Planetary rulership

Definition
The doctrinal assignment of each zodiac sign to a planetary ruler said to be 'at home' (in its domicile) there. Traditional and modern schemes disagree for three signs and are never silently combined on this platform.
Also called: Domicile · Sign ruler
In more depth
In the traditional scheme, transmitted from the Hellenistic sources through manuals like Lilly's, the Moon rules Cancer and the Sun rules Leo, while the five other classical planets each rule two signs in a symmetrical fan. Rulership underpins much traditional chart judgment: a sign's affairs are read through the condition of its ruler.[1][2][3]
After the discoveries of Uranus, Neptune, and Pluto, much modern Western practice reassigned Aquarius, Pisces, and Scorpio to the new planets. Whether Saturn or Uranus rules Aquarius is a live disagreement between schools: a doctrinal difference, not a question evidence has settled, so any text or tool should state which scheme it uses.[3]
