I'm right now looking into accrete
From the accrete webpage:
Accrete is from the 70's and I've only found one later program, stargen:Accrete is a physical simulation of solar system planet formation. This simulation works by modelling a dust cloud around a Sun-like star, injecting a series of masses which collect dust, and form planets by accretion.
While accrete gives you a text output of formed planets/planetoids and star, Stargen gives you a grafic printout where
planets from our solar system is borrowed to represent the simulated system.
Basically I'm looking for more modern versions for simulating planet/solar system formation.
Anyway,
this is what an accrete session will look like:

And, er... No, I couldn't possibly tell, straight out, what use this could be for the Vega Strike project but I just had me a little detour from my original
task to render me some planets.
