What is a Stellium in Astrology?
In essence, a stellium occurs when you have a collection of the same type of energy in your natal chart.
This occurs when you have three or more planets in a specific zodiac sign or astrological home.
Some astrologers tend to argue that a stellium carries at least four planets in the same sign or house. Still, I think that three planets (or even fixed stars) will undoubtedly create a stellium effect.
