A multiplanet system of super-Earths orbiting the brightest red dwarf star GJ 887
(aka Lacaille 9352, location of Fand in the Revelation Space books).
For the last decade or so it's been obvious that there'll come a point (if it hasn't already happened) where our knowledge of exoplanets conflicts with the alien solar system worldbuilding in the RS series, which has its origins in stories written more than thirty years ago.
Given how little we ever expected to know about exoplanets when I started studying astronomy. I couldn't be happier about that.
