I'm not sure I follow. The sun's disk is 5 degrees in radius from earth, the 
brightness of it doesn't make it any larger (like I say you can use a filter 
to see that all the suns direct light comes from that disk). Povray can 
simulate a circular area light of the same angle and brightness. The only 
reason I'm using a larger one is because I'm taking some artistic license, 
in truth a small ball on a table would have an almost perfectly sharp 
shadow.
