Stellium

A stellium is a concentration of several planets in one sign or house. It makes a theme visible and concentrated.

How to read it in a chart

A stellium is useful only inside the whole chart. In astrology, everything is read through connections: a sign is refined by a house, a house by its ruler, a planet by aspects, and a forecast by the natal base.

When you meet this term in a reading, ask three questions: which sign or house holds the concentration, which planets are involved, and whether the person can use that theme consciously rather than be overwhelmed by it.

Common mistake

A beginner mistake is to assume that more planets always means "better" or "stronger" in a simple way. A stellium can be a gift, a pressure point, or both.

Use this definition as an entry point into the chart, not as the whole reading.
