R max = maximum distance planet to sun, in millions of kilometers (Mkm)
R min = minimum distance planet to sun, in Mkm
semi-major = semi-major axis of ellipse (a = R max + R min / 2), in Mkm
eccentricity (e = c/a, where c = R max - R min / 2)
This data on the dimensions, R-max and R-min in Mkm, is taken
from (Moore/Hunt, 1983),
and the eccentricity calculated
therefrom. More accurate values of e are given
on another page.
