To check it by degree: Mars at 10° Libra makes the trine with the Sun anywhere from 2° to 18° of Gemini or Aquarius — the 120° angle give or take 8°. The grid goes by sign, but the trine also forms across a sign line: Mars at 1° Libra and the Sun at 29° Capricorn are 118° apart, a square by sign.

Between two people

What does Mars trine Sun mean in synastry?

Mutual encouragement. The Mars person supports the Sun person's ambitions with action, and the Sun person gives that energy a direction. Couples and business partners with this tend to get things done.

The usual mistake

Where does Mars trine Sun usually go wrong?

Getting things done becomes the whole relationship. The pair are productive together and rarely stop long enough to talk about anything else.

Over time

How Mars trine Sun plays out over time

  1. Early on. The Mars person throws energy behind the Sun person's plans from the start, and things begin to move.
  2. Under pressure. The pair act together and quickly when something needs doing.
  3. Years in. Productive and loyal; making time to talk keeps it from becoming all work.

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.
