Planetary rulership in astrology describes the affinity between a planet and a sign. Every major planet in astrology has a sign which seems to match it. The energy of Aries, for example, is very similar to the planet Mars. While Mars is in Aries, he is “at home” and able to more comfortably express his basic nature.
Committing rulerships to memory makes the task of reading charts much easier!
Table of Planetary Rulerships
|Mercury||Gemini and Virgo|
|Venus||Libra and Taurus|
*Uranus, Neptune, and Pluto are relatively new on the planetary “scene,” having been discovered only after the development of telescopes. Therefore, Aquarius, Pisces, and Scorpio also have traditional rulers among the seven visible planets.
Some astrologers, such as Rob Hand, believe that Uranus, Neptune, and Pluto are impersonal energies, and as such, they rule no signs. They exclusively use traditional rulerships.
I encourage you to learn both modern and traditional rulerships and use the system with which you are more comfortable. I use both because that works for me. Use what works for you.
