How Our Dominant Planet Calculator Works

Our dominant planet calculator analyzes the planetary rulers of your three most important astrological placements: Sun sign (identity), Moon sign (emotions), and Rising sign (outer personality). Each placement is weighted according to its influence on your overall astrological chart, revealing which planet has the strongest hold over your life path and personality.

Dominant Planet Calculation Method

Sun Sign Ruler: 40% weight - Core identity planetMoon Sign Ruler: 35% weight - Emotional nature planetRising Sign Ruler: 25% weight - Outer personality planet

The planet that accumulates the highest total score becomes your dominant planet. This weighted system ensures accurate results based on traditional astrological hierarchy, where the Sun (core self) has the strongest influence, followed by Moon (inner world) and Rising (social mask).
