine after the Saturn-Uranus waning trine of 1972-73.

  • June 2015: Grand Trine before the Saturn-Uranus waning trine of 2016-17, and 180 years after 1835.

  • May 2047: tight Grand Trine during the Saturn-Uranus waxing trine of 2047-48, and 180 years after 1867.

Detailed timeline of Jupiter-Saturn-Uranus alignments from 1900 to 2080

In order to identify all the possible alignments between Jupiter, Saturn and Uranus we need to consider a timeframe of 180 years. We've identified the following alignments, based on conjunctions, oppositions, squares and trines, from the stellium of 1900 to the stellium of 2080:

  • March 1914: Jupiter-Uranus conjunction making a trine to Saturn, after the Saturn-Uranus trine of 1912-13.

  • May 1921: Jupiter applying to its conjunction with Saturn after the 1918-20 Saturn-Uranus opposition

  • Jul-Aug 1927: Jupiter-Uranus conjunction making a trine to Saturn, during the Saturn-Uranus trine of 1925-27.

  • Oct 1957: "double sextile" pattern during the Saturn-Uranus trine of 1957, Jupiter reached the mid-point between Saturn and Uranus, making two exact sextiles to Saturn and Uranus. And Saturn was exactly conjunct the star Antares.

  • June 1965: Jupiter-Saturn-Uranus T-square, with Jupiter squaring the Saturn-Uranus opposition of 1965-67.

  • Feb 1974: Grand Trine of Jupiter, Saturn and Uranus, after the Saturn-Uranus trine of 1972-73.

  • Apr-Sep 1986: Jupiter squares Saturn and Uranus before the 1988 Saturn-Uranus conjunction

  • Sept 1989: Jupiter opposition to Saturn and Uranus after the 1988 Saturn-Uranus conjunction (also including Neptune).

  • May 2000: Jupiter-Saturn conjunction during the Saturn-Uranus waxing square of 1999-2000.

  • June 2010: Jupiter-Uranus conjunction during the 2008-2010 Saturn-Uranus opposition.

  • June 2015: Grand Trine of Jupiter, Saturn and Uranus, before the Saturn-Uranus trine of 2016-17.

  • Oct 2031: Jupiter opposing Saturn and Uranus before the Saturn-Uranus conjunction of 2032.

  • Nov 2041: wide square of Jupiter and Saturn to Uranus, after the 2040 Jupiter-Saturn conjunction and before the 2043 the Saturn-Uranus waxing square.

  • Feb 2045: wide Jupiter-Saturn-Uranus T-square, with Jupiter opposing Uranus after the 2043 the Saturn-Uranus waxing square.

  • May 2047: Grand Trine of Jupiter, Saturn and Uranus, during the Saturn-Uranus trine of 2047-48.

  • Jan 2056: wide Jupiter-Saturn-Uranus T-square, with Jupiter squaring Uranus before the Saturn-Uranus opposition of 2056-57.

  • Aug 2066: Jupiter-Uranus conjunction squaring Saturn at the very beginning of the Saturn-Uranus waning square of 2066-67.

  • Feb 2080: Stellium of Jupiter, Saturn and Uranus (within 5 degrees) after the Saturn-Uranus conjunction of 2079.

A more comprehensive list of Jupiter-Saturn-Uranus alignments, extending beyond the 180-years timeframe, would show how these tend to repeat every 180 years, but it would also show that this pattern is not stable across many centuries. As an example, near 1720, 180 years before the stellium of 1900-1901, one would expect another stellium. But in 1720 there was only a very wide stellium of Jupiter, Saturn and Uranus - within 37 degrees - after the Saturn-Uranus conjunction of 1714. And 180 years earlier, around 1540 there was not even such a stellium. The closest alignment around that time occurred in 1534, with Jupiter making an opposition to Saturn and Uranus after the Saturn-Uranus conjunction of 1533.
