Sun opposite Mars means will and drive face each other across the wheel, a source of tension and energy.
The energy for action seems to come from across the way: you meet it in others before fully owning it in yourself.
A keen sense of competition, which pushes you to surpass yourself in contact with worthy opponents.
Provoking or attracting conflicts, then feeling attacked by a world you judge hostile.

Mars in opposition to the Sun is Mars at its closest to the Earth, red and brilliant in the night sky, often retrograde: a sight that returns about every two years.
A Sun in Aquarius facing a Mars in Leo, for example, where the collective ideal would face the wish to assert oneself personally. This polarity is often played out in relationships: identity on one side, action on the other, and other people in between.
Modern astrologers observe that this opposition frequently plays out through projection. The person meets in others the aggression, competition, and initiative they do not dare to own, and reacts strongly. They may find themselves in rivalry with a colleague, a sibling, a partner. A partner in too much of a hurry, a neighbor encroaching on the garden, a competitor copying an idea: these confrontations are also opportunities: they force the person to defend their position, to clarify what they want, and to develop their own courage.
The downside would be chronic conflict. By constantly measuring yourself against others, you can feel endlessly attacked or exhaust your energy in pointless fights. The way out lies in reclaiming: acknowledging your own combativeness, expressing it directly rather than suffering it in others, choosing worthy opponents, a sports match, a debate, rather than daily quarrels.
The person is drawn to assertive, energetic, sometimes domineering partners.
The relationship is lively, passionate, punctuated by arm wrestling. They gain by voicing their desires themselves instead of lending them to their partner. When one person’s Mars faces the other’s Sun, the bond would be magnetic and tense at once, and calls for clear ground rules.
This opposition gives a marked taste for competition and tight negotiation.
The person shows their best against a rival, a challenge, a deadline. Tensions with colleagues or superiors can be frequent. They get a lot in face-to-face dealings, a contract, a deadline, a raise. Choosing environments where competition is regulated, sales, sport, advocacy, turns this energy into an asset.
Their days have moments of high energy and others of exhaustion.
They can get drawn into neighborhood or traffic disputes. They gain by noticing what irritates them in others: often it is a part of themselves asking to be expressed. A physical activity of combat or opposition, fencing, tennis, serves as an outlet.
For tradition, the opposition between the Sun and Mars was one of the most dreaded aspects: two hot, dry bodies face to face would have meant quarrels, rivalries, rashness.
Medieval authors saw in it declared enemies, a reading this site reports without drawing any forecast from it.
Modern astrologers have shifted the emphasis toward relationship and toward what the person refuses to see in themselves. Liz Greene, among others, popularized this psychological reading of oppositions, inspired by Jung’s notion of the shadow. For them, this opposition teaches you to own your own strength instead of projecting it onto others; it would produce people able to stand their ground and defend a cause.
Tradition calls it dynamic: the two functions are said to pull against each other and call for an adjustment, without foretelling anything.

The profile of MarsIt puts will and ardor face to face: the person often meets combativeness in others before owning it in themselves. They show themselves in confrontation. The site accepts this opposition up to 10°. Its downside would be a tendency toward repeated conflicts, which awareness can transform.
This face-off was considered very magnetic: strong attraction, rivalry, a wish to measure yourselves against each other. The bond can be as stimulating as it is exhausting. No relationship is doomed for all that; the key would be to set clear ground rules and to voice a grievance at the moment it arises.
When Mars is opposite the Sun, the Earth passes between the two: Mars is then closest to us and fully lit, visible all night. It is also the period when it seems to move backward in the zodiac, its retrograde phase. This sight repeats every twenty-six months on average.
