Toxitalk, you can always change one of Oolite's systems into a replica of the Sol system, including all 9 (ok, ok:8) planets & asteroid belt... It's just that nobody has felt compelled to do so.
Maybe one of the many OXP makers on the board will give you a few pointers on how to build a copy of our solar system inside Oolite.
The second and third Elite games both have Earth and the Sol system, but most of Galcop territory can't be visited, just the Old Worlds around Lave (my guess as to why is that Galcop didn't collapse, per se, they just retreated)
