To check it by degree: Mars at 10° Libra makes the square with Venus anywhere from 2° to 18° of Cancer or Capricorn — the 90° angle give or take 8°. The grid goes by sign, but the square also forms across a sign line: Mars at 1° Libra and Venus at 29° Sagittarius are 88° apart, a sextile by sign.

Between two people

What does Mars square Venus mean in synastry?

Strong attraction with a sting in it. What one person finds exciting the other finds slightly too much, or not quite enough, and the push and pull keeps interest high. The difficulty is that tension which feels like chemistry at the start can feel like unfinished arguments a few years in.

The usual mistake

Where does Mars square Venus usually go wrong?

Tension that felt like chemistry becomes a backlog of unfinished arguments; the pair keep reading the friction as proof of passion.

Over time

How Mars square Venus plays out over time

  1. Early on. Strong attraction with a sting: what excites one feels a bit much, or not enough, to the other.
  2. Under pressure. Unfinished arguments pile up and get mistaken for passion.
  3. Years in. It works when the pair talk about what each actually wants in affection and desire.

Mars and Venus at other angles

At any angle: The classic attraction pairing: what one person pursues and what the other finds appealing. It says a lot about chemistry and far less about whether two people can live together, which is why it is so often over-read.
