Where Does Outer Space Begin?
Sometimes really interesting questions can be asked very simply. For example, where does outer space begin?
This seems like a straightforward question.
We live on the surface of Earth, shielded from the vacuum of space by a blanket of air.
Distance from earth to space station in km
But we know that our planet’s atmosphere gets thinner, less dense, with height. So it makes sense that at some altitude, the air becomes so tenuous that you’d essentially be in space. How high up is that?
The thing is, it depends on what you mean by “space,” which is a term that’s surprisingly hard to define.
Currently, the generally accepted demarcation line is 100 kilometers above Earth’s surface, but that value hasn’t been rigorously defined mathematically or physically. Moreover, when rigor is applied, a “space starts here” demarcation of 80 km is arguably a better height to use.
