Born 1998–2012, with Neptune in Aquarius? Then a partner’s Mars in Aries or Sagittarius makes the sextile.

To check it by degree: Neptune at 10° Virgo makes the sextile with Mars anywhere from 4° to 16° of Cancer or Scorpio — the 60° angle give or take 6°. The chart goes by sign, but the sextile also forms across a sign line: Neptune at 1° Virgo and Mars at 29° Libra are 58° apart, a semi-sextile by sign.

Years are first entry to final exit, so neighboring rows overlap where Neptune stepped back on a retrograde. Source: NASA JPL DE440.

Between two people

What does Mars sextile Neptune mean in synastry?

Gentle inspiration. The Neptune person adds imagination and sensitivity to the Mars person's plans, and the Mars person helps the Neptune person act on their dreams. Creative projects, music, dance and shared ideals suit this pair, and the sextile works when the two turn inspiration into actual plans.

The usual mistake

Where does Mars sextile Neptune usually go wrong?

Inspiration never becomes a plan. The dream is shared, the action is postponed, and enthusiasm fades into vagueness.

Over time

How Mars sextile Neptune plays out over time

  1. Early on. The Neptune person's imagination and the Mars person's drive meet in a shared idea — a trip, a song, a cause.
  2. Under pressure. The dream needs a plan and a date, or it dissolves into good intentions.
  3. Years in. The bond flourishes when shared dreams get deadlines.

Mars and Neptune at other angles

At any angle: One person's Mars — drive, desire and anger — meets the other's Neptune — dreams, ideals and evasion. Energy and imagination combine, which can inspire romance and art or dissolve into confusion about what either person actually wants.
