I have some data about the elliptical orbits of the planets. I have a,e,i,ML,LP,N @ for a specific Julian Century, J2000. I need an equation check:(adsbygoogle = window.adsbygoogle || []).push({});

w = LP - N

EA = MA + e * sin(MA) * (1 + e * cos(MA))

x = a * (cos(EA) - e)

y = a * sin(EA) * (1 - e^2)^0.5

r = (x^2 + y^2)^0.5

v = atan2(y , x)

where

a - Semi-Major Axis

e - Eccentricity

i - Inclination

ML - Mean Anomaly

LP - Longitude of the Perihelion

N - Longitude of the Ascending Node

w - Argument of the Perihelion

EA -= Eccentric Anomaly

r - Radius of the Sun to the Planet

v - True Anomaly
