too true Pat
A possible free-floating exoplanet, drifting through interstellar space without a star of its own to orbit, has been discovered a hundred light years from Earth. If confirmed, it will be the first of its kind to be proven to exist - and there may be billions more like it out there.
without a star it's just an asteroid surely?
why is it a rogue planet and not a rogue asteroid? planet to me suggests habitable or possibly habitable, like mj12cz alludes, it would be horrendously cold
