The fainter star to the northwest of Iota2 Cygni is Iota1 Cygni. The two stars are unrelated, and Iota1 lies more than two hundred light years farther from the Sun than Iota2. (The star of similar brightness to the southeast is the dwarf HR 7451, which is actually considerably closer to Earth than either of the two Iota stars.) Imagery provided by Aladin sky atlas
