Dominance

Dominant planets are those which form an aspect to either the Ascendant, Medium Coeli or both. The conjunction is regarded as being the most significant, followed by the opposition, square, trine and sextile. According to this scheme the planet which forms the most important aspects is considered to be the most dominant planet. The characteristics of dominant planets are prominent in the horoscope and have a powerful influence on the individual concerned.

Some astrologers also consider that the following features indicate that a planet is dominant: planets that are in the first half of a cardinal house, i.e. the first, fourth, seventh and tenth house; elevated planets i.e. those found closest to the Medium Coeli; and finally any planet which is conjunct a house cusp.
