Core Function:
Marks the soul’s forward growth and unexplored destiny, directly opposite the South Node.
Astrological Role:
In charts, the North Node highlights new karmic lessons, drawing one toward unfamiliar experiences.

🧮 Calculation
Definition: Ascending node of the Moon’s orbit on the ecliptic (Moon crosses from south to north ecliptic latitude).
- Mean node: retrograde, −0.052954°/day (≈ −3′11″/day); full cycle 18.6 years (6,798.4 days); ≈ 18.6 months per sign.
- True (osculating) node: oscillates up to about ±1°45′ around the mean node and can briefly move direct.
- Eclipses occur only when a lunation falls within ≈ 15–18° (solar) / ≈ 10–12° (lunar) of a node.
Usage note: The nodal axis is the eclipse axis; the draconic month is 27.2122 days.
