When you consider the distance what’s a few hundred miles one way or another? ;-)
True, I was surprised that two people independently came as close as we did. That's what I meant by "close enough for government work". I'll also stipulate that my calculation included a bunch of simplifying assumptions like 93*10^6 is a constant distance from earth to sun, that makes our orbit a circle which is nor true but makes the circumference calculation much simpler. Also assumed that the year is 365¼ days of 24 hours each which again is a simplification and fairly close.
What came as no surprise was the hyperventilation about a"NEAR MISS" which turned out to be thousands of earth diameters off target. To me a near miss would have taken out some communication satellites at 22,000 miles out.
What may prove to be a major problem would be the sun going into a phase where cronal mass ejections have replaced sun spots as normal events. If that proves to be true it's only a matter of time playing Russian roulette before we take a direct hit from such with an EMP to move us back several hundred years in the blink of an eye.
