Dominance and prominence are designations given to planets. These designations help determine which planets have the most influence in your sidereal birth chart. Planets in your sidereal birth chart represent the people in your life and your experiences in relationships with them. Dominant and prominent planets are the people and relationships that have the most influence in your life.
Dominant planets are calculated by examining the concentration of signs in your sidereal birth chart. Dominant planets say who the people are that have had control of your circumstances and have had responsibility for you. They tell you what the dominant experiences have been in your relationships.
Prominent planets are calculated by examining the position of planets in your sidereal birth chart (proximity to the Ascendant, Midheaven, or Descendant.) Prominent planets say who has had power in your life and over your environment. Prominent planets often explain why you might resonate with the interpretation of certain sidereal zodiac sign(s) even though you do not have any planets occupying those signs. It is because the ruler of said sign(s) are place prominently in your sidereal birth chart.
There are so many ways to understand the dominant and prominent planets in your sidereal birth chart. In sidereal planet, this planet/these planets is your rightful chart ruler. The ruler of your ascendant (rising sign) is not always your chart ruler. It’s not for most people.
Jupiter in sidereal Sagittarius being most the prominent AND dominant planet in my birth chart means that I always have Jupiter figures entering my life, like godfathers. Protecting me, encouraging me, sometimes giving me money, counsel, or connecting me with other people.
They are usually men who are older than me, like an uncle or big brother. Even in my family, there has always been way more men than women who were regularly present and close.
The most dominant planet in your sidereal birth chart is the planet that has the most influence based on the signs occupied in your birth chart. The most prominent planet in your chart is the planet that has the most influence based on the position it occupies.
Sometimes the most dominant planet is also the most prominent planet. Sometimes it’s not. Some people don’t have a most dominant or prominent planet. Sometimes you have more than one in each category.
Prominence As The Missing Piece
The most prominent planet your sidereal birth can be the most telling (if you have one) because it usually explains why you identify with certain signs that are not occupied in your birth chart.
For example, you might not have any placements in sidereal Scorpio or Aries, but Mars is the most prominently placed planet in your birth chart. Mars might be in the same sign as your Ascendant. Maybe it’s the only planet conjunct your Moon.
I happen to have the same planet as my most dominant (by signs) and most prominent (by position/place.) You may have the same planet as your most prominent & dominant if the ruler of your ascendant is in the same sign as your ascendant (sidereal Libra rising + Venus in sidereal Libra.)
If you have a planet in the same sign as the Midheaven, then that planet may be the most dominant and prominent.
Remember, planets are people and our relationships with people. Sidereal zodiac signs articulate our personal hierarchy of relationship (survival) priorities. So, if Mars is your most dominant planet, that means Mars is at the top of your hierarchy.
That means that Mars, experiences of alienation (differences can’t be concealed) and abandonment, are significant themes in your relationships. These are the experiences you’ve had to survive. These experiences have defined your relationship priorities which are also your survival priorities.
This would also be true if Mars is your most prominent planet.
