Ruling planet
From Biocrawler, the free encyclopedia.
In astrology, a ruling planet is a planet of the solar system that is associated more strongly with a particular sign of the Zodiac than other planets are thought to be. The ruling planet for a given sign affects that sign even when the ruling planet is not in the sign or in an astrological aspect related to the sign.
The assignments of the ruling planets appear to be based upon the Northern Hemisphere seasons, as the Sun (Sol) and the Moon, the principal bearers of light and heat, were awarded to Leo and Cancer, respectively, since the months the sun passed through these signs (in ancient times) were the warmest and had the longest days.
Conversely, Saturn, the most distant (and hence the "coldest") of the planets known to ancients, was accorded the rulership of Aquarius and Capricorn, the signs opposite Leo and Cancer, respectively.
Jupiter, being next furthest away, was given the signs on either side of Aquarius and Capricorn (Pisces and Sagittarius), and Mars, next in order, received the next two (Aries and Scorpio).
Since Mercury never appears more than one sign from the sun in either direction, it was deemed to rule the two signs on either side of Leo and Cancer (Virgo and Gemini), and since Venus can never be found more than two signs from the Sun, it obtained the rulership of Libra and Taurus.
The discovery of the three "new" planets in modern times provided a dilemma for astrologers, which most eventually resolved by a general consensus declaring Uranus to be Aquarius' ruling planet, while assigning Neptune to Pisces and later, Pluto was given to Scorpio (with some modern astrologers still insisting Pluto rules Aries and not Scorpio).
| Sign | Ruling planet (ancient) | Ruling planet (modern) |
|---|---|---|
| Aries | Mars | Pluto* |
| Taurus | Venus | |
| Gemini | Mercury | |
| Cancer | Moon | |
| Leo | Sun | |
| Virgo | Mercury | |
| Libra | Venus | |
| Scorpio | Mars | Pluto |
| Sagittarius | Jupiter | |
| Capricorn | Saturn | |
| Aquarius | Saturn | Uranus |
| Pisces | Jupiter | Neptune |
- * -- Pluto as modern ruler or co-ruler of Aries is still disputed to this day, though the majority of modern astrologers seemed to have finally settled on Scorpio as Pluto's sign.
Classical astrologers whose methods are rooted in traditional or classical methods do not use any of the outer planets (Uranus, Neptune, and Pluto) as the ruling planets of any of the 12 signs, preferring to stick with tradition instead and only use the traditional rulership scheme.
On the other hand, most modern, psychologically oriented astrologers do in fact use Uranus, Neptune, and Pluto as ruling planets (or co-rulers) of those particular three signs listed above; many others also use the ancient rulers while using the modern planets as the co-ruler of those signs.
Other astrologer do not use any of the planets as sign rulers (Cosmobiologists, Uranian astrologers, Hamburg School, other groups/individuals), preferring to focus more on the astrological aspects and other portions of the astrological chart instead of trying to delineate a certain planet's meaning when it is found within a particular sign or house.
Most astrologers practicing Vedic astrology (Jyotish) only use the traditional rulership system and have been doing so consistently for hundreds and hundreds of years.
