In the Strategic Decisions for Campaign Play thread we've been talking about plotting star systems as a level of war above the tactical level that we simulate in Armada (and X-Wing and Imperial Assault), but not quite the strategic (SW: Rebellion) or operational level either.
Stefan posted an interesting idea with just a simple map, and Vogons has been thinking about how to expand on that. Tirion is suggesting just using Twilight Imperium maps.
I think an online system generator would be awesome - one that plots out a system: what stars, planets, stations, asteroids, comets, etc. are in the system; where they are, based on respective orbits; and then what the distances between them are.
Some system names are known (from Wookieepedia), including rudimentary data in terms of what the planets and moons are, though this is obviously very incomplete data. However, that's all stuff that could be put in a database, and then have a random engine fill in the missing details.
Such a random engine should operate off of some astrophysical baseline rules: at what distance from the star are you more/less likely to have planets of different types? The pattern in our solar system is that the gas giants are at a certain distance from the sun (~780 million km - 4.5 billion km), with the smaller planets (Pluto notwithstanding) much closer. I'm sure there's reasons for this based in astrophysics, but I don't know what those reasons are.
So, I'm polling the hive mind of nerddom - do you know what some of those baseline rules would be, and what sorts of variables should be kept in mind? I don't think it has to be astrophysically perfect (this is a space fantasy setting, afterall), but just enough to suspend our disbelief.
