There are three groupings of the planets defined by energies:
PERSONAL PLANETS-Sun, Moon, Mercury, Venus and Mars (explains why these are the focus in natal charts). LEO, CANCER, GEMINI, VIRGO, TAURUS, LIBRA, ARIES
The makeup of the orbit around the Sun
Getting deep into what makes us human which allows for connection. Pure emotion and innocent ignorance. There is a "mission" to find true love or purpose.
SOCIAL PLANETS-Jupiter and Saturn-SAGITTARIUS AND CAPRICORN
The further ones of the orbit that are spread out
Using personal energy to use in the outside world for gain of knowledge and experience. Substituting connection for progression of the self through bigger matters. Widespread view.
TRANSPERSONAL PLANETS-Uranus, Neptune, and Pluto-AQUARIUS, PISCES, AND SCORPIO
The outer most ones that hide in the background
“Out of this world" is an almost perfect description. Reaching into concepts outside of the familiar to show what is out there and to get clarity of some sort. Curiosity about the unexposed.
