A stellium is a group of three or more planets placed together in one house or one sign.

Below are two examples of a stellium. The first is a stellium in a house, the 9th House. Our second chart example shows a stellium in the sign of Gemini. This individual’s stellium actually contains 5 planets!

Every planet represents a part or a mechanism of our mind or spirit.

Mercury, for instance, is our planet for logical thinking and communication. Venus? This is the planet that urges us to form bonds with others.

In a sign stellium, the mental and emotional processes of each planet involved meld together, forming a kind of supergroup where they all operate through the same sign.

With so much energy concentrated in one place, a stellium is a “hot spot” in your chart pointing you toward the qualities and motivations of a sign that can’t be ignored.

Because their chart shows an emphasis in Sagittarius, the Sagittarian characteristics of a search for the meaning of life, freedom to explore, adventure, impulsivity, and optimism may be dominant for them when it comes to their thinking and communication style, their take on relationships, how they connect with a higher power, and even the core of who they are, their ego.

The planets of a sign stellium will work together in harmony, all complimenting the efforts of one another.
