Method Details
- moonEclipticCoordinates
  
  public static Vector3d moonEclipticCoordinates(double julianDate, Vector3d out)
  
  Algorithm in "Astronomical Algorithms" book by Jean Meeus. Returns a vector with the geocentric ecliptic longitude (λ) in radians, the ecliptic latitude (β) in radians and the distance between the centers of the Earth and the Moon in kilometers.
  
  Parameters:
  
  julianDate - The julian days since J2000.
  
  out - The output vector with geocentric longitude (lambda) [rad], geocentric latitude (beta) [rad], distance between the centers of the Earth and the Moon [km].
  
  Returns:
  
  The out vector with geocentric [lambda, beta, r] in radians and kilometres.
