Planetary renders, as simple as they may seem are always very cool. You can
achieve a realistic atmosphere using scattering media with a spherical
density (so the air thins the farther it gets from the planet). Perhaps
something like this:
-- POV 3.5 source
sphere {
<0,0,0>, 2.1
pigment {
color rgbt 1
}
interior {
media {
scattering {2, <1, 0.7, 0.7>*1 extinction 1 }
density { spherical }
}
}
translate <0,2,2>
hollow
}
