Where does the sky start?

[Elastoman]

OK, seems like a stupid question when your 7 year old asks you, but where does it start?

I know that birds and planes fly in the sky, as do kites and flags. I also know that my kids blow bubbles that drift up into the sky - or do they start there and merely move upwards within the sky?

Does it start in a different place for me than for a snail or a worm?

Maybe it's anything that's not on the ground? Or anything between the ground and space?

ground to +/- 50 miles

I don't think ground to -50 miles could be considered sky though

Thanks mmcp42. Does that mean then that the stars, moon, sun, etc are not in the sky, but beyond it?

If it starts at the ground, is that on the ground or just above it - 1mm? 1nm? 1 angstrom?

ooooh! More questions!

If we are getting deep , tell me where does the sky end

Surely that would be the same place as it starts, just from the other side!

The "sky" is something we can view from the Earth surface. From our point of view, it is our atmosphere; that's where all our weather and natural gases are contained. That extends up to 50 miles away from the surface and is the part that interests meteorologists such as your's truly. The reason why the sky appears as blue during the day time is the scattering of the blue end of the light spectrum.

Beyond that we enter the cold and very vast emptiness that is Space, with suns, comets, planets occupying that part. I don't call that part as the sky, to me that is "outer space" and is something that interests people who are into astronomy.

er, sorry I was using +/- as a shorthand for ~ (approximately)
but ~ is 1 character and + / - is 5 (with spaces)
er failed

I always thought the sky started at the horizon.

 

[Rozzy]

the ground starts where skyscrapers finish! everyone knows that!

 

[towershot]

Is anyone using a CPL to equate these answers.........
