[1] Philippe Delorme, of the Institute of Planetology and Astrophysics of Grenoble in France and his team, including researchers at Université de Montréal in Canada, detected CFBDSIR2149's infrared signature using the Canada-France-Hawaii Telescope.

[4] An estimate assuming it to be part of the AB Doradus moving group would result in a distance of 40±4 parsecs (130±13 light-years) from Earth.

[2] In the discovery paper, CFBDSIR 2149-0403 was claimed to possibly be a kinematic member of the AB Doradus moving group (ABDMG).

[6] If so, this object would be likely a free-floating planet with a mass lower than the limit for deuterium burning (roughly 13 MJ).

[1] Spectroscopy observations have found light absorption by gaseous methane and water in the object's atmosphere.
