Planetary Rulers
Planetary Rulers of the Zodiac Signs
In astrology, each zodiac sign has a ruling planet. The following shows the planets that rule each sign. Note that we’ve added the classical rulers of signs in brackets. These rulers were assigned to the signs before Uranus, Neptune, and Pluto were discovered. These classical rulers are still used by some astrologers. Note also that some planets rule two signs.

When interpreting a birth chart, the “chart ruler” is usually the planetary ruler of the sign on the Ascendant, or first house. For example, if Aries is the Ascendant, the chart ruler would be Mars. If Taurus is found on the second house, then Venus is said to rule the second house in that particular chart. If Gemini were on the second house, however, then Mercury rules the second house.
