What the planets are in astrology

“The planets are the main characters of the natal chart.”

In astrology, "planets" are the ten bodies studied in the birth chart: the Sun and Moon (the luminaries) and the planets from Mercury to Pluto. Each one symbolizes a psychological function or an area of human experience.

The sign a planet is in shows how that energy expresses itself, the house shows the area of life where it acts, and the aspects show how it relates to the other planets.

Personal planets: Sun, Moon, Mercury, Venus and Mars
Social planets: Jupiter and Saturn
Generational or outer planets: Uranus, Neptune and Pluto
