What is a planetary midpoint?
A midpoint is the exact halfway point between two planets. It marks a spot where those two energies blend, and any planet sitting on it is pulled into the combination.

What a planetary midpoint is
A midpoint is the degree exactly halfway between two planets — the point where their two meanings meet and blend. On its own a midpoint is a sensitive spot; it becomes loud when a third planet sits on it. This calculator finds the midpoints across your chart and highlights where a planet lands on one.
Why the Sun/Moon midpoint matters
Of all the midpoints, the Sun/Moon midpoint is the one most astrologers read first. It blends your conscious will (Sun) with your instinct and needs (Moon) into a single private signature, and it is a classic point of contact in synastry — planets that fall on a couple's Sun/Moon midpoints often mark a felt sense of "home" between them.
Reading midpoint pictures
A midpoint picture is written "P = A/B" — planet P sitting on the A/B midpoint. The tighter the orb, the stronger the picture, which is why this tool ranks yours by exactness and focuses on those within about a degree and a half. The technique comes from the 90-degree dial tradition (Ebertin's Cosmobiology); read each picture as the third planet expressing the combined drive of the pair.
