Midpoints are the halfway point between two points. When astrologers talk about the Sun/Moon midpoint, for example, they are referring to the point halfway between the Sun and the Moon.
A midpoint is the center between any two points, which in Astrology relates to the center between two planets and/or personal points, including the Midheaven, Ascendant, and the Nodes. This center point is the meeting of planetary energies that becomes active through the process of growth, relating to the passage of time. We relate to the aspects formed by the heavenly bodies through spatial relationship.
The natal midpoints represent our birth traits, our strengths, weaknesses and potential for personal growth. Each midpoint could involve others who are part of our life’s path. Thus, a natal midpoint may apply to family and friends as opposed to the energy being directed to the self. The timing of the events indicated by natal midpoints are activated by progressions, directions, and finally transits as the final touch off point sometime in the future.
