♅Uranus
Uranus is a modern planet, discovered in 1781, which contemporary astrology associates with cutting, rupture, and freedom. It takes no part in the traditional system of dignities.
Uranus was discovered in 1781, two millennia after the Hellenistic system took shape. That is why it rules no sign in the tradition and does not enter the calculation of dignities: Efémeris uses it as a sensitive point and for transits, not to judge a planet's strength.
The modern attribution that makes it the ruler of Aquarius displaces Saturn, which is the traditional ruler. They are two different systems, and it is best not to mix them without saying so.
What is attributed to it
Sudden rupture and freedom: what breaks a structure all at once. Modern astrology associates it with the unexpected, with invention, and with rebellion.
Its cycle lasts 84 years—an entire human life. At around 42, at the exact midpoint, Uranus opposes itself: this is the astrological basis of the so-called midlife crisis.
Since it takes seven years per sign, its position by sign is generational, not personal. What individualizes it is its house and its aspects to the personal planets.
Frequently asked questions
Does Uranus rule Aquarius?
In modern astrology it does, but in the Hellenistic tradition Aquarius is ruled by Saturn. Uranus takes no part in the system of dignities, which works only with the seven planets visible to the naked eye.
Why does Uranus not count for the dignities?
Because the system of domiciles and exaltations took shape centuries before its discovery in 1781, and it is built on a geometry of seven planets. Adding an eighth would break its structure.
