While most planets that we are familiar with stick relatively close to their host star in a predictable orbit, some planets seem to have been knocked out of their orbits, floating through space free ...

what if a planet did not need a star at all? This is the provocative question at the heart of an emerging astronomical debate, wherein the discovery of rogue planets-worlds free-floating in the galaxy ...
