Its believed that 80% of the stars in the universe are red dwarfs and are only visible to us in infrared light. Seems like I read that we discovered one only about 6 light years away a few years back.
Considering the possibility that red dwarfs may last for as much as a trillion years (yes with a T) planets around them would be good places for life to exist. However the planet needs to be so close as to be tidally locked which presents problems for life. Still, the variables are nearly infinite so who knows.
Glad you're planning ahead!
DNA would have come up with some solution to the sleep problem ~ and being a planet quite a bit larger than Earth, the twilight zone is going to be quite a bit of territory for life to DO STUFF.
Only big problem I see in this is the highwinds flowing from cold to hot, or hot to cold, at various altitudes. They could very well drive ocean currents that would create some high stress regions ~
So, what to do with these planets ~ if there really are as many of them out there as we think?
We probably want to stay away from them since they may already be spoken for by more advanced civilizations ~ this stuff, after all, would constitute most of the best real estate in the cosmos. Second best are the various Dyson Spheres we may have already discovered (large black circular areas emitting infrared and nothing else ~ that's a Dyson Sphere with an internal central star Fur Shur). We are not likely to find those places hospitable either.
Could be as johnny come latelys we may need to focus instead on "Dark matter worlds" ~ out of sight, otherwise desolate, but amenable to human use if we can get some new, cheap, LENR on line).
