this would a strange place to live:

Gliese 581g, dubbed a "Goldilocks planet" by co-discoverer R. Paul Butler of the Carnegie Institution of Washington, is tidally locked, meaning that the same face of the planet always is oriented toward the sun, with another residing in perpetual darkness. Life could be found near the terminator, or the intersection of the two regions.
that means no night and day cycle, just choose either (day side = probably too hot, night side = probably too cold, you'd have to live near the intersection)
interesting, but probably way too far to envision colonization?
