Stellium in Astrology: What It Means When Multiple Planets Align

When three or more planets cluster together in one sign or house, you have a stellium—one of the most powerful patterns in astrology.

A stellium creates concentrated energy, intense focus, and powerful life themes. It's like having a spotlight shining on a specific area of your chart, making that sign or house a central focus of your life experience.

What Is a Stellium?

A stellium (plural: stellia) occurs when three or more planets are grouped together in the same zodiac sign or astrological house. Some astrologers require four planets, but most accept three as the minimum.

Key characteristics:

3+ planets in one sign or house
Creates concentrated energy and focus
Intensifies the themes of that sign or house
Becomes a major life focus area

Stellium vs. Other Patterns

Stellium:

Multiple planets in one sign or house
Concentrated energy and focus
Creates intensity in that area

Conjunction:

Two planets close together
Less concentrated than stellium
Still powerful but more focused

Grand Trine:

Three planets forming a triangle
Different pattern than stellium
Creates harmony rather than concentration

Types of Stelliums

Sign Stellium

When three or more planets are in the same zodiac sign:

Example:

Sun in Scorpio
Moon in Scorpio
Mercury in Scorpio
Mars in Scorpio

Meaning: Intense Scorpio energy dominates your personality. You're deeply emotional, transformative, and powerful. Scorpio themes (transformation, intensity, depth) are central to your life.

House Stellium

When three or more planets are in the same astrological house:

Example:

Sun in 10th house

When planets form a stellium in both sign and house (same sign, same house):

Example:

Sun in Capricorn in 10th house
Moon in Capricorn in 10th house
Mercury in Capricorn in 10th house

Meaning: Extremely concentrated energy. Career ambition (Capricorn + 10th house) is your life's central focus.
