Continuing on my physics model theme, something else...

Basically the orbiting thing has an initial velocity which keeps it from
smashing into the "planet." There's a little homemade motion blur which I
think does a pretty good job, especially at the speed the thing gets to.
And its all POV, there's no post-processing.

This is a really neat anim, as are your other two. I'm really intrigued when
POV is used for physical simulations.

nice, forget the motion blur, make it slower, and throw a extra 20 orbiters
at it - that would look captivating - especially if you can get the
collision detection and have them bouncing off each other

this is actually a LONG stride from the previous animation... the center
ball actually belongs in the same array as the rest, treated exactly the
same.  I was going to get rid of it but the other balls kept floating off
collectively and I couldn't keep the camera on 'em.  So I just added one
with a big radius at the origin, viola: gravity anchor.  There seems to be
some realistic bouncing and collisions, I think I'm getting closer...

I like the way the mpeg compression artifacts are distorting the surface of the
large gray ball when the small ones bounce across it.  Looks like they drag
across as though going into a gelatin.

Yeah! - that is capitivating :)

really very good - now how about adding a collision effect, either a texture
effect (like a pigment or normal ripple) or a little flash to highlight all
the collisions or a sound, stick 2 of these side by side and let everything
interect

i am really impressed that you actually answered my request, :))

I think the problem you are running into with all the balls floating off is
that the balls have a net velocity that is non-zero.  The first thing your
code should do on the first frame is figure out the net velocity of the
balls and then modify the velocities of the individual balls so that the net
velocity is zero.
