Hi, First to say that i use initial_frame = 1 and final_frame = 100 and same
thing for clock, that will output in a 25fps animation.


For the orbital mechanics i am well aware that they're not OK, basically i have
not done any work yet, but i will as soon as i correct the orbital geometry
characteristics.

i know too that as far as the geometry goes, the geometry is dependent on the
gravity configuration / placement of the celestial bodies, but once again i plan
to correct this later.

I am only trying to make the camera view OK for the moment.

Best regards. and have all a nice day.
