Rogue planet or brown dwarf?
An international team of astronomers led by Philippe Delorme of the Grenoble Alpes University in France has recently investigated a mysterious object designated CFBDSIR J214947.2-040308.9 (CFBDSIR 2149-0403 for short) in order to reveal its true nature. The object is assumed to be a young isolated planetary-mass object or a high-metallicity low-mass brown dwarf.
