Astrology basics

Chart dominant

The chart dominant is the planet (or sign) that carries the most weight in a given chart — through its number of aspects, its placement on a key chart point, or a strong cluster of planets in one sign or element.

Unlike the chart ruler (which follows directly from the ascendant), the dominant is worked out by weighing the whole chart — finding it can be somewhat subjective, and different astrologers may use different methods to weigh each factor.
