How high is the sky?

The sky starts as soon as the ground ends! There is also no distinct end to the sky. As you go higher and higher, the atmosphere just gets less and less dense very gradually and just fades away, and so there is no well-defined edge where it stops.

You can say however, that 99% of the atmosphere within an altitude of 31 km above sea level (31,000 meters, or 101,706 feet). For comparison, Mt. Everest, the tallest mountain in the world is only 8,846 meters or 29,028 feet. Because the atmosphere is dropping off slowly, you have to go all the way out to 42 km (137,795 ft) if you want to include 99.9% of the atmosphere.

Although it is in fact somewhat arbitrary, the boundary of the earth's atmosphere and outer space is said to be 100 kilometers. When a space craft is re-entering the Earth atmosphere, it is at an elevation of about 120 kilometers that atmospheric drag becomes noticeable.

Interesting.

I wonder how far the stars are?

I wonder if we could touch em if we went that high?

Childish but I've always wondered
 
Off topic but what holds the Atmosphere to the earth? Why doesn't the atmosphere just float away into space? :?

Should I start a new thread about it? :D

I used to think stars were loads of light bulbs plugged into the sky

then I got told that were planets, suns and asteroids

and what colour would it be if we could look up at it from Mars?

The grass is green because of the chlorophyll right? (I dont know if I spelt that correctly or not)

The water in swimming pools is blue because of the chlorine but dont know about the water in the sea.

they paint floors of swimming pools blue also chlorine cleans the water making it clear, seas are only blue on clear days

yes, I think so too, because I once went to seaside and nearly drowned in brown sea on a cloudy day (which was blue earlier)

I'm not specifically sure. But I think the atmosphere is held by Gravity, a law of nature that Allah (Swt) created and controls. =)
