I got 22,397,550 miles in 14 days
Orbital path length is (93,000,000 * 2 * π) = 584,336,233 Miles per year, or (584,336,233/365.25) = 1,599,825 Miles per day or (1,599,825/24) = 66,659 miles per hour which is our orbital velocity.
Diameter of Earth is 7,926 miles so (22,397,550/7926) or the "near miss" was equivalent to about 2,825 Earth Diameters. Close enough for government work!

When you consider the distance what’s a few hundred miles one way or another? ;-)
