Typicaly, the Sun is at a very large distance from your scene objects. It have 
an aparant radius.
You use the "parallel" keyword and point it to the center of your scene. This 
simulate a light source that is very far away.

You use an area_light with circular. You can also use "orient" to make sure the 
light aray is always perpendicular to the location tested.
circular with orient create a "spherical" area_light.

If you can see your sun, directly or trough reflection(s), add a looks_like to 
make it visible.
