Mars square your natal Sun

Mars square natal Sun is about ambition, irritation, willpower, competition, and courage under pressure. Transiting Mars, carrying drive, heat and conflict, stands 90 degrees from your natal Sun, the seat of identity and vitality.

A square is a quarter of the circle, 90 degrees. Signs in square share their pace, cardinal, fixed or mutable, but not their element, so the two pull against each other: friction that tends to force a move.

A one-minute story

The Wandering Stars

How the moving planets were watched, named and found, and what a transit is.

Planet means wanderer.

How long does Mars square natal Sun last?

Around four days, as Mars moves about half a degree a day. When Mars turns retrograde near the point, the contact can come and go for two or three months.

How often: Twice in every circuit Mars makes of the zodiac, which takes about two years.

Is Mars square natal Sun good or bad?

Challenging but productive: a square is friction at ninety degrees, and it tends to force a decision or an action about ambition.

How Mars square natal Sun shows up in real life

With Mars it tends to arrive as urgency, heat, effort or a quarrel. Where it lands is the territory of your natal Sun:

It can come as an outer event, an inner pressure, a repeating conversation or a change in the body, and it is loudest when it is applying and exact, quieter as it separates, and louder again if a retrograde brings it back.

Timing, orb and chart context

Most astrologers feel a transit from about a degree before exact to a degree after for the fast planets, and allow two or three degrees for the slow ones. It builds as it approaches, peaks at the exact hit, and fades as it separates.

How to work with Mars square natal Sun

Act, but do not lash out. Choose the clean fight: exercise, hard work, decisive repair, or honest leadership.

How to know if Mars square natal Sun is active for you

Find the degree of your natal Sun in your birth chart and watch for transiting Mars to reach 90 degrees away, in either direction. Within about a degree it is at its strongest.

The house your natal Sun occupies narrows it further: in the tenth it is work and reputation, in the seventh a partner, in the fourth home and family.

The lore of Mars

Mars is the lesser malefic, second only to Saturn in the trouble the old books said it could bring: heat, iron, blood and war. The same books gave it its virtues, courage and the strength to cut what has to be cut, which is why surgeons and soldiers were both counted its children. It takes about two years to circle the zodiac.
