Hi All,
I'm new to the forum and it's my first question. I'm trying to build a solar system simulation with Unity and currently having problem with marking Vernal Equinox on top of the earth orbit. The position I calculate falls around 16/April/2000 on the orbit, which I know is wrong (should be around March 20).
Below is how I tried calculating this point, but I might have gotten this all wrong... would appreciate any help.
The way I calculated this point is as follows:
Mean Anomaly of the vernal equinox = longitude of the ascending node Ω, and the argument of perihelion ω = 114.20783 + -11.26064 = 102.94719 (also called Longitude of the Perihelion).
Convert Mean to True anomaly and plot the point on the orbit.
What am I doing wrong?
Thanks,
Shay
