NotesAt the heart of the Theta Cygni system is a bright yellow dwarf star somewhat larger and more luminous than the Sun. It has a number of dwarf companion stars (not all of which are categorically identified, but Theta Cygni possibly has three companions, and perhaps as many as five). There are indications that the system may also contain a massive planetary body.
