There are ten planets and one asteroid belt [See 1)] in the system. One of the planets Yeltsin V – Grayson in settled. Due to the Grayson's hostile environment there is extensive space industrial activity in the system. Yeltsin is 31 LY to galactic northeast from Manticore, 22 LY from Casca, and “over” 150 LY from Trevor’s Star. Together with its closest neighbor Endicott, these two systems are the only ones colonized in a sphere of 40 LY placed directly between Manticore and Haven.
Yildun – <CoS, SoSag, HoS> A star system in SL, StC – A1; HL - “around” 28,31. Yildun is "rougly" 183 LY from Earth. The system has no habitable planets but is rich in asteroids and contains the second oldest known wormhole junction, which has three termini. Home of the Technodyne Industries of Yildun, one of SLN's primary builders, with an in-house R&D division which enjoys an enviable prestige. Unfortunaetly the close ties TIY enjoyed with MU and other Mesan corporatoions lead to its involvement in the attempt to undermine SKM's position in the TC prior to its full annexation into SEM.
