How many miles to outer space?
Approximately 62 miles.
If you mean the International Space Station, 220 miles, or 350 kilometers. I f you mean space, that has been defined in many ways, 60 miles, 62 miles, 80 miles, 100 miles. For that answer you need to specify what you really need to know. Like where is there no more air, what is the International definition of the beginning of space. At what altitude has a person considered to have been in outer space?
This depends on how fast you are going first of all, so if we just assume you are travelling in a space shuttle, that travels at 17,500 miles per hour (about mach 11-12) we take that and divide how many miles Earth's atmosphere is. Seeing as how Earth's atmosphere is only 300 miles thick, if we round to the nearest thousandth of a second it will take around 1.02 minutes to fully exit the atmosphere…
