What is a stellium in astrology?

A stellium in astrology is a placement in a birth chart where three or more planets are in the same zodiac sign or house. This creates a concentration of energy in that area of the chart, making it a focal point for the individual's life path and experiences. Stelliums can occur in any of the 12 zodiac signs or in any of the 12 houses, and the interpretation of a stellium depends on the specific planets involved and the sign or house in which they are located.

Stelliums are believed to have a significant influence on a person's personality traits, strengths, challenges, and life purpose. They can indicate areas of intense focus or talent, as well as potential challenges and conflicts that may arise in those areas. Some astrologers also believe that stelliums can represent a key theme or lesson in a person's life, one that they are meant to explore and master in order to achieve their highest potential.
