To check it by degree: Mars at 10° Taurus makes the opposition with the Sun anywhere from 2° to 18° of Scorpio — the 180° angle give or take 8°. The grid goes by sign, but the opposition also forms across a sign line: Mars at 1° Taurus and the Sun at 29° Libra are 178° apart, a quincunx by sign.

Between two people

What does Mars opposition Sun mean in synastry?

Two strong wills facing each other. The Sun person wants to shine and lead; the Mars person wants to act and win, and each seems to embody what the other is pushing against. The attraction can be immediate and the arguments just as quick. When it works, the opposition turns competition into balance: each person keeps the other honest and energized.

The usual mistake

Where does Mars opposition Sun usually go wrong?

Each sees the other as the thing to push against. The quick arguments are fun until every decision has a winner and a loser.

Over time

How Mars opposition Sun plays out over time

  1. Early on. Two strong wills facing each other; quick arguments feel fun at first.
  2. Under pressure. Every decision acquires a winner and a loser.
  3. Years in. Couples who last turn the rivalry into a partnership aimed outward.

Mars and Sun at other angles

At any angle: One person's identity and purpose meeting the other's drive. This pairing decides whether the two energize each other or compete for the same space.
