The eccentricity constant of solar objects

The eccentricity constant X of solar objects can be calculated by the formula
.5*sqrt(4-3(a-b)^2/(a+b)^2) where a = the semi major axis and b = the semi minor axis.
The eccentricity constant X of nine planets is equal to 1.0 as follows:


So you say a circle has the eccentricity constant 1.0.
Interesting.

..5*sqrt(4-3(r-r)^2/(r+r)^2) = .5*sqrt(4) = 1
