Thanks for the comments. Do I need to scale the density file to the 
scale of my scene?

The "sky" is also meant to place the opposite side in shade in order to 
produce "night". I've tried other methods like placing a sleeve around 
the lamp, but due to radiosity the opposite side is then never fully in 
the dark. I.e. the "bright" side casts reflected light onto the supposed 
"dark" side.

As for loss of occupancy, you're assuming people want to live in zero G. 
Only the areas near the surface have suitable "gravity".

The "sky" does look ugly though.
