It all depends on what you think of as "space". If space is above the atmosphere, we're talking about roughly 120-180 miles. Below that, satellites will encounter atmospheric resistance and their orbits will decay faster than if they are launched higher. 280 to 380 miles above the earth is considered "nominal" to sustain orbit with minimal atmospheric resistance. If that is "outer space" to you, go for it. Outer space is actually anywhere there is no earthly atmosphere.

This Q , I think, is not well-thought out! Technically, everywhere over the surface of the earth is in space - so that anyone who lifts oneself up above the ground underneath has 'touched' the space.Only objects placed in space can be related to any distance. It is useful to tell that our earth is conctantly flying in space, wherever it is is carried along with a roaming sun. So there is no distance between the earth and space; it is like asking,"what is the distance between a burning candle and its light". Anyway, thanks for asking- it raised my curiosity as a probing enquiry.

There are actually several answers . . .
Generally, anything above 60-65 miles is considered to be "in space". The Stratosphere is located 10-45 miles up. However a part of Earth's atmosphere called the Ionosphere starts at about 100 miles above the earth, extending to approx. 600 miles above the Earth.
So if you truly wanted to be clear of the Earth's atmosphere in its entirety, go beyond 600 miles to touch true space.

Is this meant to be mean sea level, in which case 65000 feet is considdered a sub orbital drop. 16000 feet is roughly the height at which commercial air travel likes to be, for economy on fule etc. For other things like rockets, they leave our atmosphere at between 60 and 65 thousand feet. Hope this is what you wanted to konw

the space shuttle orbit at 62 miles, that is know as low orbit, where the atmosphere ends, well at the top of Mount Everest the oxygen is almost at zero, Everest is 5 miles high approx, so i guess if you go much higher then the oxygen will run out so as far as mankind is concerned then that's the edge of space

Space is the environment just after the finishing of earth's ozone layer.Thus the answer is zero units.

Using this website, I made the answer around 400 miles but I could be wrong.

Space is not an object or planet that u can reach... we live in the space so I would say 0 miles...
