I totally agree, the light position here was just a technical test to see 
how my sunset colours looked, I was just surprised to get a pretty image out 
of it. My final image will probably feature much more conventional lighting 
of the planet.

However, that sun position corresponds to the light position (well except 
the light is directional and the object isn't infinitely far away, but the 
direction is the same relative to the camera). The amount of darkness we see 
is mostly just due to perspective, it's quite a wide angle shot so the lit 
part of the surface becomes very small compared to the dark side. Do not 
underestimate the power of the dark side, etc.
