I'm looking for some ideas. I have been working on my generated sectors, and have begun to look at some of the details. One system is a binary K0 V, with a M dwarf orbiting it in the habitable zone. There is a very decent satellite around a SGG in orbit 0 of the dwarf - so, within the habitable zone of the primary! I found a calculator online to give me the orbital periods (using the numbers for mass and distances in LBB6).
- The M dwarf has an orbital period of a touch over 37 weeks (call it 9 months).
- The SGG has an orbital period around the dwarf of almost 4 1/2 weeks.
- The moon [C660545-6] has a period around the SGG (at 510,000km) of about a week and a half.
So, the moon goes 'round the SGG, which goes 'round the dwarf, which goes 'round the Orange sub-giant. I assume the SGG will not block the dwarf from visibility when the moon is on the far side of it. I also assume the SGG will transit from the far edge of the habitable zone to the near edge as it dances about the dwarf.
What sort of funky day/night cycle will this moon have?
Will it be tidally locked to the SGG? I hope not.
I'm thinking the seasons would be pretty wild, assuming a slightly eccentric orbit (a normal one, iow) - week of winter, week of spring, week of summer, week of fall, but with weekly transitions, too, as it goes around the SGG.
How messed up will these people's calendars be?
There are two other inhabited worlds. One is in a closer orbit to the main, so I assume that's a mining concern or research lab or some such. The other is on a smaller moon closer to the SGG (175,000km). It's not quite as nice as the atmosphere is thinner, but it has water [Y445465-5]. (It flies about the SGG every 31+ hours - I think that one could be tidally locked and still have a day/night cycle.)
Is there anywhere I could model this? Put in the parameters and then watch it play out? Or, that someone else could, and maybe record it for me?
Here's the entire system:
(Note: I did fudge the mass numbers for the moons a little, and gave an arbitrary size to the SGG, based on Neptune. So, if you run the numbers and they're a little different, that may be why, besides rounding errors.)
