The orbital parameters of most satellites (the TLE data) are freely available, and we can use them to predict the visibility of the satellites. The following is a very simple Python script to predict the visibility of the ISS for the next few weeks.
Flat-Earthers invented many “explanations” about the visibility of satellites. By studying the satellites’ orbital parameters and how they can be used to predict the visibility of the satellites, we know that flat-Earthers’ claims are just nonsense.

Using the current computing power, predicting eclipses is usually done iteratively. We determine the position of the Sun and the Moon at a time and calculate their elongation to determine if an eclipse happens. This same procedure is then repeated many times, each for a different time.
Flat-Earthers insist that nobody can predict eclipses from the position of the Sun and the Moon. They incorrectly believe NASA used the ancient Saros cycle to predict eclipses by calculating the interval between eclipses. A tiny Python script can easily debunk it.
