The headline said three. The degree rule says four, and the rule wins.
A birth-chart point within about 3° of 2.76° Taurus or Scorpio counts, and so does a point within about 3° of a hard square to that axis. Conjunction and opposition are the tightest contacts. Squares come next. Anything wider is background noise.
1. Taurus. The Moon lands here, so a natal Sun, Moon, rising sign or Venus anywhere from 0° to about 6° Taurus sits inside the orb. This is the sense-of-security hit — the body, the budget, the routine.
2. Scorpio. The Sun opposes from 2.76° Scorpio, catching the same points on the other side of the axis. Where Taurus guards, Scorpio audits: shared money, trust, the thing you have not said out loud.
3. Leo. 2.76° Leo sits square to the Taurus Moon, and points near 0° to 6° Leo square the Scorpio Sun on top of that. The pressure shows up as pride — defending a choice because you made it, not because it still serves you.
4. Aquarius. 2.76° Aquarius squares both ends of the axis as well. Here the tension reads as distance: staying busy, staying logical, staying far enough from the conversation to avoid it.
Why four and not three? Taurus and Scorpio qualify on the exact opposition. Leo and Aquarius qualify on the square. You cannot drop one fixed sign without breaking the geometry that admitted the others.
What about a fifth? Mars sits at 15.64° Leo and Saturn at 9.67° Aries — both too far from 2.76° to pull a whole new sign into the tight-orb list on their own. Saturn's 23° separation from the Moon is wide. So the honest count is four. Check your own placements with the transit chart calculator before you adopt any label.
