A rope is made that fits snugly round a planet at the equator.
It's then decided that it would be much better if it was suspended 1m above the surface.
The inhabitants know the diameter of the planet is 12,000km so how much longer does the rope need to be? :lol
FWIW, a useful website for predictions of visible ISS passes is this one:
http://www.heavens-above.com
Just be aware that the times given are GMT!
The site also gives predictions for other bright satellites including Iridium flares.
