By sign
Which signs make Mars square Uranus, generation by generation
Born 1995–2003, with Uranus in Aquarius? Then a partner’s Mars in Taurus or Scorpio makes the square.
To check it by degree: Uranus at 10° Taurus makes the square with Mars anywhere from 2° to 18° of Leo or Aquarius — the 90° angle give or take 8°. The chart goes by sign, but the square also forms across a sign line: Uranus at 1° Taurus and Mars at 29° Cancer are 88° apart, a sextile by sign.
Years are first entry to final exit, so neighboring rows overlap where Uranus stepped back on a retrograde. Source: NASA JPL DE440.
Between two people
What does Mars square Uranus mean in synastry?
Volatility. Tempers flare without warning, plans are abandoned, and each person resists being controlled by the other. The attraction can be as unstable as it is strong. Sudden decisions — moving, quitting, breaking up — can be made in the heat of the moment. Agreeing to a cooling-off period before any big change protects the relationship from its own impulses.
The usual mistake
Where does Mars square Uranus usually go wrong?
Impulsive exits get decided in the heat of a fight — moving, quitting, breaking up — with no cooling-off rule to catch them.
Over time
How Mars square Uranus plays out over time
- Early on. Electric and erratic: sudden attraction, sudden fights and plans that change by the hour.
- Under pressure. Tempers flare without warning, and moving out or quitting gets decided in a single evening.
- Years in. It lasts only with a cooling-off rule for major decisions and plenty of independence on both sides.
Mars and Uranus at other angles
At any angle: One person's Mars, drive and desire, meets the other's Uranus, the urge for freedom and change. The combination is electric: fast attraction, sudden decisions and very little patience on either side.
