| Here is a very simple start:

| camera {location<0,.1,0> look_at<0,0,10000>}
| light_source{<0,1000,0> rgb<1,1,1>}
|
| file://earth
| sphere {<0,0,0>, 1000 pigment{rgb<.35,.35,0>} translate <0,-1000,0>}

| file://sky
| sphere {<0,0,0>, 100000 pigment{rgbf<.8,.8,.8,.25>} hollow}

You would want to use 'color_map' no doubt if this was to all be done with texturing
and not media.
So...

 sphere {<0,0,0>, 100000
  pigment {gradient y color_map {
        [0.0 color rgbf<.8,.85,.9,.05>] // horizon
        [0.1 color rgbf<.7,.8,.85,.125>]
        [1.0 color rgbf<.3,.5,.9,.25>] // zenith
        }}
 hollow}

... might be what you're looking for to adjust colors with.
Obviously the scales aren't correct but I'd guess you know what sizes to make things.
There have been several Earths made by many people over time, some could probably
be found in one of the scene-files newsgroups here.
If you're looking to do something which this doesn't cover don't give up keep asking
questions.
