Way back in 1996, George Gatewood found that the nearby (only 8.3LY away) red dwarf star Lalande 21185 seemed to have a planetary system. For some reason it isn't listed in the major catalogs of extrasolar planetary systems, so it's not included in Celestia's extrasolar.ssc file.
http://www.lns.cornell.edu/~seb/celestia/lalande.ssc defines orbits for two of its planets. It includes InfoURLs for two of the abstracts describing the system.
