The sky is basically the same as the atmosphere. It starts at the ground and gets gradually thinner as you go higher. Most jet airplanes can't fly higher than about seven miles because the air is too thin up there. Satellites orbit above the sky in space; they have to stay at least a hundred miles high so the air won't slow them down too fast.

Technically, the sky starts at the surface of the Earth and continues in every direction to infinity. That means the sky is as near to or as far away as you want it to be.

Sky is very far from the earth. I think....thousands of kilometres.
