How to compute planetary positions Paul Schlyter, Stockholm, Sweden d = 367*y - 7 * ( y + (m+9)/12 ) / 4 + 275*m/9 + D - 730530 (this is a floating-point division) N = longitude of the ascending node i = inclination to the ecliptic (plane of the Earth's orbit) w = argument of perihelion a = semi-major axis, or mean distance from Sun e = eccentricity (0=circle, 0-1=ellipse, 1=parabola) M = mean anomaly (0 at perihelion; increases uniformly with time)
