I have recieved a request for the original layout of the solar system for our Nemesis Campaign.
I had originally intended to just send it back to the person requesting this, but decided that it may be of interest to anyone reading the story.
I have tried to keep it so that if follows the normal Starfire mechanics as much as possible. There were a fair number of deviations from both rules and real values to try and simplify things, and they will be listed with the body affected or following the list (to the best of my abilities). The radian designation is not exactly acurrate for the planets beyond Jupiter as we placed them in the system hex dictated by their actual plotted position for January 1st 2204. The radian should be close enough from most needs though. In the case of the dwarf planets beyond Neptune, the actual plotted locations are my best estimate as data on some is very limited. In respect to the AB colonies, graviational perturbations made acurrate plotting somewhat difficult over the course of centuries. I had positions plotted, but you will forgive me if I don't type out all of them. If you just scattered them about randomly, you probably have as good a chance to get them close to where they will actually be in 2204 as I do spending hours plotting them.
If you have questions, feel free to ask.

(you could easily use the list of largest asteroids in Wiki, these are just the ones I chose)
Pallas / PE
Juno / US
Vestia / PE

Ownership of all objects within 4AU were proscribed by the Treaty of L2 and reinstated by the Treaty of Mare Serenetatis of 2204. FSC holdings in the AB were created by amendment to Treaty of Mare Serenetatis by the US and PE. China refused to recognize the amendment.
Ownership of all objects beyond 4AU were proscribed by the Treaty of Mare Serenetatis of 2204. Trans Neptune objects were declared to be owned by the first government that could emplace a population of 50,000 colonist for 30 days. This was later applied to all objects beyond the solar system.
For the players (and my) convenience, the outer planets and moons were considered to move by normal Starfire orbital mechanics, with exceptions as noted.

*Ok, the cycle for Luna is to try and keep it close to the actual lunar cycle.
Move it along the 5 tH orbit at one hex per day. This makes it 30 days rather than 28, but is close enough for the kids. When placing it for combat, determine its location for the month by the 5tH orbit, and then move it one hex more distant.
** These pups have very unusual orbital characteristics. I have fairly involved tables laid out for their positions over the course of decades. Each has one page, front and back, of note paper outlining positions by the month. I am not copying that mess over. Sorry. You can have them follow normal orbits (none really come close to that), or sit down and figure it out if you wish. Pluto is pretty easy. Sedna and Orcus I considered close. Eris was my best guess - it might be on the other side of the sun for what little data I had to work with I also had data for Haumea, Makemake, and six other scattered disc objects as O1m or AB colony equivalents, but these listed were the major sites for the game. I was willing to add more scattered disc objects if the game ever got that far, but by then they were jumping to other systems and not interested.
I may have omitted some standard information. Typos are also quite possible. My wife proofreads the story, but not this stuff. If you find errors, I apologise.
You can easily quibble over what body qualifies for what designation, orbital characteristics, etc. O1m vs AB, Extreme vs Desolate vs Hostile, etc, etc, ad nauseum....
If you disagree, you are allowed. If you want to use this as a basis for your own games, feel free with my blessings. Change whatever you disagree with to make yourself and your group happy. Our game has been going for years and 100 turns. Don't plan on me changing it.
I could have made it much more complicated. Feel free to do this if you wish. Some of the work has been started for you. I needed to keep it so that a 12y/o boy could take a fair shot at knowing where the planets, moons, ABs, etc were going to be when figuring out ship movement orders and travel times. I kept the outer body movement patterns unknown until they surveyed them - then I photocopied the sheet and gave them one. And no, I don't have access to a scanner at home or at work so don't ask. Some of the moons as AB equivalents were just as suprises for the players. Until the players surveyed, they had no idea how many I had designated as in orbit of each planet and what they were. They knew about the 02m and 01m around the planets, the rest was a mystery.
Hope this satisfies the curious. Thanks again for reading.
