Your chart ruler is the planet that rules your rising sign: Mars if you have Aries rising, Venus for Taurus rising, and so on through the 12 signs. Its sign and house in your chart show where you most naturally put your energy, which is why two people with the same rising sign can feel very different. You need your birth time to know it, because the rising sign changes about every two hours.
Which planet rules each rising sign?
| Rising sign | Chart ruler | Traditional ruler |
|---|---|---|
| Aries | Mars | Mars |
| Taurus | Venus | Venus |
| Gemini | Mercury | Mercury |
| Cancer | Moon | Moon |
| Leo | Sun | Sun |
| Virgo | Mercury | Mercury |
| Libra | Venus | Venus |
| Scorpio | Pluto | Mars |
| Sagittarius | Jupiter | Jupiter |
| Capricorn | Saturn | Saturn |
| Aquarius | Uranus | Saturn |
| Pisces | Neptune | Jupiter |
Modern astrology gives Scorpio, Aquarius and Pisces to Pluto, Uranus and Neptune; traditional astrology, before those planets were found, used Mars, Saturn and Jupiter. Some astrologers read both.
Why does the chart ruler matter so much?
The rising sign describes how you meet the world, and its ruler shows where that energy goes. With Leo rising and the Sun in the 9th house, your outward warmth is drawn to learning, travel and belief. With Leo rising and the Sun in the 4th house, the same warmth is drawn to home and family.
