Twelve astronomical units out from the massive star orbits a Class III Gas Giant, Achenar 4. This relatively small and blue gas giant has caught in its orbit the moon - Achenar 4 A. This small rocky world 0.009 times the earth's mass is tidally locked with the gas giant which it orbits in 9 days. Temperatures on this planet are still above boiling, but ground facilities exist at Greenstein Silo. The military base exports non-lethal weapons, hydrogen fuel and assorted scrap.
