If the orbital period was 80 minutes then that is 1/1,200,000th of a period and with Earth's circumference being ~25,000 miles that should only be about 0.02 mi

If the orbital period was 80 minutes then that is 1/1,200,000th of a period and with Earth's circumference being ~25,000 miles that should only be about 0.02 miles. Or if the orbital velocity was 17,000 mph and neglecting the height of the orbit, 17000 / 3600 / 250 = 0.018 miles. So either way, about 100 feet.

It was taken from the moon, not low earth orbit.

  Oh right, those numbers made so little sense I assumed we were talking about a different picture, and I wasn't even thinking about the name.
