In astrology, a Midpoint is the mathematical halfway position between two planets, angles, or other chart factors. Midpoints are calculated from zodiacal positions and may be examined as additional reference points within a natal chart. Astrologers may interpret a midpoint by considering planets or chart points that closely contact it, particularly through conjunction or opposition. Midpoint analysis is used to explore how the symbolism of two chart factors may combine or become emphasized through a third factor, adding another layer of structural and interpretive detail to the chart.
