🧮 Calculation
Definition: Mean lunar apogee — the empty focus / farthest point of the Moon’s mean orbit (Swiss Ephemeris “mean apogee”).
- Mean apogee moves direct ≈ +0.11140°/day (≈ 6′41″/day); full cycle 8.85 years (3,232.6 days); ≈ 9 months per sign.
- “True / osculating” Lilith oscillates up to ±30° around the mean value; “interpolated (natural) apogee” is a smoothed alternative in Swiss Ephemeris.
- Lunar perigee = apogee + 180°.
Usage note: Called Black Moon in French astrology (Joëlle de Gravelaine, mid-20th c.).
