Earth's orbit and historical sun-earth distance
Radius calculation
In my code the radius calculation is defined as
o->R =1.000001018*(1.0-e*e)/(1.0+e*cos(f));
where e - eccentricity of the earth's orbit:
f- true anomaly of the sun:
void getSolarPosition … 280.46645+36000.76983*T+0.0003032*T*T;
// M - Mean anomaly of the sun:
double M = 357.52910+35999.05030*T-0.0001559*T*T-0.00000048*T*T*T;
double M_rad = M * degRad;
// e - eccentricity of the earth's orbit …
