What does Neptune square Sun mean in synastry?

A square is an angle of 90 degrees, read as friction. Between Neptune and Sun it describes how the two functions those planets stand for meet — reliably enough to be worth reading, common enough to be worth checking against chance.

How common is this aspect?

It occurs in 8.89% of random pairings — the orb is 8 degrees, so the window is two bands of the 360-degree circle. In a chart comparison with dozens of planet pairs, several aspects appear for arithmetical reasons alone.

Is this aspect about us or about our ages?

Neptune spends about 14 years in one sign, so everyone born in that window shares its position. This aspect largely describes the age difference between you, not something specific to the pairing.

Neptune takes about 14 years to cross one sign. Everyone born inside that window has it in the same place, so this aspect is largely a description of the age gap between two people rather than of the relationship.

Put concretely: if you and your partner were born a decade or more apart, this aspect was decided by the calendar before either of you existed. Why 40.1% of searched aspects work this way →

What these two planets are doing

Neptune

Idealisation and the blur between seeing and imagining.

Sun

The core identity — what a person is when nothing is being performed.

At 90° the question this pairing raises is whether either is in love with a version rather than a person, set against whether each is comfortable being seen as they actually are. A square puts those two demands at odds rather than in agreement, which is why this aspect is read as work rather than ease.

Neptune moves 168.7 times slower than sun, so the faster one sets how long the exact angle holds.
