The values for the semi major axis were obtained from Princeton.edu
and the values for the semi minor axis were calculated by me with
the formula semi minor axis = semi major axis * sqrt(1-e^2):

If looking at https://www.princeton.edu/~willman/p...y_systems/Sol/
( as you did not provided a particular page ),
the semi major axis are not as accurately known as you provided,
neither the excentricity.

So you are just throwing numbers without much sense in it.

The two formulas for X differ indeed:

.05*sqrt(4-3(a-b)^2/(a+b)^2) 1-3(a-b)^2/(a+b)^2)

Cannot you see that a nearly constant X parameter value
means the parameter is useless ?
