Most astrologers count three or more planets in the same sign or house as a stellium, though some require four. The most chart-defining clusters usually involve the Sun, Moon, and the personal planets (Mercury, Venus, and Mars).
A sign stellium (three or more planets in one zodiac sign) shapes how you operate, making that sign's traits dominate your personality. A house stellium (three or more planets in one house) shapes where your energy goes, making that life area a central focus.
A stellium is neutral. It concentrates energy and focus, which can become genuine mastery and clear direction, or tip into obsession and the neglect of other life areas. Whether it is a gift or a challenge depends on how you work with the energy.
Generate an accurate natal chart with your birth date, time, and place, then count the planets sitting in the same sign or house. Three or more is a stellium. An accurate birth time matters because it sets your houses and Ascendant.
