"the light blue indicates the portion above the ecliptic plane, and the dark blue the portion below the ecliptic plane"
Based on your implied Christianity on your profile page, take eight minutes and forty-six seconds to view this (Enoch, Messenger to the Fallen Angels. Part One) and let us know if you agree...
C/2012 S1 (ISON) Orbit Diagram ( Current )
I'm not sure what exactly it was that you were tryuing to enlighten us with, but just so you know, after sifting through that web page from JPL, the vital information you really need is at the bottom.
Since you might not be able to extract that information, I have done it for you:
Close-Approach Data
2013-Dec-26 20:23
Time Uncertainty - (days_HH:MM) 00:12
Body Earth
Nominal Distance (AU) 0.430597325537957
Minimum Distance (AU) 0.430298254046287
Maximum Distance (AU) 0.430896449411539
V-relative (km/s) 47.5108311739296
V-infinity (km/s) 47.5107009325476
Time Uncertainty (minutes) 11.6325082661853
It is left to you to do the math and discover what 0.430298254046287 AU is in miles (or km if you prefer to function in metric..)
Or you can accept my quick off-the-top-of-the-head-estimate of about 37 MILLION miles.
All from data on a page you linked us to.
You're welcome.
