It's not as far as you'd expect (or at least as far as I expected)... at a little over 50 miles obove the surface of the earth is considered the end of the atmosphere... but literally, the whole earth is part of space, so we're all "in" space right now.

Actually it depends on which expert you ask.
In terms of pressure, at 50 miles up the pressure is so tiny that some scientists say that that's where space begins.
But, at 50 miles up there are plenty of molecules and atoms to run into so you can't orbit there, you'll crash and burn within an hour.
You can orbit in the neighborhood of 150 miles up for quite awhile.
Anywhere from 50 miles up and higher is what you should expect for an answer.

The official thickness of the atmosphere is 100 kilometers. The actual physical thickness is closer to 120 kilometers. So it depends what you're looking for. At any rate, after the end of the atmosphere you get space.

For Nasa, about 2 billion dollars. For Burt Rutan about 25 million.

Generally if you are 50 miles above the surface you are considered an astronaut.

to answer your question literally, it would be the smallest amount of distance that you could place between you and the earth's surface.
