Re: [nbos] [AS] Suggestions for AS 2.1
Thu Oct 4th, 2007

I have sort of come into this in the middle of your discussion, but hope
that perhaps this site would be useful.

This particular page allows the user to build a solar system with up to
four planets: you can select the star type, the distance, size, and orbital
excentricity of each planet. The program runs the information as a diagram
with the planets moving. It also gives the probable (Possible?) conditions
on the planet's surface and the expected long term stability of the system.

This site is really fantastic. On other pages it shows the planets and
moons in our solar system, with the moons circling around their planets.

main purpose is to provide users with a means of generating a galactic
sector and its entire contents. I believe the graphic displays are intended
as a means of showing players the general layout of a star system and the
planetary systems within it. I view of the distances involved, I think
trying to show the star
system together with all the planetary and satellite bodies within it
would prodice such a visual muddle that it would defeat the object.

Oh no, I wasn't trying for all levels at once. Even if you could show it in
a fashion that would be useful, I know for a fact the computer *I'm* using
couldn't run it. No, I was suggesting single level displays, just like you
have now. Only instead of being just parent planet/child satellites or
parent star/child planets, I was hoping to include multiples and close
multiples in that. Sounds comparatively simple, until you start realizing
that the fact there's an empty spot in the center of the system changes
*everything* in the calculations.

What I was actually *hoping* for was to be able to give the program the
basic orbital elements and have it display something fairly near the level
of the Java applet shown on this link:

That applet is ChView2, btw. I'm trying to figure out how to define
barycenters in that, but having little luck so far. Then again, I don't
claim to be a programmer either. I was close enough to be able to come up
with a quick and dirty test of a Navy mainframe, but I've never been able
to make a computer sit up and beg like the guys who write this stuff for a
