ISS is in the low Earth orbit, at about 408 km. Earth's atmosphere technically stretches out as far as 630,000 km. Even outer space is not completely empty.
As for the speeds involved, there's a reason they employ legions of eggheads to figure this stuff out, it takes complex math to pull it off. That's what rocket science is. Also, computers.
Outer space is 3 particles per meter cubed. At the height of 408 km the atmosphere can be neglected for mathematical purposes.
Yes, and those eggheads are strictly compartmentalised, so they themselves don't know shit they are doing apart from crunching the numbers that are in front of them.
