[QUOTE="Xeviat, post: 5357500, member: 57494"] I'm not so much concerned with specifically modeling 581g anymore, especially considering it is in the "unconfirmed" pile of planets again. I'm looking at a planet in a similar situation, more like Aurilia (though I don't want the night-side glacier to be so encompasing; I figure more ocean on the planet would lead to better heat transfer). To get a moon that nearly eclipses a red dwarf in the sky of a tidally locked planet, the moon is going to need to appear larger than ours. This means it needs to be considerably closer, or considerably bigger. It could be bigger, as the planet can be bigger, but some have pointed out that large satelites appear to be rare from our own solar system's guidelines (our own moon is throught to have come from a massive colision). A similar situation could have occured. Now, what I'm thinking could be interesting, but still simultaneously useful for time keeping and suitably different from Earth, would be if such a planet had a few moons. They would create more frequent eclipses of the sun, which would aid in the tracking of time. Additionally, at least closer ot the twilight, if the star has more planets further interior, these could be seen as stars moving in and out of the star, and they'd prove useful (but the twilight side will be able to see the actual stars, which will drift in the sky rather quickly). I also think I will be using chemosynthesis as the primary source of food on the night side. Vast gyser fields and hot springs will support chemosynthetic bacteria and fungi that animals feed off of. Other life will be supported by organics brought in from the day side (the ocean should still get a good supply of plankton and such on the ever circulating ocean currents). I'd prefer to keep the magical ecosystems to a minimum, but this is because of my preference towards worldbuilding with an eye to Sci Fi. Thanks for everyone's help. This is a fun discussion.
