Google Is Your Friend:

(Note that the code shown there is for pov3.1 but it shouldn't be a
problem).
Or, you could experiment with this:
#declare Ball =
sphere{<0,0,0>,0.15 scale <1,1,1> rotate<0,0,0> translate<0,0,0>
texture{pigment{ color rgb<1,0.7,0>}
finish { diffuse 0.9 phong 1}}}
union{
#local Nr = 0; // start
#local N_per_Rev = 500; // Number of Elements per revolutions
#local N_of_Rev = 4.25; // Total number of revolutions
#while (Nr< N_per_Rev*N_of_Rev)
object{Ball translate<1,Nr*0.45/N_per_Rev,0>
rotate<0,Nr * 360/N_per_Rev,0>}
#local Nr = Nr + 1; // next Nr
#end // --------------- end of loop
rotate<0,0,0>
translate<0,0,0>} // end of union
