It has a very complex orbit.

“I recently learned that more star systems than not are actually double stars. Completely floored me”
Some decades ago it was estimated only about one in four solar systems had only one star, while three out of four solar systems were binary or multiple star systems. Our closest neighboring solar system, Centauri, includes Alpha Centauri and Beta Centauri orbiting each other as a binary star system with a third star, Proxima Centauri, orbiting the binary pair.
I'll try to run up a video simulation of that later today.
But, if you don't hear from me ...
His original short story was written in 1941.
It was later made into a movie.
In 1988, Nightfall, a low-budget movie was produced based upon the story. The movie was shot on location at the Arcosanti Project, using the resident community members as background actors. Another film version, Nightfall, was made in 2000.
Then in 1990, Asimov and Robert Silverberg collaborated on a complete novel based upon the short story, filling in background about the events leading up to the destruction of civilization. There was a semi-religious group that sought to preserve their civilization through various means because their ancestors had left instructions on what was going to happen, but they were never completely successful, and the people were basically thrown into the equivalent of the stone age...............
At some point the six suns must all align into one unit, as visible from the planet, so that as the planet rotates there is a ‘sunset’ and STARS and the rest of the UNIVERSE comes into view for half a rotation. ......
Your computer sim should start at the point where they all align, then calculate their various orbits so that they will not align again for roughly 2000 years or so.
I’d assume that the planet was orbiting at least one of the stars in the middle or two if it was a binary star with 4 others at various distances outside the gravity well of the first one or two...............
It has a very complex orbit.
I wonder if their stars think they know it all like our stars do.....
Oh yes.
Remember Mel Allen?
I once flew in a Lockheed TriStar.
You'll probably like these two old clips I found on youtube when looking for those other commercials.
Thanks for the links.
