What does Node square Sun mean in synastry?

A square is an angle of 90 degrees, read as friction. Between Node 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?

Both Node and Sun move fast enough that their positions differ between people born weeks apart, so this aspect is genuinely specific to the two charts.

Both planets here move quickly — Node and Sun change position between people born weeks apart. That makes this aspect genuinely specific to the two charts rather than to a generation, which is true of only 59.9% of the combinations people look up.

What these two planets are doing

Node

The direction of development rather than of comfort.

Sun

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

At 90° the question this pairing raises is whether the relationship pulls forward or back, 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.

Node moves 18.1 times slower than sun, so the faster one sets how long the exact angle holds.

Node and Sun at other angles

The same two planets meet at 3 angles that people search for. Same functions, different relationship between them.
