Short answer: Your ruling planet depends on your star sign. Aries is ruled by Mars, Taurus by Venus, Gemini by Mercury, Cancer by the Moon, Leo by the Sun, Virgo by Mercury, Libra by Venus, Scorpio by Mars (Pluto in modern astrology), Sagittarius by Jupiter, Capricorn by Saturn, Aquarius by Saturn (Uranus) and Pisces by Jupiter (Neptune).

What does "ruling planet" mean?

In astrology, each star sign is linked to a planet. That planet is said to shape the sign's character. The idea is thousands of years old. It's tradition and storytelling, not science, but it's fun and lots of people love it. The planets themselves are very real.

What does each planet stand for?

  • Sun (Leo): self, confidence. Real fact: a star, not a planet.
  • Moon (Cancer): feelings, home. Real fact: our only natural satellite.
  • Mercury (Gemini, Virgo): talk, ideas. Real fact: the smallest planet and closest to the Sun.
  • Venus (Taurus, Libra): love, beauty. Real fact: the brightest planet in our sky.
  • Mars (Aries, Scorpio): drive, courage. Real fact: red because of iron oxide dust.
  • Jupiter (Sagittarius, Pisces): luck, growth. Real fact: the biggest planet.
  • Saturn (Capricorn, Aquarius): discipline. Real fact: famous for its rings.

Is astrology the same as astronomy?

No. Astronomy is the science of space. Astrology is a belief system about how the sky relates to people. Fun fact: on your birthday, the Sun sits in front of your sign's constellation, so you can't see it that night. More in star sign constellations.
