The ten planets of astrology each stand for one inner drive — the Sun for identity, the Moon for emotion, Mars for action. In a natal chart, the sign and house each planet sits in show where and how that energy plays out.
What the ten planets drive
The Sun is identity and self, the Moon emotion and instinctive response, Mercury thought and communication. Venus is love and taste, Mars desire and drive — these five are the personal planets.
Jupiter is expansion and fortune, Saturn responsibility and limits — the social planets — while Uranus, Neptune and Pluto are generational planets that work across a whole cohort, standing for change, ideals and deep transformation.
Why placement matters
The same planet takes on a different color depending on the sign it sits in, and a different arena of life depending on the house it occupies. Mars in Aries acts as direct, fast drive, and its house decides whether that force turns toward work, relationships or self-expression.
Frequently asked
It gives the broad direction but only a part. The Sun is the center of identity, and your real temperament shows only when you read it together with the Moon, Mercury, Venus, Mars and the Ascendant.
The Sun through Mars move quickly, so they are personal planets that differ by individual; Uranus through Pluto move very slowly, so they are generational planets shared by a cohort. For generational planets, the house they occupy matters more.
