It's also my understanding that it takes about 2050 years for the Alpha sun and the two distant companion pairs to simultaneously set. At that point the Beta sun is left alone in the sky so darkness ensues when a non-luminous planetary body eclipses Beta. The non-luminous planet may very well eclipse Beta every day but it only causes a black out on the planet Lagash when the other five suns are antipodal to Saro City. An antipodal event that occurs approximately every 2050 years. What if Lagash and another planet of equal size rotate about each other? Do the celestial mechanics work any better? Thank you, -- Don Kuenz KB7RPU Oh dark, dark, dark, amid the blaze of noon, Irrecoverably dark, total eclipse Without all hope of day! -Milton
