Key Formulas and Calculations

Asteroid chart calculations are based on astronomical ephemerides, which provide the exact positions of celestial bodies. While you don’t need to manually calculate positions, here’s what the tool does behind the scenes:

  1. Orbital Calculations:
    Each asteroid’s orbital elements (semi-major axis, eccentricity, inclination, etc.) determine its position at a given time.
  2. Conversion to Ecliptic Coordinates:
    Asteroid positions are converted to longitude along the zodiac ecliptic to assign zodiac signs.
  3. House Placement:
    Asteroid positions are projected onto the natal chart houses based on your birth time and location.
  4. Aspects:
    Angular relationships between asteroids and planets are calculated:
    • Conjunction: 0° ± orb
    • Opposition: 180° ± orb
    • Trine: 120° ± orb
    • Square: 90° ± orb

These calculations provide a detailed astrological map of the subtle influences each asteroid exerts in your chart.

Step-by-Step Example

Example: Calculate Chiron and Ceres placements
