L1014 is a dark nebula in the Cygnus constellation. It may be among the most centrally condensed small dark clouds known, perhaps indicative of the earliest stages of star formation processes. This cloud harbors at its core a very young low-mass star named L1014 IRS; some astronomers have suggested that this object may be a brown dwarf or even a rogue planet at the earliest stage of its lifetime.[3]
