Stellium
Three or more planets gathered in one sign or one house, drawing much of a chart’s weight to that one place.
Meaning
A stellium is a gathering: several planets in the same sign, or in the same house. Where most charts spread their planets around the wheel, a stellium puts much of the chart’s weight in one place, and that sign’s style or that house’s area of life tends to become a central theme.
A stellium in a sign colours the character. With four planets in Virgo, attention to detail, usefulness and craft run through many parts of the personality, from the way one loves to the way one works. A stellium in a house points to an area of life: several planets in the seventh house set partnership, and the meeting with others, at the centre of things.
Its strength is focus: depth, persistence and real competence in its field. Its risk is imbalance, so much invested in one place that other parts of life get little, and the signs or houses left empty can feel unfamiliar. The planets inside a stellium also act on each other, usually through conjunctions, and the planet that rules the sign, their dispositor, gains importance as the one they all answer to.
Schools differ on the count. Many astrologers today speak of a stellium from three planets; others ask for four or five, or for the planets to be joined to one another by conjunction rather than simply sharing a sign.
In practice
- The Sun, Mercury and Venus together in one sign are common, since Mercury and Venus never stray far from the Sun; a gathering of planets that do not travel together is rarer.
- Uranus, Neptune and Pluto move so slowly that their part in a stellium is shared by everyone born around the same time. What makes it personal is the house it falls in and the faster planets that join it.
- Read the sign and the house together: a stellium in Capricorn in the fifth house brings Capricorn’s patience and ambition to creative work and play.
- When the Sun is inside a stellium, the planets closest to it are combust in traditional terms, their voices merged into the Sun’s.
Origin and history
Older English texts speak of a satellitium, from the Latin satelles, an attendant: planets gathered like a retinue around one figure. The shorter stellium, from the Latin stella, a star, appears in James Wilson’s Complete Dictionary of Astrology (1819) and has since become the usual word.
How Ulune calculates it
- Ulune counts the ten planets, from the Sun to Pluto. Three or more of them in one sign, or three or more in one house, make a stellium; Chiron, the nodes, the asteroids and the angles are not counted.
- No orb is needed: sharing the sign or the house is enough, so a stellium can stretch across most of a sign.
- A stellium by sign and one by house are listed separately, so the same planets may appear twice.
- The Table’s Patterns part lists every stellium, At a glance in the side panel shows up to two, and the wheel’s Stelliums overlay marks them.
- Without a birth time, a stellium by house, or one whose planets may change sign during the day, is marked ~.
