A stellium is an astrological term referring to the alignment of three or more planets in a single astrological house or sign in a natal chart. The term is derived from the Latin word "stellium," meaning "a group of stars." In Hebrew, it is translated as סטליום. In Spanish, it is known as stelium, and in French, it is called stellium. This alignment is considered significant in astrology as it is believed to intensify the influence of the involved planets, houses, or signs, creating a powerful focus in the individual's life. The interpretation of a stellium depends on the specific planets involved, the houses they occupy, and the aspects they form with other planets in the chart. Astrologers often view a stellium as a key indicator of a person's strengths, challenges, and life themes.
