NotesA system of red dwarf stars notable for their proximity to the Solar System, the Gliese 1245 system lies just fifteen light years from the Sun. The system contains three red dwarfs; as well as the pair Gliese 1245 A and B, Gliese 1245 A has a third low-mass red star, designated Gliese 1245 C, in a close orbit.

* Different sources apply the variable designation 'V1581 Cygni' in different ways. Some assign it to the individual component star Gliese 1245 A, while others prefer to use it to refer to Gliese 1245 A and B (both of which are flare stars) as a pair.
