AW: [Starry Night] Rings for Jupiter, Uranus?

[Dr.Michael Schurz]

Asteroid belt IS already available. I downloaded a file containing orbital data for 17000 (seventeen-thousand!) asteroids, loadable for SNpro. But it's not feasible. On my PC (which may become out-of-date slowly, but sure isn't a weak machine) it took SNpro about 3 minutes to start up, reading 24 Megs of asteroid data. Each time-step caused several seconds of calculation. But it IS an impressive sight from outer solar system showing up all 17000 objects.

Now I consider it a mere wonder of conincidence, that the Voyager probes as well as all others passing the asteroid belt didn't collide with any object there!

Now this is a real good point the Dr. brings up. That would certainly add to the accuracy of SN. And complete with shadows as seen on Sat. As well we might want to remember for some future version to add in the asteroid belt. Or with a mass several hundred times greater than the asteroid belt we can add the Kuiper belt. And with possibly billions of objects we can get the Oort cloud. All in our solar system. Did I forget anything? Ahh yes. The lonely Centaurs. Hmmmm. If the Oort cloud is up to 100,000 A.U. from the sun is it still in our solar system? Where does our solar system end? This is what happens with SN. Turn it on to look for answers and come away with more questions. Fun stuff even for 50 yr. olds.
