By sign
Which signs make Pluto square Sun, generation by generation
Born 1983–95, with Pluto in Scorpio? Then a partner’s Sun in Leo or Aquarius makes the square.
To check it by degree: Pluto at 10° Leo makes the square with the Sun anywhere from 2° to 18° of Taurus or Scorpio — the 90° angle give or take 8°. The chart goes by sign, but the square also forms across a sign line: Pluto at 1° Leo and the Sun at 29° Libra are 88° apart, a sextile by sign.
Years are first entry to final exit, so neighboring rows overlap where Pluto stepped back on a retrograde. Source: NASA JPL DE440.
Between two people

Over time
How Pluto square Sun plays out over time
- Early on. An intense attraction in which the Pluto person seems to want to change the Sun person.
- Under pressure. The Pluto person pushes for change and the Sun person resists, sometimes by walking away for a while.
- Years in. It works when change is invited by the Sun person rather than imposed by the Pluto person.
Who feels it
Who feels Pluto square Sun more, and who gets obsessed?
In a Sun–Pluto square the Sun person usually feels it more: their sense of self is challenged, scrutinized or pressed to change. The Pluto person feels compelled to influence the Sun person and can become fixated on how they live and what they choose. It sits behind many power struggles, and tradition places the obsession on the Pluto side.
Pluto and Sun at other angles
At any angle: Identity meeting transformation. The Pluto person tends to change the Sun person's sense of who they are, for better or worse, and the contact rarely stays neutral. Pluto's slow orbit makes it shared by everyone born near the Pluto person.
