What is a stellium?
A stellium is the clustering of three or more planets within the same sign or house. It is the astrological signature of a person whose life concentrates powerfully on one theme.
Sign stellium
Planets in one zodiac sign amplify that sign's traits and turn its ruler into a major chart force.
House stellium
Planets in one house spotlight that life area — career, love, family — as the arena of your focus.
The gift and edge
Stelliums bestow deep talent and intensity, but also over-concentration: too much energy in one basket.
Interpreting a stellium
The stellium's sign tells you the flavour of the focus; its house tells you where it plays out; its planets describe how you express it.
- • Fire stellium — action, passion, leadership and impulsiveness.
- • Earth stellium — practicality, discipline, building and material focus.
- • Air stellium — ideas, communication, social life and mental energy.
- • Water stellium — emotion, intuition, depth and psychic sensitivity.
- • With the Sun included — identity is fused with the stellium theme.
- • With Saturn or Pluto — the theme is intensified with karmic weight.
