Sun trine Mars

Aspect · trine · default orb 8°

In the natal chart the Sun signifies the principle of identity and visible authority — what is shown to the world, the part of life that signs its own name. The Mars signifies the principle of decision and severance — appetite, contention, the part of life that cuts and presses forward. When their longitudes form a harmonious one-hundred-twenty-degree flow across signs of the same element; the configuration runs without resistance, which classical sources warn can also mean it runs without urgency, the chart carries the resulting configuration as a structural feature of its temperament — present in every house and angle that either body touches.

Identity meets appetite. The Sun shows; Mars cuts. Their contact describes the chart's contested terrain — where the will pushes against resistance, and how directly it does so.

The trine runs without resistance. Same-element signs allow Sun and Mars to flow into one another's expressions naturally. The classical caution: a trine that is never tested may also never be developed. The contact is a gift the chart can spend or, just as easily, leave on the shelf.

The configuration is in orb when the angular separation between Sun and Mars falls within 8° of an exact trine (Lilly's classical orb; Netra's Aspects view defaults match this and can be tightened in the chart preferences).
