The 55 Cancri system technically has two stars, but most astros have neglected B. B is a M4.5V red dwarf at 1065 AU from the barycentre. If you consider how dim our own Sun shines at that beyond-Kuiper distance, you'll get a picture of how Cancrian colonists might even forget their companion exists.
This might be changing. B has planets. One of them is in its habitable-zone.
I'm pondering how stable this cluttered menagerie. It may be we need to keep watching this system to add, or rule out, more planets.
