    I wrote the authors of that story asking them how "rogue planets" can be called "planets" since they don't clear the orbital path around a star. Isn't this why Pluto go demoted? I don't care its 6 times Jupiter's mass it's still a planetoid according to the new official definition!

      a weird deal. We sorta feel we know what a planet is, especially when orbiting a star. But there's going to a lot of stuff out that, some stuff that got ejected from solar nebula/disks and stuff that just accreted. From little comets and metal ingots by the trillions to brown dwarfs on the verge of starhood. Imagine a largish earth-like world, with lots of latent internal heat, and a watery surface something like ours.

      Except it's frozen rock solid at about 3 deg K. A thick cap of ice over a deep, warm internal ocean, maybe pools of neon or nitrogen stirring gently on the ice. Imagine life arose to intelligence there, under the ice, cracked out off that surface with instruments and discovered they were utterly alone drifting in interstellar space with the nearest solid body light-years away.
