How many miles of sky is there from earth before you reach space?
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.
